1 INTRODUCTION
This Field Investigation Report presents the results of the West Waterway (WW) Sediment Characterization Study conducted in Seattle Washington (Figure 1) Sediment samples were collected and analyzed in accordance with the Dredged Material Management Program (DMMP)-approved Quality Assurance Project Plan (QAPP Anchor QEA 2015) Bioassay samples were analyzed in accordance with the Port of Seattlersquos (Portrsquos) DMMP-approved Terminal 5 Sampling and Analysis Plan (SAP Hart Crowser 2014) and the latest DMMP guidance (DMMO 2014)
The QAPP was written to ensure that collection sampling and analysis of sediment followed DMMP guidance to estimate potential suitability of dredged sediment for open-water disposal but was not intended to provide a full characterization to support a suitability determination
Specific information provided in this Field Investigation Report includes the following

11 Project Description
The study was conducted by the Port for the US Army Corps of Engineers (USACE) in support of the Seattle Harbor Navigation Improvement Feasibility Study to analyze and evaluate navigation improvements to the WW The objective of the study was to estimate the potential suitability of subtidal dredged materials for open-water disposal andor beneficial reuse
The current authorized navigation channel elevation is -34 feet mean lower low water (MLLW) Multiple deepening scenarios are being assessed (-51 -53 -55 feet andor -57 feet MLLW) The estimated volumes of sediment that may be suitable for open-water disposal andor beneficial reuse for each deepening scenario will ultimately be incorporated into the Feasibility Study

Field Investigation Report August 2015 West Waterway Sediment Characterization 2 110003-0102
2 SAMPLING METHODS
Sampling was conducted in accordance with the DMMP-approved QAPP (Anchor QEA 2015) The QAPP provides the sample design target sampling locations procedures for sample collection and processing data QC and data reporting requirements Any sampling method deviations from the QAPP are discussed in this section
The QAPP sampling plan included 23 sediment core stations within the boundary of the WW Sediment Operable Unit (OU) and the WW navigation channel (Figure 2) A total of 27 cores were collected from these locations by vibracore collection method Cores were transported to Analytical Resources Inc (ARI) for processing and physical characterization and then submitted for analysis Daily field activity is documented in Appendix A
21 Sampling Vessel Navigation and Positioning
Sampling was conducted aboard the research vessel (RV) Nancy Ann operated by subcontractor Marine Sampling Services using a vibracorer A differential global positioning system (DGPS) unit located on the top of the vibracore A-frame was used for positioning The DGPS was connected to a computer with software allowing the vessel operator to access the US Coast Guard differential signal from Seattle Washington for positioning The software was used to navigate to the proposed sampling stations and record the actual sampling position at the time of sampling Coordinates were recorded digitally and on core collection field logs in latitude and longitude as decimal minutes to the fourth decimal place using the North American Datum of 1983 (NAD83)
A fathometer mounted on the bow of RV Nancy Ann was used to measure depth Water depth was taken prior to lowering the vibracore to match station depth with the anticipated mudline to capture sediment from each theoretical dredge scenario described in the QAPP At each sampling station water depth (to the nearest tenth of a foot) was recorded on core collection logs (Appendix A) Predicted tide height based on National Oceanic and Atmospheric Administration (NOAA) predictions for Lockheed Shipyard were used to calculate mudline elevation in MLLW by multiplying the water depth by -1 then adding the predicted tidal elevation at the time of collection Prior to core processing preliminary tide measurements from NOAA were used to recalculate the actual mudline elevations used to

Sampling Methods
determine sample intervals in core processing These calculations can be found on the core collection logs
Twice-daily DGPS horizontal positioning and fathometer accuracy checks were performed at a piling at the southwestern corner of the Harbor Island Marina pier DGPS latitude and longitude readings were taken at a stationary piling at the marina before and after sampling each day Coordinates were recorded and compared to one another to assess DGPS precision throughout the sampling day and during the sampling effort All DGPS measurements were within plusmn179 feet of each other A lead line was used to measure depth and compared with the fathometer reading All lead line and fathometer mudline elevation measurements were within plusmn04 foot of each other
22 Core Collection
Sample cores from 23 discrete sampling stations were collected by vibracore on February 2 through 5 2015 Target and actual core locations are displayed in Figure 2 To obtain sufficient material for potential bioassay testing two cores were collected at each of four predetermined sample stations Actual core locations date collection time and mudline elevation are provided in Table 1
Table 1 also shows core drive penetration recovery measurement and percent recovery All accepted cores achieved the required penetration of 75 However not all cores were accepted on the first attempt One or more attempts were made at three locations (WWD01 WWD04 and WWD05) before acceptable cores were collected A brief description of coring attempts at these three locations is provided below
bull Station WWD01 required eight attempts to get an acceptable core Three attempts on February 2 2015 failed due to poor or no recovery when hard material at approximately 8 to 10 feet below mudline separated the nose of the aluminum core from the sample tube and resulted in loss of material from the core during pull-out The station was attempted again on February 5 2015 Poor or no recovery was encountered twice more due to loss of the nose Two more attempts encountered a steep grade on the bottom which caused the vibracore apparatus to tip with no sediment collected The target drive penetration was then decreased from 15 feet to

Sampling Methods
10 feet to avoid driving through the obstruction and the final eighth core attempt was acceptable
bull Station WWD04 required two attempts The first attempt had zero recovery after losing the nose on a solid surface during pull-out The sample station was moved 108 feet southwest from the target location and the second attempt was acceptable
bull Station WWD05 required two attempts In the first attempt the vibracore unit tipped over after freefall was initiated This core attempt was rejected but a second attempt was acceptable
Most samples were within 10 feet of the proposed location with some exceptions Circumstances related to the movement of samples WWD01 and WWD04 are explained above Other modifications are described below
bull WWD19 was moved 287 feet north to obtain the proposed sample mudline elevation bull WWD21 was relocated 211 feet northeast to obtain the proposed sample mudline
elevation bull WWD22 was relocated 506 feet southwest in order to maintain spatial variation in
sampling The Port and USACE recommended moving this sample bull WWD23 was relocated because it was obstructed by a dry dock After consultation
with the Port and USACE the sample station was moved 1126 feet southwest
The mudline elevation at sample stations was within plusmn15 feet of the target mudline elevation with the exception of WWD23 which was 56 feet deeper than the target mudline of -45 feet MLLW As explained above this sample location was obstructed by the dry dock and USACE approved moving the station and the change in mudline elevation
23 Sample Processing
Sample processing was conducted in accordance with the QAPP in order to classify distinct layers of sediment for analysis and judgment of potential disposal suitability At the end of each sampling day the cores were transferred to ARI and held upright at 4degC until processing Processing began on February 3 2015 and concluded on February 9 2015
Field Investigation Report August 2015 West Waterway Sediment Characterization 5 110003-0102
Sampling Methods
When processed the core caps were removed and the core was cut longitudinally using a circular saw Core segments were placed end-to-end from top to bottom to show the entire core length for photographing and sample-splitting The core was split with decontaminated stainless steel knives or spatulas into two halves for sampling The sulfides samples were collected from one-half of the core immediately after splitting placed in jars with 5 milliliters of 2-Normal zinc acetate per 30 grams and shaken vigorously to preserve the samples
Prior to further sampling field staff re-measured cores and delineated sampling intervals based on preliminary tide data from NOAA All cores were logged for major lithological features classified according to the Unified Soil Classification System and photographed (Appendix A) Sample intervals were based on recovered depth not corrected for length based on core recovery Elevations of core intervals (MLLW) and sample depths relative to mudline are shown in Table 2 Samples were placed in decontaminated stainless steel bowls and mixed until homogenous in color and texture using a decontaminated stainless steel mixing spoon The sediment was then spooned into laboratory-supplied jars for analyses A chain-of-custody form was logged by the processing staff and relinquished to the laboratory staff (Appendix A) Fifty-seven samples were collected and submitted for analysis or sample archive A complete sample inventory including represented intervals and requested chemistry is shown in Table 3
Four stations required two co-located cores to achieve sufficient volume for bioassay archives Co-located cores differed by less than plusmn02 foot in mudline elevation with the exception of WWD02 which differed by 22 feet To adjust for the 22-foot difference in this sample the core closest to the target mudline elevation was deemed the primary core and intervals in the second core were adjusted to match the elevations of sampled strata from the primary core This decision was supported by lithography and physical sediment characteristics and was approved by USACE
24 Sediment Grab Collection
To collect a reference sample for comparison to samples submitted for biological testing a sediment grab sample was collected from a DMMP-approved reference area in Carr Inlet
Field Investigation Report August 2015 West Waterway Sediment Characterization 6 110003-0102
Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate

Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

1 INTRODUCTION
This Field Investigation Report presents the results of the West Waterway (WW) Sediment Characterization Study conducted in Seattle Washington (Figure 1) Sediment samples were collected and analyzed in accordance with the Dredged Material Management Program (DMMP)-approved Quality Assurance Project Plan (QAPP Anchor QEA 2015) Bioassay samples were analyzed in accordance with the Port of Seattlersquos (Portrsquos) DMMP-approved Terminal 5 Sampling and Analysis Plan (SAP Hart Crowser 2014) and the latest DMMP guidance (DMMO 2014)
The QAPP was written to ensure that collection sampling and analysis of sediment followed DMMP guidance to estimate potential suitability of dredged sediment for open-water disposal but was not intended to provide a full characterization to support a suitability determination
Specific information provided in this Field Investigation Report includes the following

11 Project Description
The study was conducted by the Port for the US Army Corps of Engineers (USACE) in support of the Seattle Harbor Navigation Improvement Feasibility Study to analyze and evaluate navigation improvements to the WW The objective of the study was to estimate the potential suitability of subtidal dredged materials for open-water disposal andor beneficial reuse
The current authorized navigation channel elevation is -34 feet mean lower low water (MLLW) Multiple deepening scenarios are being assessed (-51 -53 -55 feet andor -57 feet MLLW) The estimated volumes of sediment that may be suitable for open-water disposal andor beneficial reuse for each deepening scenario will ultimately be incorporated into the Feasibility Study

2 SAMPLING METHODS
Sampling was conducted in accordance with the DMMP-approved QAPP (Anchor QEA 2015) The QAPP provides the sample design target sampling locations procedures for sample collection and processing data QC and data reporting requirements Any sampling method deviations from the QAPP are discussed in this section
The QAPP sampling plan included 23 sediment core stations within the boundary of the WW Sediment Operable Unit (OU) and the WW navigation channel (Figure 2) A total of 27 cores were collected from these locations by vibracore collection method Cores were transported to Analytical Resources Inc (ARI) for processing and physical characterization and then submitted for analysis Daily field activity is documented in Appendix A
21 Sampling Vessel Navigation and Positioning
Sampling was conducted aboard the research vessel (RV) Nancy Ann operated by subcontractor Marine Sampling Services using a vibracorer A differential global positioning system (DGPS) unit located on the top of the vibracore A-frame was used for positioning The DGPS was connected to a computer with software allowing the vessel operator to access the US Coast Guard differential signal from Seattle Washington for positioning The software was used to navigate to the proposed sampling stations and record the actual sampling position at the time of sampling Coordinates were recorded digitally and on core collection field logs in latitude and longitude as decimal minutes to the fourth decimal place using the North American Datum of 1983 (NAD83)
A fathometer mounted on the bow of RV Nancy Ann was used to measure depth Water depth was taken prior to lowering the vibracore to match station depth with the anticipated mudline to capture sediment from each theoretical dredge scenario described in the QAPP At each sampling station water depth (to the nearest tenth of a foot) was recorded on core collection logs (Appendix A) Predicted tide height based on National Oceanic and Atmospheric Administration (NOAA) predictions for Lockheed Shipyard were used to calculate mudline elevation in MLLW by multiplying the water depth by -1 then adding the predicted tidal elevation at the time of collection Prior to core processing preliminary tide measurements from NOAA were used to recalculate the actual mudline elevations used to

