I .O Executive Summary

The property located at 169 Main Street in Windsor, Vermont been operated as a gasoline-dispensing facility since at least 1960. The current UST system on the site includes three 8,000-gallon gasoline double-walled fiberglass USTs which were installed in 2000. Other OHM stored at the facility includes a 275-gallon AST (presumed to be fuel oil) and a propane tank.

In May 2000, three 8,000-gallon gasoline underground storage tanks (USTs) were removed from the site and replaced with the three USTs mentioned above.. The tanks removed from the site were noted to be in good condition; however, approximately 570 tons of petroleum-impacted soil were removed from the site during the UST removal.

In June 2005, CFI conducted site work consisting of upgrading the gasoline dispensers. During the excavation for the new canopy footing, elevated PID readings were encountered from soil in the vicinity of canopy footings. ECS submitted the results of the PID screening and in June 2005, the VTDEC required that CFI conduct a Site lnvestigation to determine the extent of contamination at the site detected during the June 2005 site work. On September 15, 2005, ENSR submitted a Preliminary Work Plan to conduct the Site lnvestigation and on September 27, 2005, the VTDEC approved of the Preliminary Work Plan.

On November 23, 2005, ENSR completed a total of four borings and the installation of three monitoring wells within the borings as part of this investigation. Groundwater flow direction beneath the property was determined to be to the southwest. Five temporary soil gas points were also installed across the site. Based on the results of the soil gas survey, there appears to be no vapor migration from the contamination plume to the on-site building or any of off-site properties.

Soil sampling and analysis indicates the presence of petroleum compounds above laboratory detection limits but below the USEPA PRGs. Groundwater was also found to be affected by gasoline-related compounds at concentrations greater than applicable VGES adjacent to the gasoline dispensers and in one monitoring well downgradient from the gasoline dispensers.

Based on the assessment performed, ENSR recommends collecting quarterly groundwater samples and groundwater elevations for four quarterly sampling events to evaluate seasonal groundwater conditions. An Annual Summary Report should be submitted updating the conceptual model and evaluating if additional activities are needed at this site.

2.0 Introduction

The purpose of this report is, to present the results of a Site lnvestigation conducted by ENSR, on behalf of Cumberland Farms, Inc. (CFI). This Site lnvestigation was completed to assess the potential release of petroleum products at the CFI facility, located at 169 Main Street in Windsor, Vermont. All opinions presented in this report are based solely upon this investigation and are subject to the Service Constraints included in Appendix A.

In June 2005, Environmental Compliance Services, Inc. (ECS) submitted a letter summarizing field activities conducted during an underground storage tank (UST) piping upgrade at the site. During the UST piping upgrade, elevated photo-ionization detector (PID) readings were noted in the soil under one of the canopy footings. As a result of the elevated PID readings, the Vermont Department of Environmental Conservation (VTDEC) requested that an additional investigation be performed in order to determine the extent of contamination.

The following activities were completed between October and December 2005, as part of the Site Investigation: city and municipal file review; preliminary sensitive receptor evaluation; advanced four soil borings three of which were completed as monitoring wells; collected soil samples for laboratory analysis, collected one round of groundwater samples for laboratory analysis; performed a soil gas survey; and completed a well head survey of the monitoring wells. The scope of work was summarized in the September 2005 Preliminary Work Plan that was approved by the VTDEC on September 27, 2005.

Please refer to Figure 1, Site Locus, for the regional location of the site, and Figure 2, the Site Plan, for pertinent site features.

This Site lnvestigation Report was prepared in accordance with the approved work plan. The VTDEC Sites Management Section (SMS), June 2005 Site lnvestigation Procedure guidance document was used as .

guidance in the completion of this investigation.

4.0 Site History

4.1 Current and Historical Uses of the Facility The subject site has reportedly been utilized as a gasoline station and convenience store since its original construction in 1960. Prior to 1960, the land was reportedly undeveloped. Petco Mini Mart gasoline service station, convenience store and car wash were present on the property between 1960 and 1981. The records reviewed for this report did not indicate what the site was used as since 1981. However, based on previous reports, it appears to have been used as a gasoline station. There was no additional information concerning the site available at the town offices.

The facility is currently occupied by a CFI convenience store and gasoline station. The current building at the site was constructed on a concrete slab foundation in 2005. Refer to Appendix B for photographs of the site.

4.2 Release History In May 2000, Lincoln Applied Geology, Inc. (LAG) submitted an Underground Storage Tank Removal and Site Assessment Report, documenting the removal and closure of three 8,000-gallon fiberglass USTs originally installed in 1983. Approximately 570 tons of petroleum-impacted soils were removed from the site during the UST excavation. The VrDEC issued site number 2000-2767 to the property, due to the contamination detected during the construction activities.

In May 2005, ECS submitted a UST Closure Report documenting the permanent closure of a 1,000-gallon gasoline steel UST. No evidence of a release was detected and no soil was removed from the site during the UST removal. In June 2005, ECS submitted a letter documenting field activities conducted during a UST piping upgrade, which included excavations for new canopy footings. During the piping upgrade, ECS performed PID screenings of the soil for the presence of petroleum vapors. Based on the PID screening, vapors were detected at elevated levels around one of the canopy footings; however, soil samples were not collected for laboratory analysis from this location. Based on the work conducted for the UST piping upgrade, ECS concluded that no further assessment was warranted. However, on July 21,2005, the VTDEC SMS issued Site# 2005-3389 and requested that additional investigation be conducted to further assess the contamination detected during the piping upgrade.