Sampling Methods
determine sample intervals in core processing These calculations can be found on the core collection logs
Twice-daily DGPS horizontal positioning and fathometer accuracy checks were performed at a piling at the southwestern corner of the Harbor Island Marina pier DGPS latitude and longitude readings were taken at a stationary piling at the marina before and after sampling each day Coordinates were recorded and compared to one another to assess DGPS precision throughout the sampling day and during the sampling effort All DGPS measurements were within plusmn179 feet of each other A lead line was used to measure depth and compared with the fathometer reading All lead line and fathometer mudline elevation measurements were within plusmn04 foot of each other
22 Core Collection
Sample cores from 23 discrete sampling stations were collected by vibracore on February 2 through 5 2015 Target and actual core locations are displayed in Figure 2 To obtain sufficient material for potential bioassay testing two cores were collected at each of four predetermined sample stations Actual core locations date collection time and mudline elevation are provided in Table 1
Table 1 also shows core drive penetration recovery measurement and percent recovery All accepted cores achieved the required penetration of 75 However not all cores were accepted on the first attempt One or more attempts were made at three locations (WWD01 WWD04 and WWD05) before acceptable cores were collected A brief description of coring attempts at these three locations is provided below
bull Station WWD01 required eight attempts to get an acceptable core Three attempts on February 2 2015 failed due to poor or no recovery when hard material at approximately 8 to 10 feet below mudline separated the nose of the aluminum core from the sample tube and resulted in loss of material from the core during pull-out The station was attempted again on February 5 2015 Poor or no recovery was encountered twice more due to loss of the nose Two more attempts encountered a steep grade on the bottom which caused the vibracore apparatus to tip with no sediment collected The target drive penetration was then decreased from 15 feet to
Field Investigation Report August 2015 West Waterway Sediment Characterization 4 110003-0102
Sampling Methods
10 feet to avoid driving through the obstruction and the final eighth core attempt was acceptable
bull Station WWD04 required two attempts The first attempt had zero recovery after losing the nose on a solid surface during pull-out The sample station was moved 108 feet southwest from the target location and the second attempt was acceptable
bull Station WWD05 required two attempts In the first attempt the vibracore unit tipped over after freefall was initiated This core attempt was rejected but a second attempt was acceptable
Most samples were within 10 feet of the proposed location with some exceptions Circumstances related to the movement of samples WWD01 and WWD04 are explained above Other modifications are described below
bull WWD19 was moved 287 feet north to obtain the proposed sample mudline elevation bull WWD21 was relocated 211 feet northeast to obtain the proposed sample mudline
elevation bull WWD22 was relocated 506 feet southwest in order to maintain spatial variation in
sampling The Port and USACE recommended moving this sample bull WWD23 was relocated because it was obstructed by a dry dock After consultation
with the Port and USACE the sample station was moved 1126 feet southwest
The mudline elevation at sample stations was within plusmn15 feet of the target mudline elevation with the exception of WWD23 which was 56 feet deeper than the target mudline of -45 feet MLLW As explained above this sample location was obstructed by the dry dock and USACE approved moving the station and the change in mudline elevation
23 Sample Processing
Sample processing was conducted in accordance with the QAPP in order to classify distinct layers of sediment for analysis and judgment of potential disposal suitability At the end of each sampling day the cores were transferred to ARI and held upright at 4degC until processing Processing began on February 3 2015 and concluded on February 9 2015
Field Investigation Report August 2015 West Waterway Sediment Characterization 5 110003-0102
Sampling Methods
When processed the core caps were removed and the core was cut longitudinally using a circular saw Core segments were placed end-to-end from top to bottom to show the entire core length for photographing and sample-splitting The core was split with decontaminated stainless steel knives or spatulas into two halves for sampling The sulfides samples were collected from one-half of the core immediately after splitting placed in jars with 5 milliliters of 2-Normal zinc acetate per 30 grams and shaken vigorously to preserve the samples
Prior to further sampling field staff re-measured cores and delineated sampling intervals based on preliminary tide data from NOAA All cores were logged for major lithological features classified according to the Unified Soil Classification System and photographed (Appendix A) Sample intervals were based on recovered depth not corrected for length based on core recovery Elevations of core intervals (MLLW) and sample depths relative to mudline are shown in Table 2 Samples were placed in decontaminated stainless steel bowls and mixed until homogenous in color and texture using a decontaminated stainless steel mixing spoon The sediment was then spooned into laboratory-supplied jars for analyses A chain-of-custody form was logged by the processing staff and relinquished to the laboratory staff (Appendix A) Fifty-seven samples were collected and submitted for analysis or sample archive A complete sample inventory including represented intervals and requested chemistry is shown in Table 3
Four stations required two co-located cores to achieve sufficient volume for bioassay archives Co-located cores differed by less than plusmn02 foot in mudline elevation with the exception of WWD02 which differed by 22 feet To adjust for the 22-foot difference in this sample the core closest to the target mudline elevation was deemed the primary core and intervals in the second core were adjusted to match the elevations of sampled strata from the primary core This decision was supported by lithography and physical sediment characteristics and was approved by USACE
24 Sediment Grab Collection
To collect a reference sample for comparison to samples submitted for biological testing a sediment grab sample was collected from a DMMP-approved reference area in Carr Inlet
Field Investigation Report August 2015 West Waterway Sediment Characterization 6 110003-0102
Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate

Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

1 INTRODUCTION
This Field Investigation Report presents the results of the West Waterway (WW) Sediment Characterization Study conducted in Seattle Washington (Figure 1) Sediment samples were collected and analyzed in accordance with the Dredged Material Management Program (DMMP)-approved Quality Assurance Project Plan (QAPP Anchor QEA 2015) Bioassay samples were analyzed in accordance with the Port of Seattlersquos (Portrsquos) DMMP-approved Terminal 5 Sampling and Analysis Plan (SAP Hart Crowser 2014) and the latest DMMP guidance (DMMO 2014)
The QAPP was written to ensure that collection sampling and analysis of sediment followed DMMP guidance to estimate potential suitability of dredged sediment for open-water disposal but was not intended to provide a full characterization to support a suitability determination
Specific information provided in this Field Investigation Report includes the following

11 Project Description
The study was conducted by the Port for the US Army Corps of Engineers (USACE) in support of the Seattle Harbor Navigation Improvement Feasibility Study to analyze and evaluate navigation improvements to the WW The objective of the study was to estimate the potential suitability of subtidal dredged materials for open-water disposal andor beneficial reuse
The current authorized navigation channel elevation is -34 feet mean lower low water (MLLW) Multiple deepening scenarios are being assessed (-51 -53 -55 feet andor -57 feet MLLW) The estimated volumes of sediment that may be suitable for open-water disposal andor beneficial reuse for each deepening scenario will ultimately be incorporated into the Feasibility Study

2 SAMPLING METHODS
Sampling was conducted in accordance with the DMMP-approved QAPP (Anchor QEA 2015) The QAPP provides the sample design target sampling locations procedures for sample collection and processing data QC and data reporting requirements Any sampling method deviations from the QAPP are discussed in this section
The QAPP sampling plan included 23 sediment core stations within the boundary of the WW Sediment Operable Unit (OU) and the WW navigation channel (Figure 2) A total of 27 cores were collected from these locations by vibracore collection method Cores were transported to Analytical Resources Inc (ARI) for processing and physical characterization and then submitted for analysis Daily field activity is documented in Appendix A
21 Sampling Vessel Navigation and Positioning
Sampling was conducted aboard the research vessel (RV) Nancy Ann operated by subcontractor Marine Sampling Services using a vibracorer A differential global positioning system (DGPS) unit located on the top of the vibracore A-frame was used for positioning The DGPS was connected to a computer with software allowing the vessel operator to access the US Coast Guard differential signal from Seattle Washington for positioning The software was used to navigate to the proposed sampling stations and record the actual sampling position at the time of sampling Coordinates were recorded digitally and on core collection field logs in latitude and longitude as decimal minutes to the fourth decimal place using the North American Datum of 1983 (NAD83)
A fathometer mounted on the bow of RV Nancy Ann was used to measure depth Water depth was taken prior to lowering the vibracore to match station depth with the anticipated mudline to capture sediment from each theoretical dredge scenario described in the QAPP At each sampling station water depth (to the nearest tenth of a foot) was recorded on core collection logs (Appendix A) Predicted tide height based on National Oceanic and Atmospheric Administration (NOAA) predictions for Lockheed Shipyard were used to calculate mudline elevation in MLLW by multiplying the water depth by -1 then adding the predicted tidal elevation at the time of collection Prior to core processing preliminary tide measurements from NOAA were used to recalculate the actual mudline elevations used to

Sampling Methods
determine sample intervals in core processing These calculations can be found on the core collection logs
Twice-daily DGPS horizontal positioning and fathometer accuracy checks were performed at a piling at the southwestern corner of the Harbor Island Marina pier DGPS latitude and longitude readings were taken at a stationary piling at the marina before and after sampling each day Coordinates were recorded and compared to one another to assess DGPS precision throughout the sampling day and during the sampling effort All DGPS measurements were within plusmn179 feet of each other A lead line was used to measure depth and compared with the fathometer reading All lead line and fathometer mudline elevation measurements were within plusmn04 foot of each other
22 Core Collection
Sample cores from 23 discrete sampling stations were collected by vibracore on February 2 through 5 2015 Target and actual core locations are displayed in Figure 2 To obtain sufficient material for potential bioassay testing two cores were collected at each of four predetermined sample stations Actual core locations date collection time and mudline elevation are provided in Table 1
Table 1 also shows core drive penetration recovery measurement and percent recovery All accepted cores achieved the required penetration of 75 However not all cores were accepted on the first attempt One or more attempts were made at three locations (WWD01 WWD04 and WWD05) before acceptable cores were collected A brief description of coring attempts at these three locations is provided below
bull Station WWD01 required eight attempts to get an acceptable core Three attempts on February 2 2015 failed due to poor or no recovery when hard material at approximately 8 to 10 feet below mudline separated the nose of the aluminum core from the sample tube and resulted in loss of material from the core during pull-out The station was attempted again on February 5 2015 Poor or no recovery was encountered twice more due to loss of the nose Two more attempts encountered a steep grade on the bottom which caused the vibracore apparatus to tip with no sediment collected The target drive penetration was then decreased from 15 feet to
Field Investigation Report August 2015 West Waterway Sediment Characterization 4 110003-0102
Sampling Methods
10 feet to avoid driving through the obstruction and the final eighth core attempt was acceptable
bull Station WWD04 required two attempts The first attempt had zero recovery after losing the nose on a solid surface during pull-out The sample station was moved 108 feet southwest from the target location and the second attempt was acceptable
bull Station WWD05 required two attempts In the first attempt the vibracore unit tipped over after freefall was initiated This core attempt was rejected but a second attempt was acceptable
Most samples were within 10 feet of the proposed location with some exceptions Circumstances related to the movement of samples WWD01 and WWD04 are explained above Other modifications are described below
bull WWD19 was moved 287 feet north to obtain the proposed sample mudline elevation bull WWD21 was relocated 211 feet northeast to obtain the proposed sample mudline
elevation bull WWD22 was relocated 506 feet southwest in order to maintain spatial variation in
sampling The Port and USACE recommended moving this sample bull WWD23 was relocated because it was obstructed by a dry dock After consultation
with the Port and USACE the sample station was moved 1126 feet southwest
The mudline elevation at sample stations was within plusmn15 feet of the target mudline elevation with the exception of WWD23 which was 56 feet deeper than the target mudline of -45 feet MLLW As explained above this sample location was obstructed by the dry dock and USACE approved moving the station and the change in mudline elevation
23 Sample Processing
Sample processing was conducted in accordance with the QAPP in order to classify distinct layers of sediment for analysis and judgment of potential disposal suitability At the end of each sampling day the cores were transferred to ARI and held upright at 4degC until processing Processing began on February 3 2015 and concluded on February 9 2015
Field Investigation Report August 2015 West Waterway Sediment Characterization 5 110003-0102
Sampling Methods
When processed the core caps were removed and the core was cut longitudinally using a circular saw Core segments were placed end-to-end from top to bottom to show the entire core length for photographing and sample-splitting The core was split with decontaminated stainless steel knives or spatulas into two halves for sampling The sulfides samples were collected from one-half of the core immediately after splitting placed in jars with 5 milliliters of 2-Normal zinc acetate per 30 grams and shaken vigorously to preserve the samples
Prior to further sampling field staff re-measured cores and delineated sampling intervals based on preliminary tide data from NOAA All cores were logged for major lithological features classified according to the Unified Soil Classification System and photographed (Appendix A) Sample intervals were based on recovered depth not corrected for length based on core recovery Elevations of core intervals (MLLW) and sample depths relative to mudline are shown in Table 2 Samples were placed in decontaminated stainless steel bowls and mixed until homogenous in color and texture using a decontaminated stainless steel mixing spoon The sediment was then spooned into laboratory-supplied jars for analyses A chain-of-custody form was logged by the processing staff and relinquished to the laboratory staff (Appendix A) Fifty-seven samples were collected and submitted for analysis or sample archive A complete sample inventory including represented intervals and requested chemistry is shown in Table 3
Four stations required two co-located cores to achieve sufficient volume for bioassay archives Co-located cores differed by less than plusmn02 foot in mudline elevation with the exception of WWD02 which differed by 22 feet To adjust for the 22-foot difference in this sample the core closest to the target mudline elevation was deemed the primary core and intervals in the second core were adjusted to match the elevations of sampled strata from the primary core This decision was supported by lithography and physical sediment characteristics and was approved by USACE
24 Sediment Grab Collection
To collect a reference sample for comparison to samples submitted for biological testing a sediment grab sample was collected from a DMMP-approved reference area in Carr Inlet
Field Investigation Report August 2015 West Waterway Sediment Characterization 6 110003-0102
Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate

Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

1 INTRODUCTION
This Field Investigation Report presents the results of the West Waterway (WW) Sediment Characterization Study conducted in Seattle Washington (Figure 1) Sediment samples were collected and analyzed in accordance with the Dredged Material Management Program (DMMP)-approved Quality Assurance Project Plan (QAPP Anchor QEA 2015) Bioassay samples were analyzed in accordance with the Port of Seattlersquos (Portrsquos) DMMP-approved Terminal 5 Sampling and Analysis Plan (SAP Hart Crowser 2014) and the latest DMMP guidance (DMMO 2014)
The QAPP was written to ensure that collection sampling and analysis of sediment followed DMMP guidance to estimate potential suitability of dredged sediment for open-water disposal but was not intended to provide a full characterization to support a suitability determination
Specific information provided in this Field Investigation Report includes the following

11 Project Description
The study was conducted by the Port for the US Army Corps of Engineers (USACE) in support of the Seattle Harbor Navigation Improvement Feasibility Study to analyze and evaluate navigation improvements to the WW The objective of the study was to estimate the potential suitability of subtidal dredged materials for open-water disposal andor beneficial reuse
The current authorized navigation channel elevation is -34 feet mean lower low water (MLLW) Multiple deepening scenarios are being assessed (-51 -53 -55 feet andor -57 feet MLLW) The estimated volumes of sediment that may be suitable for open-water disposal andor beneficial reuse for each deepening scenario will ultimately be incorporated into the Feasibility Study

2 SAMPLING METHODS
Sampling was conducted in accordance with the DMMP-approved QAPP (Anchor QEA 2015) The QAPP provides the sample design target sampling locations procedures for sample collection and processing data QC and data reporting requirements Any sampling method deviations from the QAPP are discussed in this section
The QAPP sampling plan included 23 sediment core stations within the boundary of the WW Sediment Operable Unit (OU) and the WW navigation channel (Figure 2) A total of 27 cores were collected from these locations by vibracore collection method Cores were transported to Analytical Resources Inc (ARI) for processing and physical characterization and then submitted for analysis Daily field activity is documented in Appendix A
21 Sampling Vessel Navigation and Positioning
Sampling was conducted aboard the research vessel (RV) Nancy Ann operated by subcontractor Marine Sampling Services using a vibracorer A differential global positioning system (DGPS) unit located on the top of the vibracore A-frame was used for positioning The DGPS was connected to a computer with software allowing the vessel operator to access the US Coast Guard differential signal from Seattle Washington for positioning The software was used to navigate to the proposed sampling stations and record the actual sampling position at the time of sampling Coordinates were recorded digitally and on core collection field logs in latitude and longitude as decimal minutes to the fourth decimal place using the North American Datum of 1983 (NAD83)
A fathometer mounted on the bow of RV Nancy Ann was used to measure depth Water depth was taken prior to lowering the vibracore to match station depth with the anticipated mudline to capture sediment from each theoretical dredge scenario described in the QAPP At each sampling station water depth (to the nearest tenth of a foot) was recorded on core collection logs (Appendix A) Predicted tide height based on National Oceanic and Atmospheric Administration (NOAA) predictions for Lockheed Shipyard were used to calculate mudline elevation in MLLW by multiplying the water depth by -1 then adding the predicted tidal elevation at the time of collection Prior to core processing preliminary tide measurements from NOAA were used to recalculate the actual mudline elevations used to

Sampling Methods
determine sample intervals in core processing These calculations can be found on the core collection logs
Twice-daily DGPS horizontal positioning and fathometer accuracy checks were performed at a piling at the southwestern corner of the Harbor Island Marina pier DGPS latitude and longitude readings were taken at a stationary piling at the marina before and after sampling each day Coordinates were recorded and compared to one another to assess DGPS precision throughout the sampling day and during the sampling effort All DGPS measurements were within plusmn179 feet of each other A lead line was used to measure depth and compared with the fathometer reading All lead line and fathometer mudline elevation measurements were within plusmn04 foot of each other
22 Core Collection
Sample cores from 23 discrete sampling stations were collected by vibracore on February 2 through 5 2015 Target and actual core locations are displayed in Figure 2 To obtain sufficient material for potential bioassay testing two cores were collected at each of four predetermined sample stations Actual core locations date collection time and mudline elevation are provided in Table 1
Table 1 also shows core drive penetration recovery measurement and percent recovery All accepted cores achieved the required penetration of 75 However not all cores were accepted on the first attempt One or more attempts were made at three locations (WWD01 WWD04 and WWD05) before acceptable cores were collected A brief description of coring attempts at these three locations is provided below
bull Station WWD01 required eight attempts to get an acceptable core Three attempts on February 2 2015 failed due to poor or no recovery when hard material at approximately 8 to 10 feet below mudline separated the nose of the aluminum core from the sample tube and resulted in loss of material from the core during pull-out The station was attempted again on February 5 2015 Poor or no recovery was encountered twice more due to loss of the nose Two more attempts encountered a steep grade on the bottom which caused the vibracore apparatus to tip with no sediment collected The target drive penetration was then decreased from 15 feet to
Field Investigation Report August 2015 West Waterway Sediment Characterization 4 110003-0102
Sampling Methods
10 feet to avoid driving through the obstruction and the final eighth core attempt was acceptable
bull Station WWD04 required two attempts The first attempt had zero recovery after losing the nose on a solid surface during pull-out The sample station was moved 108 feet southwest from the target location and the second attempt was acceptable
bull Station WWD05 required two attempts In the first attempt the vibracore unit tipped over after freefall was initiated This core attempt was rejected but a second attempt was acceptable
Most samples were within 10 feet of the proposed location with some exceptions Circumstances related to the movement of samples WWD01 and WWD04 are explained above Other modifications are described below
bull WWD19 was moved 287 feet north to obtain the proposed sample mudline elevation bull WWD21 was relocated 211 feet northeast to obtain the proposed sample mudline
elevation bull WWD22 was relocated 506 feet southwest in order to maintain spatial variation in
sampling The Port and USACE recommended moving this sample bull WWD23 was relocated because it was obstructed by a dry dock After consultation
with the Port and USACE the sample station was moved 1126 feet southwest
The mudline elevation at sample stations was within plusmn15 feet of the target mudline elevation with the exception of WWD23 which was 56 feet deeper than the target mudline of -45 feet MLLW As explained above this sample location was obstructed by the dry dock and USACE approved moving the station and the change in mudline elevation
23 Sample Processing
Sample processing was conducted in accordance with the QAPP in order to classify distinct layers of sediment for analysis and judgment of potential disposal suitability At the end of each sampling day the cores were transferred to ARI and held upright at 4degC until processing Processing began on February 3 2015 and concluded on February 9 2015
Field Investigation Report August 2015 West Waterway Sediment Characterization 5 110003-0102
Sampling Methods
When processed the core caps were removed and the core was cut longitudinally using a circular saw Core segments were placed end-to-end from top to bottom to show the entire core length for photographing and sample-splitting The core was split with decontaminated stainless steel knives or spatulas into two halves for sampling The sulfides samples were collected from one-half of the core immediately after splitting placed in jars with 5 milliliters of 2-Normal zinc acetate per 30 grams and shaken vigorously to preserve the samples
Prior to further sampling field staff re-measured cores and delineated sampling intervals based on preliminary tide data from NOAA All cores were logged for major lithological features classified according to the Unified Soil Classification System and photographed (Appendix A) Sample intervals were based on recovered depth not corrected for length based on core recovery Elevations of core intervals (MLLW) and sample depths relative to mudline are shown in Table 2 Samples were placed in decontaminated stainless steel bowls and mixed until homogenous in color and texture using a decontaminated stainless steel mixing spoon The sediment was then spooned into laboratory-supplied jars for analyses A chain-of-custody form was logged by the processing staff and relinquished to the laboratory staff (Appendix A) Fifty-seven samples were collected and submitted for analysis or sample archive A complete sample inventory including represented intervals and requested chemistry is shown in Table 3
Four stations required two co-located cores to achieve sufficient volume for bioassay archives Co-located cores differed by less than plusmn02 foot in mudline elevation with the exception of WWD02 which differed by 22 feet To adjust for the 22-foot difference in this sample the core closest to the target mudline elevation was deemed the primary core and intervals in the second core were adjusted to match the elevations of sampled strata from the primary core This decision was supported by lithography and physical sediment characteristics and was approved by USACE
24 Sediment Grab Collection
To collect a reference sample for comparison to samples submitted for biological testing a sediment grab sample was collected from a DMMP-approved reference area in Carr Inlet
Field Investigation Report August 2015 West Waterway Sediment Characterization 6 110003-0102
Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate

Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

1 INTRODUCTION
This Field Investigation Report presents the results of the West Waterway (WW) Sediment Characterization Study conducted in Seattle Washington (Figure 1) Sediment samples were collected and analyzed in accordance with the Dredged Material Management Program (DMMP)-approved Quality Assurance Project Plan (QAPP Anchor QEA 2015) Bioassay samples were analyzed in accordance with the Port of Seattlersquos (Portrsquos) DMMP-approved Terminal 5 Sampling and Analysis Plan (SAP Hart Crowser 2014) and the latest DMMP guidance (DMMO 2014)
The QAPP was written to ensure that collection sampling and analysis of sediment followed DMMP guidance to estimate potential suitability of dredged sediment for open-water disposal but was not intended to provide a full characterization to support a suitability determination
Specific information provided in this Field Investigation Report includes the following
bull Summary of sampling activities bull Data quality assessments bull Deviations from the QAPP bull Analytical and biological results compared to DMMP criteria
11 Project Description
The study was conducted by the Port for the US Army Corps of Engineers (USACE) in support of the Seattle Harbor Navigation Improvement Feasibility Study to analyze and evaluate navigation improvements to the WW The objective of the study was to estimate the potential suitability of subtidal dredged materials for open-water disposal andor beneficial reuse
The current authorized navigation channel elevation is -34 feet mean lower low water (MLLW) Multiple deepening scenarios are being assessed (-51 -53 -55 feet andor -57 feet MLLW) The estimated volumes of sediment that may be suitable for open-water disposal andor beneficial reuse for each deepening scenario will ultimately be incorporated into the Feasibility Study

2 SAMPLING METHODS
Sampling was conducted in accordance with the DMMP-approved QAPP (Anchor QEA 2015) The QAPP provides the sample design target sampling locations procedures for sample collection and processing data QC and data reporting requirements Any sampling method deviations from the QAPP are discussed in this section
The QAPP sampling plan included 23 sediment core stations within the boundary of the WW Sediment Operable Unit (OU) and the WW navigation channel (Figure 2) A total of 27 cores were collected from these locations by vibracore collection method Cores were transported to Analytical Resources Inc (ARI) for processing and physical characterization and then submitted for analysis Daily field activity is documented in Appendix A
21 Sampling Vessel Navigation and Positioning
Sampling was conducted aboard the research vessel (RV) Nancy Ann operated by subcontractor Marine Sampling Services using a vibracorer A differential global positioning system (DGPS) unit located on the top of the vibracore A-frame was used for positioning The DGPS was connected to a computer with software allowing the vessel operator to access the US Coast Guard differential signal from Seattle Washington for positioning The software was used to navigate to the proposed sampling stations and record the actual sampling position at the time of sampling Coordinates were recorded digitally and on core collection field logs in latitude and longitude as decimal minutes to the fourth decimal place using the North American Datum of 1983 (NAD83)
A fathometer mounted on the bow of RV Nancy Ann was used to measure depth Water depth was taken prior to lowering the vibracore to match station depth with the anticipated mudline to capture sediment from each theoretical dredge scenario described in the QAPP At each sampling station water depth (to the nearest tenth of a foot) was recorded on core collection logs (Appendix A) Predicted tide height based on National Oceanic and Atmospheric Administration (NOAA) predictions for Lockheed Shipyard were used to calculate mudline elevation in MLLW by multiplying the water depth by -1 then adding the predicted tidal elevation at the time of collection Prior to core processing preliminary tide measurements from NOAA were used to recalculate the actual mudline elevations used to

Sampling Methods
determine sample intervals in core processing These calculations can be found on the core collection logs
Twice-daily DGPS horizontal positioning and fathometer accuracy checks were performed at a piling at the southwestern corner of the Harbor Island Marina pier DGPS latitude and longitude readings were taken at a stationary piling at the marina before and after sampling each day Coordinates were recorded and compared to one another to assess DGPS precision throughout the sampling day and during the sampling effort All DGPS measurements were within plusmn179 feet of each other A lead line was used to measure depth and compared with the fathometer reading All lead line and fathometer mudline elevation measurements were within plusmn04 foot of each other
22 Core Collection
Sample cores from 23 discrete sampling stations were collected by vibracore on February 2 through 5 2015 Target and actual core locations are displayed in Figure 2 To obtain sufficient material for potential bioassay testing two cores were collected at each of four predetermined sample stations Actual core locations date collection time and mudline elevation are provided in Table 1
Table 1 also shows core drive penetration recovery measurement and percent recovery All accepted cores achieved the required penetration of 75 However not all cores were accepted on the first attempt One or more attempts were made at three locations (WWD01 WWD04 and WWD05) before acceptable cores were collected A brief description of coring attempts at these three locations is provided below
bull Station WWD01 required eight attempts to get an acceptable core Three attempts on February 2 2015 failed due to poor or no recovery when hard material at approximately 8 to 10 feet below mudline separated the nose of the aluminum core from the sample tube and resulted in loss of material from the core during pull-out The station was attempted again on February 5 2015 Poor or no recovery was encountered twice more due to loss of the nose Two more attempts encountered a steep grade on the bottom which caused the vibracore apparatus to tip with no sediment collected The target drive penetration was then decreased from 15 feet to
Field Investigation Report August 2015 West Waterway Sediment Characterization 4 110003-0102
Sampling Methods
10 feet to avoid driving through the obstruction and the final eighth core attempt was acceptable
bull Station WWD04 required two attempts The first attempt had zero recovery after losing the nose on a solid surface during pull-out The sample station was moved 108 feet southwest from the target location and the second attempt was acceptable
bull Station WWD05 required two attempts In the first attempt the vibracore unit tipped over after freefall was initiated This core attempt was rejected but a second attempt was acceptable
Most samples were within 10 feet of the proposed location with some exceptions Circumstances related to the movement of samples WWD01 and WWD04 are explained above Other modifications are described below
bull WWD19 was moved 287 feet north to obtain the proposed sample mudline elevation bull WWD21 was relocated 211 feet northeast to obtain the proposed sample mudline
elevation bull WWD22 was relocated 506 feet southwest in order to maintain spatial variation in
sampling The Port and USACE recommended moving this sample bull WWD23 was relocated because it was obstructed by a dry dock After consultation
with the Port and USACE the sample station was moved 1126 feet southwest
The mudline elevation at sample stations was within plusmn15 feet of the target mudline elevation with the exception of WWD23 which was 56 feet deeper than the target mudline of -45 feet MLLW As explained above this sample location was obstructed by the dry dock and USACE approved moving the station and the change in mudline elevation
23 Sample Processing
Sample processing was conducted in accordance with the QAPP in order to classify distinct layers of sediment for analysis and judgment of potential disposal suitability At the end of each sampling day the cores were transferred to ARI and held upright at 4degC until processing Processing began on February 3 2015 and concluded on February 9 2015
Field Investigation Report August 2015 West Waterway Sediment Characterization 5 110003-0102
Sampling Methods
When processed the core caps were removed and the core was cut longitudinally using a circular saw Core segments were placed end-to-end from top to bottom to show the entire core length for photographing and sample-splitting The core was split with decontaminated stainless steel knives or spatulas into two halves for sampling The sulfides samples were collected from one-half of the core immediately after splitting placed in jars with 5 milliliters of 2-Normal zinc acetate per 30 grams and shaken vigorously to preserve the samples
Prior to further sampling field staff re-measured cores and delineated sampling intervals based on preliminary tide data from NOAA All cores were logged for major lithological features classified according to the Unified Soil Classification System and photographed (Appendix A) Sample intervals were based on recovered depth not corrected for length based on core recovery Elevations of core intervals (MLLW) and sample depths relative to mudline are shown in Table 2 Samples were placed in decontaminated stainless steel bowls and mixed until homogenous in color and texture using a decontaminated stainless steel mixing spoon The sediment was then spooned into laboratory-supplied jars for analyses A chain-of-custody form was logged by the processing staff and relinquished to the laboratory staff (Appendix A) Fifty-seven samples were collected and submitted for analysis or sample archive A complete sample inventory including represented intervals and requested chemistry is shown in Table 3
Four stations required two co-located cores to achieve sufficient volume for bioassay archives Co-located cores differed by less than plusmn02 foot in mudline elevation with the exception of WWD02 which differed by 22 feet To adjust for the 22-foot difference in this sample the core closest to the target mudline elevation was deemed the primary core and intervals in the second core were adjusted to match the elevations of sampled strata from the primary core This decision was supported by lithography and physical sediment characteristics and was approved by USACE
24 Sediment Grab Collection
To collect a reference sample for comparison to samples submitted for biological testing a sediment grab sample was collected from a DMMP-approved reference area in Carr Inlet
Field Investigation Report August 2015 West Waterway Sediment Characterization 6 110003-0102
Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate

Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

1 INTRODUCTION
This Field Investigation Report presents the results of the West Waterway (WW) Sediment Characterization Study conducted in Seattle Washington (Figure 1) Sediment samples were collected and analyzed in accordance with the Dredged Material Management Program (DMMP)-approved Quality Assurance Project Plan (QAPP Anchor QEA 2015) Bioassay samples were analyzed in accordance with the Port of Seattlersquos (Portrsquos) DMMP-approved Terminal 5 Sampling and Analysis Plan (SAP Hart Crowser 2014) and the latest DMMP guidance (DMMO 2014)
The QAPP was written to ensure that collection sampling and analysis of sediment followed DMMP guidance to estimate potential suitability of dredged sediment for open-water disposal but was not intended to provide a full characterization to support a suitability determination
Specific information provided in this Field Investigation Report includes the following
bull Summary of sampling activities bull Data quality assessments bull Deviations from the QAPP bull Analytical and biological results compared to DMMP criteria
11 Project Description
The study was conducted by the Port for the US Army Corps of Engineers (USACE) in support of the Seattle Harbor Navigation Improvement Feasibility Study to analyze and evaluate navigation improvements to the WW The objective of the study was to estimate the potential suitability of subtidal dredged materials for open-water disposal andor beneficial reuse
The current authorized navigation channel elevation is -34 feet mean lower low water (MLLW) Multiple deepening scenarios are being assessed (-51 -53 -55 feet andor -57 feet MLLW) The estimated volumes of sediment that may be suitable for open-water disposal andor beneficial reuse for each deepening scenario will ultimately be incorporated into the Feasibility Study