According to a June 21, 2005 VTDEC correspondence, the site was previously listed on the Vermont Active Hazardous Site Lists as SMS Site #2000-2767 and was closed in February 2002. The SMS also stated that the contamination detected during the June 2005 excavation may be a result of a historic release at the site.

4.3 Oil and Hazardous Material Storage and Use History

4.3.1 UST System Currently, there are three 8,000-gallon double-walled fiberglass gasoline USTs at the site. 'The USTs were installed in 2000. Each of the tanks has overf~lllspill protection, interstitial leak detection, pipe protection and interstitial line leak detectors. No other information was available at the town offices concerning the history tanks at the property.

4.3.2 Other Oil and/or Hazardous Material

Additional oil and/or hazardous material (OHM) observed on-site consists of a 275-gallon AST and propane tank. According to Lona Roberts, the store manager, the building is heated by fuel oil; therefore, the AST is inferred to contain fuel oil. No staining or leakage was observed to be associated with the AST.

4.4 Previous Environmental Investigations Underground Storage Tank Removal and Site Assessment, CFI Facility #4005, Windsor, Vermont (UST Facility 10#6749956), by Lincoln Applied Geology, Inc. of Lincoln, VT, May 2000.

In May 2000, LAG submitted a UST Removal and Site Assessment Report documenting the closure and removal of three 8,000-gallon fiberglass USTs, originally installed in 1983. Approximately 570 tons of petroleum-impacted soil were removed from the site during the UST excavation. Soil samples were collected from the bottom of the excavation, sidewalls and beneath the gasoline dispensers. The analytical results did not show gasoline-related volatile organic compound (VOCs) or total petroleum hydrocarbons (TPH) concentrations in the soil samples above laboratory detection limits. LAG conducted a survey of the site and surrounding properties to determine if any potential receptors were at risk of being impacted by the contamination at the site. LAG determined that the only potential receptor of the contamination was the soil beneath the site.

UST Closure Report, CFI Store #4005, Main Street, Windsor, Vermont, by Environmental Compliance Services, Inc. of Brattleboro, VT, May 2005.

In May 2005, ECS submitted a UST Closure Report documenting the permanent closure of a 1,000-gallon steel gasoline UST. Based on the absence of elevated PID readings from soil samples taken during the removal of the tank, confirmatory samples were not collected. Soils in the immediate vicinity of the former UST consisted of dry brown coarse to medium-grained sands. Based on their investigation, ECS concluded that no further assessment was warranted for the site.

UST Piping Closure Report, CFI Store #4005, Main Street, Windsor, Vermont, by Environmental Compliance Services, Inc. of Brattleboro, W, June 2005.

In June 2005, ECS submitted a letter documenting field activities conducted during a UST piping upgrade, which included excavations for new canopy footings. During the excavation of one of the footings, elevated PID readings were detected from soil around one of the former footings. Soil samples were not collected and ECS determined that no further actions were required.

5.0 Field Investigations and Hydrogeolical Characteristics

5.1 Work Plan and Deviations On September 15, 2005, ENSR submitted a work plan that proposed soil borings, well installation, groundwater gauging, groundwater sampling and a soil gas survey to investigate the petroleum contamination detected by ECS in June 2005. The location of the wells was selected to evaluate potential groundwater contamination near one of the canopy footings. The soil gas points were selected to determine the potential for petroleum vapor migration to the surrounding properties.

On September 27, 2005, the VrDEC approved the work plan to address petroleum contamination at the site There were no deviations from the September Work Plan during the site investigation.

5.2 Drilling and Monitoring Well Installation Drilling Date(s): November 23,2005

Drilling Contractor: Geosearch, Inc., of Fitchburg, Massachusetts

Boring Numbers: MW-1, MW-2, MW-3 and SB-3

Monitoring Wells Installed: MW-1, MW-2 and MW-3 Temporary Well SB-3

Drilling Method: Geoprobe direct push technology

Sampling Method: Continuous acetate sleeves

Depth to Groundwater: Approximately 18 feet below grade at the time of drilling

Screening Method: Headspace with PID/olfactory/visual

Laboratory Sample1 SelectionIDepth: Based on highest PID reading or just above the water table

Separate-P hase Hydrocarbons (SPH): None observed

The temporary well (SB-3) was installed within the gasoline dispenser pad to assess contamination detected during the piping upgrade in the summer of 2005. The three permanent wells were installed to delineate the extent of any contamination that may be present in the subsurface. Please refer to Appendix C, Boring Logs, for further information on boring completion and well construction, and Figure 2, Site Plan, for boring and monitoring well locations.

5.3 Wellhead Survey Survey Date: Decem ber 7,2005

Benchmark: 100.00 feet (arbitrary), located on corner of gasoline dispenser

Survey Type: Elevation

Survey Items: Monitoring wells MW-1 through MW-3

Please refer to Table 1, Groundwater Elevation Data, for well-head elevations, depth to water and groundwater elevations. Groundwater elevations, groundwater topography and groundwater flow direction are presented on Figure 2.

5.4 Soil and Groundwater Sampling Sampling Date(s): Soil and Groundwater - November 23,2005

Groundwater - December 7,2005

Soil Sample Collection Points: MW-2: 15 - 17 feet below surface grade (bsg); SB-3: 7-9 feet bsg;

Groundwater Sample Collection Points: November 23, 2005: SB-3

December 7,2005 Monitoring wells MW-1 through MW-3

On November 23, 2005, two soil samples (SB-3 and MW-2) were collected for laboratory analysis. During the screening of the soil for all soil borings, PID readings were only encountered from SB-3 and MW-2. Therefore, soil samples were collected only from these two borings. The sample depths for both borings were based on the highest PID readings.