2 SAMPLING METHODS
Sampling was conducted in accordance with the DMMP-approved QAPP (Anchor QEA 2015) The QAPP provides the sample design target sampling locations procedures for sample collection and processing data QC and data reporting requirements Any sampling method deviations from the QAPP are discussed in this section
The QAPP sampling plan included 23 sediment core stations within the boundary of the WW Sediment Operable Unit (OU) and the WW navigation channel (Figure 2) A total of 27 cores were collected from these locations by vibracore collection method Cores were transported to Analytical Resources Inc (ARI) for processing and physical characterization and then submitted for analysis Daily field activity is documented in Appendix A
21 Sampling Vessel Navigation and Positioning
Sampling was conducted aboard the research vessel (RV) Nancy Ann operated by subcontractor Marine Sampling Services using a vibracorer A differential global positioning system (DGPS) unit located on the top of the vibracore A-frame was used for positioning The DGPS was connected to a computer with software allowing the vessel operator to access the US Coast Guard differential signal from Seattle Washington for positioning The software was used to navigate to the proposed sampling stations and record the actual sampling position at the time of sampling Coordinates were recorded digitally and on core collection field logs in latitude and longitude as decimal minutes to the fourth decimal place using the North American Datum of 1983 (NAD83)
A fathometer mounted on the bow of RV Nancy Ann was used to measure depth Water depth was taken prior to lowering the vibracore to match station depth with the anticipated mudline to capture sediment from each theoretical dredge scenario described in the QAPP At each sampling station water depth (to the nearest tenth of a foot) was recorded on core collection logs (Appendix A) Predicted tide height based on National Oceanic and Atmospheric Administration (NOAA) predictions for Lockheed Shipyard were used to calculate mudline elevation in MLLW by multiplying the water depth by -1 then adding the predicted tidal elevation at the time of collection Prior to core processing preliminary tide measurements from NOAA were used to recalculate the actual mudline elevations used to

Sampling Methods
determine sample intervals in core processing These calculations can be found on the core collection logs
Twice-daily DGPS horizontal positioning and fathometer accuracy checks were performed at a piling at the southwestern corner of the Harbor Island Marina pier DGPS latitude and longitude readings were taken at a stationary piling at the marina before and after sampling each day Coordinates were recorded and compared to one another to assess DGPS precision throughout the sampling day and during the sampling effort All DGPS measurements were within plusmn179 feet of each other A lead line was used to measure depth and compared with the fathometer reading All lead line and fathometer mudline elevation measurements were within plusmn04 foot of each other
22 Core Collection
Sample cores from 23 discrete sampling stations were collected by vibracore on February 2 through 5 2015 Target and actual core locations are displayed in Figure 2 To obtain sufficient material for potential bioassay testing two cores were collected at each of four predetermined sample stations Actual core locations date collection time and mudline elevation are provided in Table 1
Table 1 also shows core drive penetration recovery measurement and percent recovery All accepted cores achieved the required penetration of 75 However not all cores were accepted on the first attempt One or more attempts were made at three locations (WWD01 WWD04 and WWD05) before acceptable cores were collected A brief description of coring attempts at these three locations is provided below
bull Station WWD01 required eight attempts to get an acceptable core Three attempts on February 2 2015 failed due to poor or no recovery when hard material at approximately 8 to 10 feet below mudline separated the nose of the aluminum core from the sample tube and resulted in loss of material from the core during pull-out The station was attempted again on February 5 2015 Poor or no recovery was encountered twice more due to loss of the nose Two more attempts encountered a steep grade on the bottom which caused the vibracore apparatus to tip with no sediment collected The target drive penetration was then decreased from 15 feet to
Field Investigation Report August 2015 West Waterway Sediment Characterization 4 110003-0102
Sampling Methods
10 feet to avoid driving through the obstruction and the final eighth core attempt was acceptable
bull Station WWD04 required two attempts The first attempt had zero recovery after losing the nose on a solid surface during pull-out The sample station was moved 108 feet southwest from the target location and the second attempt was acceptable
bull Station WWD05 required two attempts In the first attempt the vibracore unit tipped over after freefall was initiated This core attempt was rejected but a second attempt was acceptable
Most samples were within 10 feet of the proposed location with some exceptions Circumstances related to the movement of samples WWD01 and WWD04 are explained above Other modifications are described below
bull WWD19 was moved 287 feet north to obtain the proposed sample mudline elevation bull WWD21 was relocated 211 feet northeast to obtain the proposed sample mudline
elevation bull WWD22 was relocated 506 feet southwest in order to maintain spatial variation in
sampling The Port and USACE recommended moving this sample bull WWD23 was relocated because it was obstructed by a dry dock After consultation
with the Port and USACE the sample station was moved 1126 feet southwest
The mudline elevation at sample stations was within plusmn15 feet of the target mudline elevation with the exception of WWD23 which was 56 feet deeper than the target mudline of -45 feet MLLW As explained above this sample location was obstructed by the dry dock and USACE approved moving the station and the change in mudline elevation
23 Sample Processing
Sample processing was conducted in accordance with the QAPP in order to classify distinct layers of sediment for analysis and judgment of potential disposal suitability At the end of each sampling day the cores were transferred to ARI and held upright at 4degC until processing Processing began on February 3 2015 and concluded on February 9 2015
Field Investigation Report August 2015 West Waterway Sediment Characterization 5 110003-0102
Sampling Methods
When processed the core caps were removed and the core was cut longitudinally using a circular saw Core segments were placed end-to-end from top to bottom to show the entire core length for photographing and sample-splitting The core was split with decontaminated stainless steel knives or spatulas into two halves for sampling The sulfides samples were collected from one-half of the core immediately after splitting placed in jars with 5 milliliters of 2-Normal zinc acetate per 30 grams and shaken vigorously to preserve the samples
Prior to further sampling field staff re-measured cores and delineated sampling intervals based on preliminary tide data from NOAA All cores were logged for major lithological features classified according to the Unified Soil Classification System and photographed (Appendix A) Sample intervals were based on recovered depth not corrected for length based on core recovery Elevations of core intervals (MLLW) and sample depths relative to mudline are shown in Table 2 Samples were placed in decontaminated stainless steel bowls and mixed until homogenous in color and texture using a decontaminated stainless steel mixing spoon The sediment was then spooned into laboratory-supplied jars for analyses A chain-of-custody form was logged by the processing staff and relinquished to the laboratory staff (Appendix A) Fifty-seven samples were collected and submitted for analysis or sample archive A complete sample inventory including represented intervals and requested chemistry is shown in Table 3
Four stations required two co-located cores to achieve sufficient volume for bioassay archives Co-located cores differed by less than plusmn02 foot in mudline elevation with the exception of WWD02 which differed by 22 feet To adjust for the 22-foot difference in this sample the core closest to the target mudline elevation was deemed the primary core and intervals in the second core were adjusted to match the elevations of sampled strata from the primary core This decision was supported by lithography and physical sediment characteristics and was approved by USACE
24 Sediment Grab Collection
To collect a reference sample for comparison to samples submitted for biological testing a sediment grab sample was collected from a DMMP-approved reference area in Carr Inlet
Field Investigation Report August 2015 West Waterway Sediment Characterization 6 110003-0102
Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate

Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically

Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

2 SAMPLING METHODS
Sampling was conducted in accordance with the DMMP-approved QAPP (Anchor QEA 2015) The QAPP provides the sample design target sampling locations procedures for sample collection and processing data QC and data reporting requirements Any sampling method deviations from the QAPP are discussed in this section
The QAPP sampling plan included 23 sediment core stations within the boundary of the WW Sediment Operable Unit (OU) and the WW navigation channel (Figure 2) A total of 27 cores were collected from these locations by vibracore collection method Cores were transported to Analytical Resources Inc (ARI) for processing and physical characterization and then submitted for analysis Daily field activity is documented in Appendix A
21 Sampling Vessel Navigation and Positioning
Sampling was conducted aboard the research vessel (RV) Nancy Ann operated by subcontractor Marine Sampling Services using a vibracorer A differential global positioning system (DGPS) unit located on the top of the vibracore A-frame was used for positioning The DGPS was connected to a computer with software allowing the vessel operator to access the US Coast Guard differential signal from Seattle Washington for positioning The software was used to navigate to the proposed sampling stations and record the actual sampling position at the time of sampling Coordinates were recorded digitally and on core collection field logs in latitude and longitude as decimal minutes to the fourth decimal place using the North American Datum of 1983 (NAD83)
A fathometer mounted on the bow of RV Nancy Ann was used to measure depth Water depth was taken prior to lowering the vibracore to match station depth with the anticipated mudline to capture sediment from each theoretical dredge scenario described in the QAPP At each sampling station water depth (to the nearest tenth of a foot) was recorded on core collection logs (Appendix A) Predicted tide height based on National Oceanic and Atmospheric Administration (NOAA) predictions for Lockheed Shipyard were used to calculate mudline elevation in MLLW by multiplying the water depth by -1 then adding the predicted tidal elevation at the time of collection Prior to core processing preliminary tide measurements from NOAA were used to recalculate the actual mudline elevations used to
Field Investigation Report August 2015 West Waterway Sediment Characterization 3 110003-0102
Sampling Methods
determine sample intervals in core processing These calculations can be found on the core collection logs
Twice-daily DGPS horizontal positioning and fathometer accuracy checks were performed at a piling at the southwestern corner of the Harbor Island Marina pier DGPS latitude and longitude readings were taken at a stationary piling at the marina before and after sampling each day Coordinates were recorded and compared to one another to assess DGPS precision throughout the sampling day and during the sampling effort All DGPS measurements were within plusmn179 feet of each other A lead line was used to measure depth and compared with the fathometer reading All lead line and fathometer mudline elevation measurements were within plusmn04 foot of each other
22 Core Collection
Sample cores from 23 discrete sampling stations were collected by vibracore on February 2 through 5 2015 Target and actual core locations are displayed in Figure 2 To obtain sufficient material for potential bioassay testing two cores were collected at each of four predetermined sample stations Actual core locations date collection time and mudline elevation are provided in Table 1
Table 1 also shows core drive penetration recovery measurement and percent recovery All accepted cores achieved the required penetration of 75 However not all cores were accepted on the first attempt One or more attempts were made at three locations (WWD01 WWD04 and WWD05) before acceptable cores were collected A brief description of coring attempts at these three locations is provided below
bull Station WWD01 required eight attempts to get an acceptable core Three attempts on February 2 2015 failed due to poor or no recovery when hard material at approximately 8 to 10 feet below mudline separated the nose of the aluminum core from the sample tube and resulted in loss of material from the core during pull-out The station was attempted again on February 5 2015 Poor or no recovery was encountered twice more due to loss of the nose Two more attempts encountered a steep grade on the bottom which caused the vibracore apparatus to tip with no sediment collected The target drive penetration was then decreased from 15 feet to
Field Investigation Report August 2015 West Waterway Sediment Characterization 4 110003-0102
Sampling Methods
10 feet to avoid driving through the obstruction and the final eighth core attempt was acceptable
bull Station WWD04 required two attempts The first attempt had zero recovery after losing the nose on a solid surface during pull-out The sample station was moved 108 feet southwest from the target location and the second attempt was acceptable
bull Station WWD05 required two attempts In the first attempt the vibracore unit tipped over after freefall was initiated This core attempt was rejected but a second attempt was acceptable
Most samples were within 10 feet of the proposed location with some exceptions Circumstances related to the movement of samples WWD01 and WWD04 are explained above Other modifications are described below
bull WWD19 was moved 287 feet north to obtain the proposed sample mudline elevation bull WWD21 was relocated 211 feet northeast to obtain the proposed sample mudline
elevation bull WWD22 was relocated 506 feet southwest in order to maintain spatial variation in
sampling The Port and USACE recommended moving this sample bull WWD23 was relocated because it was obstructed by a dry dock After consultation
with the Port and USACE the sample station was moved 1126 feet southwest
The mudline elevation at sample stations was within plusmn15 feet of the target mudline elevation with the exception of WWD23 which was 56 feet deeper than the target mudline of -45 feet MLLW As explained above this sample location was obstructed by the dry dock and USACE approved moving the station and the change in mudline elevation
23 Sample Processing
Sample processing was conducted in accordance with the QAPP in order to classify distinct layers of sediment for analysis and judgment of potential disposal suitability At the end of each sampling day the cores were transferred to ARI and held upright at 4degC until processing Processing began on February 3 2015 and concluded on February 9 2015
Field Investigation Report August 2015 West Waterway Sediment Characterization 5 110003-0102
Sampling Methods
When processed the core caps were removed and the core was cut longitudinally using a circular saw Core segments were placed end-to-end from top to bottom to show the entire core length for photographing and sample-splitting The core was split with decontaminated stainless steel knives or spatulas into two halves for sampling The sulfides samples were collected from one-half of the core immediately after splitting placed in jars with 5 milliliters of 2-Normal zinc acetate per 30 grams and shaken vigorously to preserve the samples
Prior to further sampling field staff re-measured cores and delineated sampling intervals based on preliminary tide data from NOAA All cores were logged for major lithological features classified according to the Unified Soil Classification System and photographed (Appendix A) Sample intervals were based on recovered depth not corrected for length based on core recovery Elevations of core intervals (MLLW) and sample depths relative to mudline are shown in Table 2 Samples were placed in decontaminated stainless steel bowls and mixed until homogenous in color and texture using a decontaminated stainless steel mixing spoon The sediment was then spooned into laboratory-supplied jars for analyses A chain-of-custody form was logged by the processing staff and relinquished to the laboratory staff (Appendix A) Fifty-seven samples were collected and submitted for analysis or sample archive A complete sample inventory including represented intervals and requested chemistry is shown in Table 3
Four stations required two co-located cores to achieve sufficient volume for bioassay archives Co-located cores differed by less than plusmn02 foot in mudline elevation with the exception of WWD02 which differed by 22 feet To adjust for the 22-foot difference in this sample the core closest to the target mudline elevation was deemed the primary core and intervals in the second core were adjusted to match the elevations of sampled strata from the primary core This decision was supported by lithography and physical sediment characteristics and was approved by USACE
24 Sediment Grab Collection
To collect a reference sample for comparison to samples submitted for biological testing a sediment grab sample was collected from a DMMP-approved reference area in Carr Inlet
Field Investigation Report August 2015 West Waterway Sediment Characterization 6 110003-0102
Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate
Field Investigation Report August 2015 West Waterway Sediment Characterization 8 110003-0102
Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