Based on field notes taken by the previous consultant ENSR installed Well MW-2 to investigate conditions observed by the previous consultant. Based on field observations on the day of drilling, ENSR anticipated that groundwater was moving from the gasoline dispensers towards well MW-2. Since elevated PID readings were encountered from soil in this well, a sample was collected to assess conditions that were believed to be downgradient of the gasoline dispensers. (Based on the hydrogeologic information collected after the soil boring activities (presented in section 5.6.2) well MW-2 is cross-gradient to the gasoline dispensers.

Based on the field notes taken by the previous consultant, elevated PID readings were encountered around the current canopy footing. The VTDEC, requested that this area be investigated as part of this investigation The placement of the boring was restricted based on the location of product lines. Based on the highest PID readings, one soil sample was collected from this point to assess conditions observed during the June 2005 upgrade.

ENSR did not install a permanent well in this location due to the proximity of the well in relation to the gasoline dispenser. A permanent well in this location could act as a preferential pathway into the surficial aquifer from small releases. Based on VTDEC guidance, since a well was not being installed, a soil sample was collected from this point.

One groundwater sample, SB3GW, was collected from a temporary well installed in boring SB-3 and removed on the same day. Soil and groundwater samples were analyzed for VOCs and TPH. Refer to Table 2, Soil Analytical Data and Table 3 Groundwater Volatile Organic Compound Analytical Results for summaries of the laboratory analytical results.

April 2006

ENSR I ?EC'.2'\; 8

On December 7, 2005, groundwater samples were collected from wells MW-1, MW-2 and MW-3 and analyzed for VOCs and TPH. Prior to sampling, approximately 3 to 5 well volumes of water were purged from the wells and samples were collected with a dedicated disposable bailer. Refer to Table 3, Groundwater VOC Analytical Results, and Table 4, Groundwater TPH Analytical Results, for a summary of the laboratory analytical results.

All samples were collected following the Site Investigation Work Plan. The results of the soil and groundwater sampling are summarized in Section 5. The laboratory analytical results from the soil and groundwater sampling are included in Appendix D.

5.5 Soil Gas Survey Survey Date: November 23, 2005

Survey Sample Collection Points: SG-1 through SG-5, screened approximately 3-5 feet BSG

PID Model: Thermo Environmental OVM 5808 with a 10.6 eV lamp

On November 23, 2005, ENSR advanced five temporary soil vapor screening points (SG-1 through SG-5) using the Geoprobe unit. The soil gas points were removed at the conclusion of the soil gas tests. All points were installed to five feet below grade with the bottom two feet screened. A bentonite seal was placed around the annulus space to prevent vapor migration. The PID was calibrated in the field using 100 parts-per-million isobutylene gas. Soil gas was purged from the subsurface using a low-flow battery powered pump and screened with a PID. No PID readings were detected above the instrument detection limits. All soil vapor screening results are summarized in Table 5 and the locations of the soil vapor points are provided in Figure 2.

5.6 Subsurface Conditions

6.0 Nature and Extent of Contamination

6.1 Analytical Results As part of this Site Investigation, ENSR collected soil and groundwater samples from the assessment performed. All soil and groundwater samples collected for laboratory analysis were stored on ice in the field and delivered under chain-of-custody to Groundwater Analytical, Inc, (Groundwater) of Buzzards Bay, Massachusetts. Analyses were selected based on current facility use and PID screenings.

Soil Analyses:

November 23, 2005 All soil samples were analyzed for the presence of VOCs by EPA Method 8260 and TPH by Modified 801 5. Refer to the Boring Logs in Appendix C for PID readings. Refer to Table 2 for a summary of the soil analytical results.

Groundwater Analyses:

December 7, 2005 All groundwater samples were analyzed for the presence of VOCs by Method 8260 and TPH by Modified Method 801 5. Refer to Tables 3 and 4 for a summary of the groundwater analytical results. Laboratory analytical results and chain of custody documentation are included in Appendix D.

6.2 Extent of Contamination (Soil and Groundwater) Soil -

The locations of the soil borings and wells were determined based on the PID screenings recorded during the piping upgrade completed by ECS in June 2005. Based on the field measurements from ECS, it appeared that contaminated soil was present underneath one of the current gasoline dispensers.

During this investigation, one soil sample (SB-3) and a grab groundwater sample (SB-3GW) were collected adjacent to the dispenser pad to further evaluate conditions detected in June 2005. A permanent monitoring well was not installed at this location. Based on historic information, two monitoring wells (MW-1 and MW-2) were installed between the current UST system and the gasoline dispenser pad. A third well (MW-3) was installed north of the gasoline dispensers to help determine groundwater flow direction and plume delineation.

Based on the laboratory analysis of the soil samples, it appears that petroleum-impacted soil is present underneath the gasoline dispensers and between the USTs and dispenser pad. The VOC concentrations were detected above laboratory detection limits; however, the concentrations were below U.S. EPA Preliminary Remedial Goals (PRGs) for direct contact exposure pathway for industrial use. TPH was also detected above laboratory detection limits, ranging in concentrations from 400 milligram-per-kilogram (mglkg) in SB-3 to 730 mglkg at MW-2. Neither the U.S. EPA nor the VTDEC currently have a standard for TPH in soil. No soil samples were collected from MW-1 and MW-3, due to low PID readings in the soil. Results of soil laboratory analyses are presented in Table 2 and copies of the laboratory reports are included in Appendix D.

Groundwater

Based on the groundwater analytical results, petroleum constituents were detected in the samples collected from SB-3 and well MW-1. Naphthalene, 1,2,4-trimethylbenzene and 1,3,5-trimetylbenzene were present in sample SB-3GW above the Vermont Groundwater Enforcement Standards (VGES) and 1,2,4-

J:\Northboro\PSnCFI 2140\Vermonl 214O\Windsor - 314\Reporls\Sile Invesllgalion\SI Report Drafl.doc

April 2006

trimethylbenzene and 1,3,5-trimetylbenzene were detected in well MW-1 above the VGES. TPH was detected above laboratory detection limits, ranging in concentrations from 0.7 milligram-per-liter (mg1L) in MW-1 to 2.7 mg/L at SB-3GW. There are currently no VGES or RBC standards for TPH in groundwater. Results of groundwater laboratory analyses are presented in Tables 3 and 4 and copies of laboratory reports are included in Appendix D.

Based on the analytical results, there appear to be low levels of petroleum constituents in the subsurface. The highest VOC concentrations were detected in SB-3 underneath the dispensers. Lower levels of contaminants were detected in well MW-1 which is located downgradient of SB-3. Only 1,3,5- and 1,2,4-trimethyl benzene are above standard in well MW-1. Based on the contamination distribution and ENSR's experience with contamination at other retail petroleum sites, ENSR does not recommend installation additional wells at this time.

7.0 Risk Evaluation

7.1 Source Protection Areas Based on field observations and the Site Locus the following source protection areas were observed within 500 feet of the site:

Water Wells: Based on information obtained from the Windsor Town Hall, there are no registered residential water wells located in the area.

Surface Water Bodies: None observed;

Buildings with basements: Based on field observations some of the surrounding residential properties have

basements;

Wetlands: None observed;

Sensitive Ecological Areas: None observed;

Utilities Corridors: Because the depth of groundwater is below the suspected depth of any underground utilities at this site, ENSR believes that the migration potential of dissolved-phase contaminants into these utilities is low.

Direct Soil Contact Areas: None: All impacted soil is below 3 feet or beneath pavement

7.2 Fate, Transport and Contaminates of Concern Various gasoline-related constituents have been detected in the soil and in the groundwater at the disposal site. Information is presented in Appendix E which provides a general characterization of the environmental fate and transport properties associated with the constituents detected in one or more of these media at the disposal site. Based on these constituent-specific fate and transport characteristics and disposal site conditions, general information about disposal site specific fate and transport characteristics was developed. Therefore, the information presented in Appendix E is intended only to provide information on potential fate and transport mechanisms for various compounds detected at the site.

8.0 Conceptual Model

As required in the Site Investigation Procedure guidance document, the following is a Preliminary Conceptual Model based on the information collected to date:

Soil and groundwater in the immediate vicinity of the current gasoline UST system is impacted with low levels of petroleum constituents. The source of the petroleum constituents appears to be a release from the former UST system andlor the historical use of the site for dispensing gasoline. A release from the former UST system would have initially impacted soil and ultimately migrated downward to the groundwater table to a depth of 16-19 feet bsg. Direct exposure to the impacts identified in soil and groundwater is unlikely based on the depth of the impacts and the fact that the impacted area is paved or beneath concrete.

The primary migratory pathway for gasoline released to the subsurface was determined to be migration with groundwater flow in a southwesterly direction, using the groundwater gauging data from December 2005. Because the depth of groundwater is below the suspected depth of any underground utilities at this site, ENSR believes that the migration potential of dissolved-phase contaminants into these utilities is low.

With the exception of several residential structures with basements, there were no Source Protection Areas (drinking water sources, surface water bodies, wetlands, etc.) identified within 500 feet of the site. Volatilization of gasoline compounds in the unsaturated zone andlor adsorption onto soil particles, prior to the release reaching the water table as well as volatilization from the groundwater to the unsaturated zone, is dependent on the individual characteristics of each petroleum compound. Based on the results of a limited soil gas survey, groundwater contamination distribution and the depth to groundwater, there does not appear to be a significant risk of petroleum vapor migration to the surrounding properties or surrounding utilities.

9.0 Summary and Recommendations

Based on the Site lnvestigation performed by ENSR and subject to the Service Constraints in Appendix A, ENSR presents the following summary and opinions regarding CFI Facility #4005 located at 169 Main Street in Windsor, Vermont.

1. The facility has been operated as a gasoline-dispensing facility since at least 1960. The current UST system on the site includes three 8,000-gallon gasoline double-walled fiberglass USTs which were installed in 2000. Other OHM stored at the facility includes a 275-gallon AST (presumed to be fuel oil) and a propane tank. No staining or leakage was observed to be associated with the AST.

2. According to a Tank Pull Form reviewed in the UST Tank Removal Report, dated May 2000, three 8,000- gallon gasoline USTs were removed from the site and replaced with the three current USTs. The tanks removed from the site were noted to be in good condition; however, approximately 570 tons of petroleurn- impacted soil were removed from the site during the UST removal.