2 SAMPLING METHODS
Sampling was conducted in accordance with the DMMP-approved QAPP (Anchor QEA 2015) The QAPP provides the sample design target sampling locations procedures for sample collection and processing data QC and data reporting requirements Any sampling method deviations from the QAPP are discussed in this section
The QAPP sampling plan included 23 sediment core stations within the boundary of the WW Sediment Operable Unit (OU) and the WW navigation channel (Figure 2) A total of 27 cores were collected from these locations by vibracore collection method Cores were transported to Analytical Resources Inc (ARI) for processing and physical characterization and then submitted for analysis Daily field activity is documented in Appendix A
21 Sampling Vessel Navigation and Positioning
Sampling was conducted aboard the research vessel (RV) Nancy Ann operated by subcontractor Marine Sampling Services using a vibracorer A differential global positioning system (DGPS) unit located on the top of the vibracore A-frame was used for positioning The DGPS was connected to a computer with software allowing the vessel operator to access the US Coast Guard differential signal from Seattle Washington for positioning The software was used to navigate to the proposed sampling stations and record the actual sampling position at the time of sampling Coordinates were recorded digitally and on core collection field logs in latitude and longitude as decimal minutes to the fourth decimal place using the North American Datum of 1983 (NAD83)
A fathometer mounted on the bow of RV Nancy Ann was used to measure depth Water depth was taken prior to lowering the vibracore to match station depth with the anticipated mudline to capture sediment from each theoretical dredge scenario described in the QAPP At each sampling station water depth (to the nearest tenth of a foot) was recorded on core collection logs (Appendix A) Predicted tide height based on National Oceanic and Atmospheric Administration (NOAA) predictions for Lockheed Shipyard were used to calculate mudline elevation in MLLW by multiplying the water depth by -1 then adding the predicted tidal elevation at the time of collection Prior to core processing preliminary tide measurements from NOAA were used to recalculate the actual mudline elevations used to
Field Investigation Report August 2015 West Waterway Sediment Characterization 3 110003-0102
Sampling Methods
determine sample intervals in core processing These calculations can be found on the core collection logs
Twice-daily DGPS horizontal positioning and fathometer accuracy checks were performed at a piling at the southwestern corner of the Harbor Island Marina pier DGPS latitude and longitude readings were taken at a stationary piling at the marina before and after sampling each day Coordinates were recorded and compared to one another to assess DGPS precision throughout the sampling day and during the sampling effort All DGPS measurements were within plusmn179 feet of each other A lead line was used to measure depth and compared with the fathometer reading All lead line and fathometer mudline elevation measurements were within plusmn04 foot of each other
22 Core Collection
Sample cores from 23 discrete sampling stations were collected by vibracore on February 2 through 5 2015 Target and actual core locations are displayed in Figure 2 To obtain sufficient material for potential bioassay testing two cores were collected at each of four predetermined sample stations Actual core locations date collection time and mudline elevation are provided in Table 1
Table 1 also shows core drive penetration recovery measurement and percent recovery All accepted cores achieved the required penetration of 75 However not all cores were accepted on the first attempt One or more attempts were made at three locations (WWD01 WWD04 and WWD05) before acceptable cores were collected A brief description of coring attempts at these three locations is provided below
bull Station WWD01 required eight attempts to get an acceptable core Three attempts on February 2 2015 failed due to poor or no recovery when hard material at approximately 8 to 10 feet below mudline separated the nose of the aluminum core from the sample tube and resulted in loss of material from the core during pull-out The station was attempted again on February 5 2015 Poor or no recovery was encountered twice more due to loss of the nose Two more attempts encountered a steep grade on the bottom which caused the vibracore apparatus to tip with no sediment collected The target drive penetration was then decreased from 15 feet to
Field Investigation Report August 2015 West Waterway Sediment Characterization 4 110003-0102
Sampling Methods
10 feet to avoid driving through the obstruction and the final eighth core attempt was acceptable
bull Station WWD04 required two attempts The first attempt had zero recovery after losing the nose on a solid surface during pull-out The sample station was moved 108 feet southwest from the target location and the second attempt was acceptable
bull Station WWD05 required two attempts In the first attempt the vibracore unit tipped over after freefall was initiated This core attempt was rejected but a second attempt was acceptable
Most samples were within 10 feet of the proposed location with some exceptions Circumstances related to the movement of samples WWD01 and WWD04 are explained above Other modifications are described below
bull WWD19 was moved 287 feet north to obtain the proposed sample mudline elevation bull WWD21 was relocated 211 feet northeast to obtain the proposed sample mudline
elevation bull WWD22 was relocated 506 feet southwest in order to maintain spatial variation in
sampling The Port and USACE recommended moving this sample bull WWD23 was relocated because it was obstructed by a dry dock After consultation
with the Port and USACE the sample station was moved 1126 feet southwest
The mudline elevation at sample stations was within plusmn15 feet of the target mudline elevation with the exception of WWD23 which was 56 feet deeper than the target mudline of -45 feet MLLW As explained above this sample location was obstructed by the dry dock and USACE approved moving the station and the change in mudline elevation
23 Sample Processing
Sample processing was conducted in accordance with the QAPP in order to classify distinct layers of sediment for analysis and judgment of potential disposal suitability At the end of each sampling day the cores were transferred to ARI and held upright at 4degC until processing Processing began on February 3 2015 and concluded on February 9 2015
Field Investigation Report August 2015 West Waterway Sediment Characterization 5 110003-0102
Sampling Methods
When processed the core caps were removed and the core was cut longitudinally using a circular saw Core segments were placed end-to-end from top to bottom to show the entire core length for photographing and sample-splitting The core was split with decontaminated stainless steel knives or spatulas into two halves for sampling The sulfides samples were collected from one-half of the core immediately after splitting placed in jars with 5 milliliters of 2-Normal zinc acetate per 30 grams and shaken vigorously to preserve the samples
Prior to further sampling field staff re-measured cores and delineated sampling intervals based on preliminary tide data from NOAA All cores were logged for major lithological features classified according to the Unified Soil Classification System and photographed (Appendix A) Sample intervals were based on recovered depth not corrected for length based on core recovery Elevations of core intervals (MLLW) and sample depths relative to mudline are shown in Table 2 Samples were placed in decontaminated stainless steel bowls and mixed until homogenous in color and texture using a decontaminated stainless steel mixing spoon The sediment was then spooned into laboratory-supplied jars for analyses A chain-of-custody form was logged by the processing staff and relinquished to the laboratory staff (Appendix A) Fifty-seven samples were collected and submitted for analysis or sample archive A complete sample inventory including represented intervals and requested chemistry is shown in Table 3
Four stations required two co-located cores to achieve sufficient volume for bioassay archives Co-located cores differed by less than plusmn02 foot in mudline elevation with the exception of WWD02 which differed by 22 feet To adjust for the 22-foot difference in this sample the core closest to the target mudline elevation was deemed the primary core and intervals in the second core were adjusted to match the elevations of sampled strata from the primary core This decision was supported by lithography and physical sediment characteristics and was approved by USACE
24 Sediment Grab Collection
To collect a reference sample for comparison to samples submitted for biological testing a sediment grab sample was collected from a DMMP-approved reference area in Carr Inlet
Field Investigation Report August 2015 West Waterway Sediment Characterization 6 110003-0102
Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate

Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically

Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

determine sample intervals in core processing These calculations can be found on the core collection logs
Twice-daily DGPS horizontal positioning and fathometer accuracy checks were performed at a piling at the southwestern corner of the Harbor Island Marina pier DGPS latitude and longitude readings were taken at a stationary piling at the marina before and after sampling each day Coordinates were recorded and compared to one another to assess DGPS precision throughout the sampling day and during the sampling effort All DGPS measurements were within plusmn179 feet of each other A lead line was used to measure depth and compared with the fathometer reading All lead line and fathometer mudline elevation measurements were within plusmn04 foot of each other
22 Core Collection
Sample cores from 23 discrete sampling stations were collected by vibracore on February 2 through 5 2015 Target and actual core locations are displayed in Figure 2 To obtain sufficient material for potential bioassay testing two cores were collected at each of four predetermined sample stations Actual core locations date collection time and mudline elevation are provided in Table 1
Table 1 also shows core drive penetration recovery measurement and percent recovery All accepted cores achieved the required penetration of 75 However not all cores were accepted on the first attempt One or more attempts were made at three locations (WWD01 WWD04 and WWD05) before acceptable cores were collected A brief description of coring attempts at these three locations is provided below
bull Station WWD01 required eight attempts to get an acceptable core Three attempts on February 2 2015 failed due to poor or no recovery when hard material at approximately 8 to 10 feet below mudline separated the nose of the aluminum core from the sample tube and resulted in loss of material from the core during pull-out The station was attempted again on February 5 2015 Poor or no recovery was encountered twice more due to loss of the nose Two more attempts encountered a steep grade on the bottom which caused the vibracore apparatus to tip with no sediment collected The target drive penetration was then decreased from 15 feet to