3. In June 2005, CFI conducted site work consisting of upgrading the gasoline dispensers. During the excavation for the new canopy footing, elevated PID readings were encountered from soil in the vicinity of canopy footings. ECS submitted the results of the PID screening and in June 2005, the VTDEC required that CFI conduct a Site lnvestigation to determine the extent of contamination at the site detected during the June 2005 site work. On September 15, 2005, ENSR submitted a Preliminary Work Plan to conduct the Site lnvestigation and on September 27, 2005, the VTDEC approved of the Preliminary Work Plan.

4. On November 23, 2005, ENSR completed a total of four borings and the installation of three monitoring wells within the borings as part of this investigation. Groundwater beneath the property was encountered at a depth of approximately 16 to 19 feet below grade. Groundwater flow direction beneath the property was determined to be to the southwest.

5. Soil sampling and analysis indicates the presence of petroleum compounds above laboratory detection limits but below the USEPA PRGs. Groundwater was also found to be affected by gasoline-related compounds at concentrations greater than applicable VGES adjacent to the gasoline dispensers and in one monitoring well downgradient from the gasoline dispensers.

6. On November 23, 2005, a soil gas survey was conducted on five temporary soil gas points installed across the site. Based on the limited soil gas survey, indoor air exposure is unlikely.

7. Potential sources of contamination include the current and former gasoline UST system(s) and historical facility use. It is ENSR's opinion that the potential for preferential migration of impacted groundwater along subsurface utilities and the potential for soil and groundwater to be a source of vapors to occupied structures is unlikely.

8. No known exposures have occurred from contaminants detected at the site. In ENSR's opinion, exposure potential is most likely limited to construction workers who may complete excavations on-site. On-site workers are not expected to be affected because the impacted area is paved, no vapors have been detected and there have been no complaints of vapors in the area.

9. ENSR recommends collecting quarterly groundwater samples and groundwater elevations for four quarterly sampling events to evaluate seasonal groundwater conditions. An Annual Summary Report should be submitted updating the conceptual model and evaluating if additional activities are needed at this site.

Quality AssurancelQuality Control

- .- - - - -- - .- A - - - - - - - A. Program Overview

- - - - - - . - - -- - - - . Groundwater Analytical conducts an active Quality Assurance program to ensure the production of high quality, valid data. This program closely follows the guidance provided by Interim Guidelines and Specifications for Preparing Quality Assurance Project Plans, US EPA QAMS-005180 (1980), and Test Methods for Evaluating Solid Waste, US EPA, SW-846, Update 111 (1996).

Quality Control protocols include written Standard Operating Procedures (SOPS) developed for each analytical method. SOPS are derived from US EPA methodologies and other established references. Standards are prepared from commercially obtained reference materials of certified purity, and documented for traceability.

Quality Assessment protocols for most organic analyses include a minimum of one laboratory control sample, one method blank, one matrix spike sample, and one sample duplicate for each sample preparation batch. All samples, standards, blanks, laboratory control samples, matrix spikes and sample duplicates are spiked with internal standards and surrogate compounds. All instrument sequences begin with an initial calibration verification standard and a blank; and excepting GCJMS sequences, all sequences close with a continuing calibration standard. GUMS systems are tuned to appropriate ion abundance criteria daily, or for each 12 hour operating period, whichever i s more frequent.

Quality Assessment protocols for most inorganic analyses include a minimum of one laboratory control sample, one method blank, one matrix spike sample, and one sample duplicate for each sample prepar2tlon batch. Standard curves are derived from one reagent blank and four concentration levels. Curve val~drty 1 5

verified by standard recoveries within plus or minus ten percent of the curve.

B. Definitions = --

Batches are used as the basic unit for Quality Assessment. A Batch i s defined as twenty or fewer samples of the same matrix which are prepared together for the same analysis, using the same lots of reagents and the same techniques or manipulations, all within the same continuum of time, up to but not exceeding 24 hours.

Laboratory Control Samples are used to assess the accuracy of the analytical method. A Laboratory Control Sample consists of reagent water or sodium sulfate spiked with a group of target analytes representative o i tho method analy-tes. Accuracy is defined as the degree of agreement of the measured value wrth the trur or expected value. Percent Recoveries for the Laboratory Control Samples are calculated to assess accuracy

Method Blanks are used to assess the level of contamination present in the analytical system. Method Blanks consist of reagent water or an aliquot of sodium sulfate. Method Blanks are taken through all the appropriate steps of an analytical method. Sample data reported is not corrected for blank contaminat~on.

Surrogate Compounds are used to assess the effectiveness of an analytical method In dealrng w ~ r h each sample matrix. Surrogate Compounds are organic compounds which are similar to the target analvtes o i interest in chemical behavior, but which are not normally found in environmental samples. Perccnr Recoveries are calculated for each Surrogate Compound.

Quality AssurancelQuality Control

Groundwater Analytical conducts an active Quality Assurance program to ensure the production of high quality, valid data. This program closely follows the guidance provided by Interim Guidelines and Specifications for Preparing Quality Assurance Project Plans, US EPA QAMS-005180 (1980), and Test Methods for Evaluating Solid Waste, US EPA, SW-846, Update 1 1 1 (1 996).

Quality Control protocols include written Standard Operating Procedures (SOPS) developed for each analytical method. SOPS are derived from US EPA methodologies and other established references. Standards are prepared from commercially obtained reference materials of certified purity, and documented for traceability.