Sampling Methods
10 feet to avoid driving through the obstruction and the final eighth core attempt was acceptable
bull Station WWD04 required two attempts The first attempt had zero recovery after losing the nose on a solid surface during pull-out The sample station was moved 108 feet southwest from the target location and the second attempt was acceptable
bull Station WWD05 required two attempts In the first attempt the vibracore unit tipped over after freefall was initiated This core attempt was rejected but a second attempt was acceptable
Most samples were within 10 feet of the proposed location with some exceptions Circumstances related to the movement of samples WWD01 and WWD04 are explained above Other modifications are described below
bull WWD19 was moved 287 feet north to obtain the proposed sample mudline elevation bull WWD21 was relocated 211 feet northeast to obtain the proposed sample mudline
elevation bull WWD22 was relocated 506 feet southwest in order to maintain spatial variation in
sampling The Port and USACE recommended moving this sample bull WWD23 was relocated because it was obstructed by a dry dock After consultation
with the Port and USACE the sample station was moved 1126 feet southwest
The mudline elevation at sample stations was within plusmn15 feet of the target mudline elevation with the exception of WWD23 which was 56 feet deeper than the target mudline of -45 feet MLLW As explained above this sample location was obstructed by the dry dock and USACE approved moving the station and the change in mudline elevation
23 Sample Processing
Sample processing was conducted in accordance with the QAPP in order to classify distinct layers of sediment for analysis and judgment of potential disposal suitability At the end of each sampling day the cores were transferred to ARI and held upright at 4degC until processing Processing began on February 3 2015 and concluded on February 9 2015
Field Investigation Report August 2015 West Waterway Sediment Characterization 5 110003-0102
Sampling Methods
When processed the core caps were removed and the core was cut longitudinally using a circular saw Core segments were placed end-to-end from top to bottom to show the entire core length for photographing and sample-splitting The core was split with decontaminated stainless steel knives or spatulas into two halves for sampling The sulfides samples were collected from one-half of the core immediately after splitting placed in jars with 5 milliliters of 2-Normal zinc acetate per 30 grams and shaken vigorously to preserve the samples
Prior to further sampling field staff re-measured cores and delineated sampling intervals based on preliminary tide data from NOAA All cores were logged for major lithological features classified according to the Unified Soil Classification System and photographed (Appendix A) Sample intervals were based on recovered depth not corrected for length based on core recovery Elevations of core intervals (MLLW) and sample depths relative to mudline are shown in Table 2 Samples were placed in decontaminated stainless steel bowls and mixed until homogenous in color and texture using a decontaminated stainless steel mixing spoon The sediment was then spooned into laboratory-supplied jars for analyses A chain-of-custody form was logged by the processing staff and relinquished to the laboratory staff (Appendix A) Fifty-seven samples were collected and submitted for analysis or sample archive A complete sample inventory including represented intervals and requested chemistry is shown in Table 3
Four stations required two co-located cores to achieve sufficient volume for bioassay archives Co-located cores differed by less than plusmn02 foot in mudline elevation with the exception of WWD02 which differed by 22 feet To adjust for the 22-foot difference in this sample the core closest to the target mudline elevation was deemed the primary core and intervals in the second core were adjusted to match the elevations of sampled strata from the primary core This decision was supported by lithography and physical sediment characteristics and was approved by USACE
24 Sediment Grab Collection
To collect a reference sample for comparison to samples submitted for biological testing a sediment grab sample was collected from a DMMP-approved reference area in Carr Inlet
Field Investigation Report August 2015 West Waterway Sediment Characterization 6 110003-0102
Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate

Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)

Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

Sampling Methods
10 feet to avoid driving through the obstruction and the final eighth core attempt was acceptable
bull Station WWD04 required two attempts The first attempt had zero recovery after losing the nose on a solid surface during pull-out The sample station was moved 108 feet southwest from the target location and the second attempt was acceptable
bull Station WWD05 required two attempts In the first attempt the vibracore unit tipped over after freefall was initiated This core attempt was rejected but a second attempt was acceptable
Most samples were within 10 feet of the proposed location with some exceptions Circumstances related to the movement of samples WWD01 and WWD04 are explained above Other modifications are described below
bull WWD19 was moved 287 feet north to obtain the proposed sample mudline elevation bull WWD21 was relocated 211 feet northeast to obtain the proposed sample mudline
elevation bull WWD22 was relocated 506 feet southwest in order to maintain spatial variation in
sampling The Port and USACE recommended moving this sample bull WWD23 was relocated because it was obstructed by a dry dock After consultation
with the Port and USACE the sample station was moved 1126 feet southwest
The mudline elevation at sample stations was within plusmn15 feet of the target mudline elevation with the exception of WWD23 which was 56 feet deeper than the target mudline of -45 feet MLLW As explained above this sample location was obstructed by the dry dock and USACE approved moving the station and the change in mudline elevation
23 Sample Processing
Sample processing was conducted in accordance with the QAPP in order to classify distinct layers of sediment for analysis and judgment of potential disposal suitability At the end of each sampling day the cores were transferred to ARI and held upright at 4degC until processing Processing began on February 3 2015 and concluded on February 9 2015
Field Investigation Report August 2015 West Waterway Sediment Characterization 5 110003-0102
Sampling Methods
When processed the core caps were removed and the core was cut longitudinally using a circular saw Core segments were placed end-to-end from top to bottom to show the entire core length for photographing and sample-splitting The core was split with decontaminated stainless steel knives or spatulas into two halves for sampling The sulfides samples were collected from one-half of the core immediately after splitting placed in jars with 5 milliliters of 2-Normal zinc acetate per 30 grams and shaken vigorously to preserve the samples
Prior to further sampling field staff re-measured cores and delineated sampling intervals based on preliminary tide data from NOAA All cores were logged for major lithological features classified according to the Unified Soil Classification System and photographed (Appendix A) Sample intervals were based on recovered depth not corrected for length based on core recovery Elevations of core intervals (MLLW) and sample depths relative to mudline are shown in Table 2 Samples were placed in decontaminated stainless steel bowls and mixed until homogenous in color and texture using a decontaminated stainless steel mixing spoon The sediment was then spooned into laboratory-supplied jars for analyses A chain-of-custody form was logged by the processing staff and relinquished to the laboratory staff (Appendix A) Fifty-seven samples were collected and submitted for analysis or sample archive A complete sample inventory including represented intervals and requested chemistry is shown in Table 3
Four stations required two co-located cores to achieve sufficient volume for bioassay archives Co-located cores differed by less than plusmn02 foot in mudline elevation with the exception of WWD02 which differed by 22 feet To adjust for the 22-foot difference in this sample the core closest to the target mudline elevation was deemed the primary core and intervals in the second core were adjusted to match the elevations of sampled strata from the primary core This decision was supported by lithography and physical sediment characteristics and was approved by USACE
24 Sediment Grab Collection
To collect a reference sample for comparison to samples submitted for biological testing a sediment grab sample was collected from a DMMP-approved reference area in Carr Inlet
Field Investigation Report August 2015 West Waterway Sediment Characterization 6 110003-0102
Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate
Field Investigation Report August 2015 West Waterway Sediment Characterization 8 110003-0102
Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

Sampling Methods
When processed the core caps were removed and the core was cut longitudinally using a circular saw Core segments were placed end-to-end from top to bottom to show the entire core length for photographing and sample-splitting The core was split with decontaminated stainless steel knives or spatulas into two halves for sampling The sulfides samples were collected from one-half of the core immediately after splitting placed in jars with 5 milliliters of 2-Normal zinc acetate per 30 grams and shaken vigorously to preserve the samples
Prior to further sampling field staff re-measured cores and delineated sampling intervals based on preliminary tide data from NOAA All cores were logged for major lithological features classified according to the Unified Soil Classification System and photographed (Appendix A) Sample intervals were based on recovered depth not corrected for length based on core recovery Elevations of core intervals (MLLW) and sample depths relative to mudline are shown in Table 2 Samples were placed in decontaminated stainless steel bowls and mixed until homogenous in color and texture using a decontaminated stainless steel mixing spoon The sediment was then spooned into laboratory-supplied jars for analyses A chain-of-custody form was logged by the processing staff and relinquished to the laboratory staff (Appendix A) Fifty-seven samples were collected and submitted for analysis or sample archive A complete sample inventory including represented intervals and requested chemistry is shown in Table 3
Four stations required two co-located cores to achieve sufficient volume for bioassay archives Co-located cores differed by less than plusmn02 foot in mudline elevation with the exception of WWD02 which differed by 22 feet To adjust for the 22-foot difference in this sample the core closest to the target mudline elevation was deemed the primary core and intervals in the second core were adjusted to match the elevations of sampled strata from the primary core This decision was supported by lithography and physical sediment characteristics and was approved by USACE
24 Sediment Grab Collection
To collect a reference sample for comparison to samples submitted for biological testing a sediment grab sample was collected from a DMMP-approved reference area in Carr Inlet
Field Investigation Report August 2015 West Waterway Sediment Characterization 6 110003-0102
Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate
Field Investigation Report August 2015 West Waterway Sediment Characterization 8 110003-0102
Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL
Field Investigation Report August 2015 West Waterway Sediment Characterization 13 110003-0102
5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

Sampling Methods
Washington Surface sediment was sampled from the 0- to 10-centimeter (cm) biologically active zone from a vessel using a decontaminated Van Veen grab sampler The sampler was deployed vertically through the water column until the bottom was reached The jaw assembly was closed to collect the sediment sample to a penetration depth of approximately 15 cm The apparatus was pulled upward out of the river bottom using a winch and raised to the surface
The sediment sample was retrieved aboard the vessel and met the following acceptability criteria
bull The grab sampler was not overfilled (ie the sediment surface was not against the top of sampler)
bull The sediment surface was relatively flat indicating minimal disturbance or
winnowing bull Overlying water was present indicating minimal leakage bull Overlying water had low turbidity indicating minimal sample disturbance bull The desired penetration depth (ie at least 10 cm) was achieved
Overlying water was siphoned off and a decontaminated stainless-steel spoon was used to collect the sediment from inside the sampler taking care not to collect sediment in contact with the sides or surface of the sampler

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate
Field Investigation Report August 2015 West Waterway Sediment Characterization 8 110003-0102
Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL
Field Investigation Report August 2015 West Waterway Sediment Characterization 13 110003-0102
5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

3 DATA QUALITY ASSESSMENT
This section provides information on data quality including field and laboratory QC measures Puget Sound Sediment Reference Material (PS SRM) results data validation findings and data completeness Chemistry laboratory reports are provided in Appendix B
31 Field Data Quality
Field data quality assurance (QA) measures outlined in the QAPP were followed with a few exceptions as described in the subsections below
311 Storage
All samples arrived at the laboratory within temperature requirements except for the bioassay samples sent from ARI to Northwestern Aquatic Sciences (NAS) and the reference sediment collected from Carr Inlet on March 19 2015 The bioassay samples sent from ARI were lost in shipment and arrived 3 days after delivery with temperatures when received at the laboratory ranging between 14 and 15 degrees Celsius (degC) These samples were still intact under nitrogen headspace and were immediately returned to refrigeration upon receipt at the laboratory DMMP was consulted prior to test initiation to verify that testing was still appropriate The reference sediment sample arrived to the chemistry laboratory at 121degC but was hand-delivered within 3 hours of collection so no data are expected to be affected The reference sediment sample arrived to NAS within temperature requirements
312 Field Quality Control Samples
Field QA samples proposed in the QAPP included temperature blanks and a rinse blank Temperature blanks were included in each cooler as required by the QAPP The rinse blank was unintentionally not collected however chemical concentrations are consistent across sampling days and are within expected concentrations for WW sediment so no data are expected to be affected by field contamination Three homogenate splits were also submitted with sediment samples to confirm adequate homogenization of samples and precision of analysis Results of the homogenate splits are included in the data validation reports in Appendix C and indicate that homogenization and analytical precision are adequate

Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

Data Quality Assessment
32 Puget Sound Sediment Reference Material
PS SRM was analyzed by ARI for dioxinfurans and polychlorinated biphenyls (PCBs) PS SRM is used to evaluate measurement accuracy and laboratory performance for dioxinfurans and PCB analyses of sediment collected in Puget Sound Laboratory results for these analyses were within the DMMP acceptance limits with the exception of 123478shyHxCDF and 123789-HxCDF which recovered slightly high in the PS SRM analyzed on February 18 2015 (SRM-021815) Aroclor 1254 was detected in the laboratory results but was not listed as a compound in the PS SRM certificate Aroclor 1260 was within acceptable limits
33 Analytical Data Quality
Data quality objectives (DQOs) and QA procedures are provided in the QAPP (Anchor QEA 2015) Data packages were validated by Laboratory Data Consultants in Carlsbad California US Environmental Protection Agency (EPA) Stage 4 data quality validation was performed for dioxinfurans All other data were validated at EPA Stage 2B Data validation reports are provided in Appendix C
All data qualifiers applied to the data during final validation have been incorporated into the database for this project Most data were considered useable as reported or as qualified Data qualifiers assigned during data validation include the following
bull ldquoJrdquo indicates that the associated numerical value is an estimated concentration bull ldquoUrdquo indicates a reporting limit below which the analyte was not detected bull ldquoUJrdquo indicates an approximate reporting limit below which the analyte was not
detected bull ldquoRrdquo indicates that the data are rejected and not usable for any purpose
The validation process resulted in the rejection of nine results due to low matrix spikematrix spike duplicate percent recoveries Eight semivolatile organic compound (SVOC) results (benzyl alcohol or 24-dimethylphenol) were rejected and one pesticide result (44rsquo-DDT) was rejected Certain other data were qualified as estimated values for a particular analysis based on a specified protocol or technical advisory as stated in the data validation reports
Field Investigation Report August 2015 West Waterway Sediment Characterization 9 110003-0102
Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

Data Quality Assessment
(Appendix C) Due to method blank contamination some results were qualified as non-detect at raised reporting limits
Overall reporting limits were deemed acceptable to meet project objectives Reporting limits for undetected results usually met or were below the DMMP SL Exceptions were noted in pesticide results due to matrix interference causing elevated reporting limits
34 Data Completeness
Data completeness for WW sediment characterization includes collection of required samples in the field and laboratory analysis for target chemicals as outlined in the project QAPP (Anchor QEA 2015) All target samples were collected and submitted for the analyses specified in the QAPP with the exception of Subsurface Interval C (8 to 12 feet below mudline) and Subsurface Interval D (12 to 14 feet below mudline) at station WWD23 These samples were not collected because the sample location was moved outside of the dry dock footprint to a deeper location
Laboratory data completeness was measured by percentage of results reported by the analytical laboratory Data completeness levels were set at 95 for all parameters according to DQOs specified in the QAPP (Anchor QEA 2015) A total of nine sample results were rejected after data validation DQOs were still met with 99 completeness

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically

Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

4 ANALYTICAL CHEMISTRY RESULTS
This section summarizes analytical results for conventional analyses DMMP standard chemicals of concern (COCs) and dioxinfurans including any exceedances of DMMP screening criteria
41 Conventional Analyses
Fifty samples were analyzed for conventional sediment parameters including total organic carbon total solids total volatile solids ammonia sulfides and grain size (Table 3) The results of these analyses are shown in Table 4
Total organic carbon ranged from 0149 to 372 with concentrations generally decreasing with core depth Total solids were consistent with sandy sediment ranging from 58 to 95 Total volatile solids ranged from 095 to 857 and were consistent with minimal presence of wood waste Ammonia concentrations ranged from 041 to 70 milligrams per kilogram (mgkg) and sulfide concentrations ranged from 13 to 2050 mgkg
Grain size analysis indicated that most samples from corresponding depth intervals had similar lithology with some exceptions Overall sediment samples were primarily composed of fine- and medium-grained sand and were low in clay (12 to 189) and gravel (01 to 62)
bull Of the 23 Surface A Interval samples all but five samples were predominately sand Samples from stations WWD01 WWD02 WWD08 and WWD10 had slightly greater fines content ranging from 504 to 596 fines Sample WWD05 was comprised equally of sand and fines and had higher gravel content (25) than other samples in this interval
bull Of the 20 Subsurface B Interval samples all but six were predominately sand Samples from stations WWD01 WWD02 WWD08 WWD13 WWD18 and
WWD21 had greater fines content ranging from 529 to 745 fines bull Of the seven Subsurface C Interval samples only station WWD01 was composed
predominately of fines (681)

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

Analytical Chemistry Results
42 DMMP Standard Chemicals of Concern
Fifty samples were analyzed for DMMP standard COCs including metals pesticides SVOCs polycyclic aromatic hydrocarbon (PAH) tributyltin (TBT) and PCBs (Table 3) All concentrations were screened against DMMP 2014 marine SLs maximum levels and bioaccumulation triggers (BTs) Complete results of these analyses are shown in Table 4 Eighteen samples (16 surface and 2 subsurface) had a detection that exceeded at least one DMMP marine evaluation criterion as shown in Tables 4 and 5 Figure 3 shows sample locations with a detected exceedance by depth interval
421 Surface A Interval Sediment Exceedances
In the Surface A Interval exceedance of SLs andor BTs occurred in 16 of 23 total samples with the northern portion of the navigation channel generally containing lower concentrations than the southern portion The following COCs were in exceedance of SLs andor BTs (Table 5)
bull Metals arsenic mercury and zinc bull SVOCs 14-dichlorobenzene benzoic acid and butyl benzyl phthalate bull Total PCB Aroclors bull TBT
Mercury was above the SL in 11 surface samples Arsenic and zinc exceeded SLs in one sample SVOC SL exceedances occurred in three samples Total PCB Aroclors exceeded the SL in 13 samples of which three also exceeded the BT TBT exceeded the BT in eight samples No PAH concentrations exceeded SLs Eight samples had one or more pesticide compounds with elevated reporting limits (above SLs) due to matrix interference These compounds include 44-DDT dieldrin heptachlor sum of 44 DDT DDE and DDD and total chlordane The laboratory indicated that there were no further cleanups available to remove the matrix interferences
422 Subsurface B Interval Sediment Exceedances
In the Subsurface B Interval exceedance of SLs occurred in 2 of 20 samples Both exceedances were in the southern portion of the navigation channel (WWD01 and WWD02) The following COCs were in exceedance of SLs andor BTs (Table 5)
Field Investigation Report August 2015 West Waterway Sediment Characterization 12 110003-0102
At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically

Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

At station WWD01 mercury pyrene total PCB Aroclors and TBT were detected above SLs andor BTs At station WWD02 only total PCB Aroclors were detected above the DMMP SL One sample had pesticide compounds with elevated reporting limits due to matrix interference (44-DDT dieldrin heptachlor and total chlordane)
423 Subsurface C and D Interval Sediment Exceedances
There were no SL or BT exceedances in the seven Subsurface C Interval samples All samples from the Subsurface D Interval were archived and have not been submitted for chemical analysis
43 DioxinFurans
A subset of 25 samples was submitted for dioxinfuran analysis (Table 3) Of 13 samples in the Surface A Interval 8 exceeded the screening level of 4 parts per trillion toxicity equivalent (Table 5)
None of the 10 samples from Subsurface Interval B nor two samples in Subsurface Interval C exceeded the DMMP SL

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically
Field Investigation Report August 2015 West Waterway Sediment Characterization 14 110003-0102
Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

5 BIOLOGICAL TESTING RESULTS
Of the 11 samples for which sufficient sediment was collected for bioassays the four samples with SL exceedances were subjected to marine bioassay testing Samples were sent to NAS in Newport Oregon for the following tests
bull Eohaustorius estuarius 10-day amphipod mortality test bull Neanthes arenaceodentata 20-day juvenile infaunal growth test bull Mytilus galloprovincialis larval development test
Appendix D contains the NAS laboratory report and statistical analysis The subsections below provide a summary of results compared to non-dispersive criteria (based on Elliott Bay disposal site)
Prior to testing all samples were stored at ARI at 4degC and the headspace was purged with nitrogen Shipping container and delivery issues occurred as described in Section 311 All samples were intact and brought back to required temperatures upon arrival at the laboratory Initial tests were started within the 56-day holding time but due to suspected organism health issues and a reference sediment failure the larval development bioassay was re-tested with a new supply of organisms 75 days after sample collection The decision to retest samples was made in consultation with USACE
In consultation with USACE a reference sediment sample was collected from Carr Inlet north of Raft Island Washington (1183501 Easting 126952 Northing) A sediment field grain-size kit was used to compare percent total fines in the reference sample to samples submitted for analysis Sediment was submitted to ARI for laboratory grain size and conventional analyses Table 6 shows the grain size total solids TOC ammonia and sulfide concentrations of the bioassay samples including the reference sample The fines content of the test samples matched well with the reference sediment with the exception of WWD12shy0-4 which had a significantly lower fines content (152) than the reference (458)
51 Eohaustorius estuarius 10-Day Amphipod Mortality Test
Results of the 10-day amphipod mortality test are provided in Table 7 Two samples WWD02-0-4-150205 and WWD05-0-4-150206 exhibited a mortality that was statistically

Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria

Biological Testing Results
different than the reference sample and greater than 20 over the negative control (ie hits under the 2-hit rule)
52 Neanthes arenaceodentata 20-Day Juvenile Infaunal Growth Test
Results of the 20-day juvenile infaunal growth test are provided in Table 8 None of the growth rates in any sample failed the non-dispersive criteria
53 Mytilus galloprovincialis Larval Development Test
Results of the larval development test are provided in Table 9 The normal survival was used for data analysis and interpretation rather than the normalized combined mortality and abnormality because some test replicates had higher survival than the average control replicate value None of the samples was statistically significantly lower than the reference sample and therefore none failed the non-dispersive criteria
54 Summary of Biological Testing
A summary of biological testing results are presented in Table 10 Two samples exceeded the 2-hit rule for one bioassay test however because there were no failures in the other tests these samples passed the marine bioassay criteria All other samples passed all test criteria