Quality Assessment protocols for most organic analyses include a minimum of one laboratory control sample, one method blank, one matrix spike sample, and one sample duplicate for each sample preparation batch. All samples, standards, blanks, laboratory control samples, matrix spikes and sample duplicates are spiked with internal standards and surrogate compounds. All instrument sequences begin with an initial calibration verification standard and a blank; and excepting GUMS sequences, all sequences close with a continuing calibration standard. GUMS systems are tuned to appropriate ion abundance criteria daily, or for each 12 hour operating period, whichever is more frequent.

Quality Assessment protocols for most inorganic analyses include a minimum of one laboratory control sample, one method blank, one matrix spike sample, and one sample duplicate for each sample preparation batch. Standard curves are derived from one reagent blank and four concentration levels. Curve validity is verified by standard recoveries within plus or minus ten percent of the curve.

Batches are used as the basic unit for Quality Assessment. A Batch is defined as twenty or fewer samples of the same matrix which are prepared together for the same analysis, using the same lots of reagents and the same techniques or manipulations, all within the same continuum of time, up to but not exceeding 24 hours.

Laboratory Control Samples are used to assess the accuracy of the analytical method. A Laboratory Control Sample consists of reagent water or sodium sulfate spiked with a group of target analytes representative of the method analytes. Accuracy is defined as the degree of agreement of the measured value with the true or expected value. Percent Recoveries for the Laboratory Control Samples are calculated to assess accuracy.

Method Blanks are used to assess the level of contamination present in the analytical system. Method Blanks consist of reagent water or an aliquot of sodium sulfate. Method Blanks are taken through all the appropriate steps of an analytical method. Sample data reported is not corrected for blank contamination.

Surrogate Compounds are used to assess the effectiveness of an analytical methoi in dealing with each sample matrix. Surrogate Compounds are organic compounds which are similar to the target analytes of interest in chemical behavior, but which are not normally found in environmental samples. Percent Recoveries are calculated for each Surrogate Compound.

Contaminants of Concern

Report Drafl-end Sheels.doc

Gasoline is a complex mixture of several hundred different hydrocarbons derived from refined petroleum. The primary classes of hydrocarbon compounds contained in gasoline are aliphatic (straight-chain, branched, and cyclo-alkanes or paraffin's), aromatics, and alkenes (olefins) with a distribution generally consisting of 49%-62% aliphatic hydrocarbons, 20%-49% aromatics and 1 %-I1 % alkenes. The aliphatic compounds with concentrations in gasoline greater than 1% are the compounds with 4 to 12 carbons (C4-C12) (ABB, 1990). Non-hydrocarbon components of gasoline include sulfur, nitrogen, oxygen, and trace metals.

Because gasoline consists of a very large number of individual compounds, several indicator compounds and compound groups have been used to characterize the physical and chemical properties of the gasoline contaminant in this assessment. The indicator compounds used are benzene, toluene, ethylbenzene, ortho-, meta-, and para-xylenes (BTEX), methyl tertiary-butyl ether (MTBE) and total petroleum hydrocarbons (TPH). These compounds were chosen because of their potential toxicity to human health, and their environmental significance. They are U.S. Environmental Protection Agency (EPA) priority pollutant compounds whose concentrations in drinking water are restricted.

The characteristics considered in evaluation of the fate and transport potential of these compounds and compound groups in the environment are solubility, vapor pressure, Henry's Law Constant, fuel-water partition coefficient, adsorption coefficient, and degradation half life.

A. Solubility

Solubility (S) is the extent to which a solute substance mixes with water. It is an important parameter in the transport, persistence, and fate of gasoline-derived hydrocarbons in natural systems. The solubility of a compound and its subsequent concentration in water affect the compound's sorption, dispersion, diffusion, volatilization, degradation, toxicity, and bioaccumulation. Laboratory data regarding solubility in water is available for many of the individual gasoline constituents, although the aquifer temperature, pH, ionic strength, and soil characteristics all may affect hydrocarbon dissolution in the vadose and saturated zones.

Benzene, butadiene, and other aromatic compounds including toluene, ethylbenzene, and xylenes are the most soluble gasoline compounds. Generally, ring formation increases the solubility of a hydrocarbon in water for a given carbon number. A decrease in saturation within a ring structure results in a decrease in solubility. The solubility in water of the gasoline additive MTBE is approximately 4.3% (Garrett et al., 1 986).

The presence of several hydrocarbons in a natural system could produce solubilities different than those predicted for the individual components, due to differences in partitioning and to chromatographic effects (American Petroleum Institute, 1985a). These concentrations are significantly less than the solubility of the individual components. However, the presence of MTBE has been reported to increase the solubility of the BTEX compounds (Garrett et al., 1986).

B. Vapor Pressure

Vapor pressure (V) is a description of volatilization, and indicates the extent to which a chemical will be present in the vapor phase in the environment. A chemical with a low vapor pressure is less likely to volatilize than one with a high vapor pressure.

The aliphatic gasoline constituents have the highest vapor pressures, followed by the olefins. The volatility of gasoline is due mainly to butane and pentane (ABB, 1991). For these constituents, vapor pressure decreases with increasing molecular weight. Vapor pressure also decreases with increasing degree of substitution. The vapor pressure of benzene (the most volatile aromatic compound) is slightly less than that of n-hexane tC6).

C. Henry's Law Constant

The Henry's Law Constant (H) is used to estimate the concentration of a solute near the vapor-liquid interface of a dilute solution. The constant is the ratio, under equilibrium conditions, of the vapor pressure of a constituent to its concentration in the aqueous phase. Henry's Law Constants can be measured directly or can be calculated from vapor pressure and water solubility data. The larger the Henry's Law Constant, the more likely a constituent is to volatilize from the liquid phase. The gasoline constituents with the highest Henry's Law Constants are the higher molecular weight alkanes (due to their relatively high vapor pressures and low solubility).

D. Adsorption Coefficient

The adsorption coefficient (Kd) expresses the extent to which an organic chemical partitions between a solid phase and a liquid phase. The larger the Kd, the greater the extent of partitioning to the solid phase. Adsorption coefficients can be measured for a particular solid in the laboratory or the coefficients may be estimated using other physicallchemical constants. One way to express the adsorption coefficient is based on adsorption to organic carbon in the solid-phase medium. This form of the adsorption coefficient is designated as Koc. The Koc can be calculated using solubility (S) by the following equation (Bruce et al., 1991):

The amount of adsorption can then be estimated using the fraction of organic material in the solid phase. Since the Koc is inversely proportional to solubility, the gasoline constituents which are least soluble are most likely to be adsorbed onto the solid phase. Thus, MTBE would not be expected to be greatly sorbed to soil.

E. Fuelwater Partition Coefficient

The fuellwater partition coefficient (Kfw) expresses the extent to which an organic chemical partitions between the water (dissolved) phase and an organic (fuel) phase. The larger the fuellwater partition coefficient, the lesser the estimated concentration of a compound in water. This constant is useful in estimating the maximum expected dissolved concentration of a given component. In the environment, however, concentrations do not normally approach these

saturation concentrations due to other factors such as the adsorption coefficient. Fuellwater coefficients can be determined in the laboratory or estimated using solubility and/or adsorption coefficient data. Kfw is often determined using octanol as the fuel (Kow). The Kow values are less than the Kfw values determined using gasoline, although the relative values for the individual BTEX compounds are similar. The gasoline constituents with the lowest Kow values are the low molecular weight aliphatic and olefin compounds, while the highest Kow values are for the substituted aromatic compounds.

F. Degradation Half-life

A chemical's half-life (t1/2) is the time required for the chemical's concentration to be reduced to one-half of its original concentration. The processes responsible for the chemical's removal include degradation mechanisms from both biological and chemical reaction processes.

Degradation commonly results from biological consumption and breakdown, hydrolysis, oxidation/reduction, and photolysis. While it is possible to calculate a half-life for each individual removal mechanism, overall half-lives which account for the combined effects of one or more of each of these processes can also be calculated. Data are seldom available for each of the individual processes and it is necessary to estimate half-lives based on available data.

The half-lives are for degradation processes only and do not account for removal mechanisms such as volatilization and adsorption (Howard et al., 1991). Half-lives are available for both soil and groundwater environments. In both cases, biodegradation, and hydrolysis to a lesser extent, were determined to be the most important factors in the chemical's degradation. The soil half-lives for benzene and ethylbenzene were estimated based upon unacclimated aqueous aerobic microbiota degradation half-life while the soil half-lives for toluene, xylenes, and MTBE were based on acclimated aqueous aerobic microbiota degradation half-lives.

Groundwater half-lives for benzene and xylenes were based upon unacclimated aqueous aerobic (for low t112) and anaerobic biodegradation half-lives (for high t112). The groundwater half-life for toluene was based upon an unacclimated grab sample data of aerobic soil from groundwater aquifers. Groundwater half-life for ethylbenzene based upon sea water die-away test data (for high t112) and on unacclimated aqueous aerobic biodegradation half-life (for low tl l2). The groundwater half-life for MTBE was based on aerobic biodegradation half-life.

Aromatic compounds considered appeared relatively susceptible to microbial attack and subsequent degradation. Numerous factors such as temperature, nutrient availability, and sediment characteristics affect degradation. Petroleum products and mixtures may degrade differently than individual hydrocarbons in solution. Under certain environmental conditions, biodegradation increases when hydrocarbons are sorbed to suspended solids. There is also evidence which suggests that hydrocarbons must be in the dissolved phase in order to be degraded (API, 1988), and that some hydrocarbons cannot be biologically degraded completely (Alexander, 1985).

Characterization of Commonly Detected Contaminants

Due to the number of constituents detected, and the fact that many of these chemicals share common characteristics, the discussion below concerning the environmental fate and transport properties of various compounds addresses some individual compounds as well as representative groups of chemicals.

A. Aromatics

Benzene

Benzene released to the subsurface is subject to rapid volatilization, due to high vapor pressure, prior to contact with the water table. Benzene has a water solubility of 1,791 milligram per liter (mg/L) which causes it to be highly mobile in groundwater and is the most soluble of the BTEX compounds. Since solubility is inversely proportional to Kow it is not likely to adsorb onto soil or organic particles (Howard et al., Vol. 11, 1990). Benzene is subject to biodegradation based on reported rates of 24% to 47% of an initial 20 microgram per liter (pg/L) benzene concentration in a base-rich para-brownish soil in 1 and 10 weeks, respectively (Howard et al., Vol. 11, 1990). The highly volatile benzene does not persist long in the environment either in the atmosphere, groundwater or on soil particles. Its degradation rate depends on temperature, hardness of the groundwater and whether it is subject to aerobic or anaerobic conditions. Benzene is not expected to bioaccumulate in aquatic organisms (Howard et at., Vol. 11, 1990).

Toluene

Toluene released to the subsurface is subject to volatilization, due to high vapor pressure, prior to contact with the water table. Toluene has a water solubility of 534.8 mg/L which causes it to be mobile in groundwater and since solubility is inversely proportional to Kow, toluene is likely to adsorb only to a small extent of soil or organic particles (Howard et al., Vol.11, 1990). Since toluene is less soluble than benzene it is more likely to adsorb to soil or organic particles. Toluene is subject to biodegradation based on a report which showed 94% of the toluene added to a clay loam was lost to these processes (Howard et al., Vol.ll, 1990). Toluene is not persistent in the environment due to a relatively high degradation rate. The degradation rate depends on temperature, acclimation of microorganisms, hardness of the groundwater and whether it is subject to aerobic or anaerobic conditions. Toluene is not expected to bioaccumulate in aquatic organisms (Howard et al., Vol.11, 1990).

Ethylbenzene

Ethylbenzene released to the subsurface is subject to volatilization, due to a moderate vapor pressure, prior to contact with the water table. Ethylbenzene has a water solubility of 161 mg/L which causes it to be relatively mobile in groundwater and since solubility is inversely proportional to Kow, ethylbenzene is likely to adsorb onto soil or organic particles in small quantities (Howard et al., Vol. 1, 1989). There is little specific data on the extent of biodegradation of ethylbenzene in soil or groundwater, but it is expected to degrade slowly. Ethylbenzene has a low persistence in the environment and the degradation rate depends on temperature, acclimation of microorganisms, whether it is subject to aerobic or anaerobic conditions, the soil organic content and hardness of the

groundwater. Ethylbenzene is not expected to bioaccumulate in significant amounts in aquatic organisms (Howard et al., Vol. 1, 1989).

Para, Meta and Ortho-Xvlenes

Xylenes released to the subsurface are subject to volatilization, due to a moderate vapor pressure, prior to contact with the water table. Ortho-xylene has a water solubility of 175 mg/L which causes it to be relatively mobile in groundwater and since solubility is inversely proportional to Kow, ortho-xylene will have low to moderate sorption onto soil or organic particles (Howard et al., Vol. 11, 1990). Para-xylene degrades under aerobic conditions or under anaerobic denitrifying conditions. When para-xylene is released into an aerobic environment, 70% degradation has occurred within 10 days. When para- xylenes have been released into an anaerobic environment, a lag time of six months has been observed prior to the start of biodegradation (Howard et al., Vol. 11, 1990). Xylenes are moderately persistent in the environment and its degradation rate depends on temperature, concentration, residence time in the soil, the nature of the soil, whether resident microbial populations have been acclimated, whether it is subject to aerobic or anaerobic conditions and hardness of the groundwater. Para, meta, or ortho-xylenes are not expected to bioaccumulate in significant amounts in aquatic organisms (Howard et al., Vol. 11, 1990).

B. Ether

MTBE

MTBE is used in gasoline as an anti-knock agent and octane enhancer and has been since approximately 1979. The Environmental Protection Agency (EPA) allows as much as 11 % by volume MTBE in gasoline. The amount of MTBE in gasoline is dependent on the composition of the crude, octane rating of the distillate and the required octane rating of the final grade (Garrett et al., 1986). MTBE released to the subsurface is subject to rapid volatilization, due to extremely high vapor pressure, prior to contact with the water table. MTBE has a higher vapor pressure than any of the BTEX compounds. MTBE has a water solubility of 43,000 mglL which causes it to be highly mobile in groundwater, and since solubility is inversely proportional to Kow MTBE will have low sorption onto soil or organic particles (Garrett et al., 1986). MTBE has a higher solubility than aromatics, therefore it is less sorptive than aromatics. The presence of MTBE has been reported to increase the solubility of the BTEX compounds (Garrett et al., 1986). The persistence of MTBE is considered to be moderate due to its inability to biodegrade (Fujiwara et al., 1984). Based on limited data, MTBE is not expected to bioaccumulate in aquatic organisms or the food chain (Fujiwara et al., 1984).

C. Total Petroleum Hydrocarbons

Because TPH consists of a very large number of individual compounds, indicator compounds and/or compound groups are used to characterize the physical and chemical properties of the hydrocarbons. The volatile petroleum hydrocarbon (VPH) Method used in this Phase II separates the volatile hydrocarbons from the extractable hydrocarbons and uses the number of carbon atoms to distinguish the petroleum product(s) contributing hydrocarbons. The major components of petroleum hydrocarbons can be described as alkanes, alkenes, cycloalkanes and aromatics. VPH include C5-C8 aliphatics as well as C9-Cl I aromatics while the extractable petroleum

hydrocarbons (EPH) include C9-C18 and C19-C32 aliphatics and C12-C32 aromatics excluding the individual polycyclic aromatic hydrocarbons (PAHs) included as part of EPH's priority pollutants.

The alkanes (C5-C32) are also referred to as paraffins or saturated aliphatics and make up a significant portion of gasoline products. The alkenes (C9-C32) are also called unsaturated aliphatics or olefins. They are structurally similar to the alkanes with the exception of one or more double bonded carbons. Alkenes are a minor part of gasoline products. Cycloalkanes (C5-C32) are saturated cyclic compounds also referred to as naphthenes. Aromatic (C6-C32) compounds are cyclic and unsaturated and characterized by one or more benzene ring. When many benzene rings attach they form the class of compounds known as PAHs. In general, as carbon number increases the molecular weights increase and consequently the boiling points increase. Other petroleum products can be classified by the following: carbon chains, jet fuel (C5-C16), number two fuel oil or diesel fuel (C10-C20), and number six fuel oil (C12-C32).
