INTRODUCTION CDM Federal Programs Corporation (CDM Smith) received Work Assignment 040‐RICO‐023J under the United States Environmental Protection Agency (EPA) Region 2 Remedial Action Contract (RAC2) number EP‐W‐09‐002 to perform a Remedial Investigation/Feasibility Study (RI/FS) at the Pohatcong Valley Groundwater Contamination (PVGWC) site, Operable Unit 3 (OU3) (the site). The OU3 RI field investigation was completed in April 2012. Supplemental sampling events were conducted in March 2013 to refine the extent of the contamination within the onsite properties. Because of concerns regarding the reliability of select analytical results for previously collected RI soil, groundwater, sediment and surface water samples, environmental samples are proposed to be re‐collected from previously sampled locations in support of the RI/FS and the associated risk assessments. Sampling locations include the Albea Americas, Inc. (Albea) property (formerly the American National Can property) and all the adjacent properties, including Warren Lumber Yard (WLY), Vikon Tile Corporation (VTC), Area of Concern 1 (AC 1) and the railroad right‐of‐way. This document is Addendum No.3 to the Final Quality Assurance Project Plan (QAPP) for the Pohatcong Valley Groundwater Contamination Superfund Site Remedial Investigation/Feasibility Study (RI/FS) dated June 7, 2011, and documents the resampling soil investigation as outlined in the Work Plan Letter dated October 8, 2014 (CDM Smith 2014) and approved by EPA. The following tasks will be performed during the revised remedial investigation: Collection of soil samples from 4 deep soil borings beneath the Albea building in the area of the
former molding room and advanced to the water table (~125 feet [below ground surface] (bgs) using rota‐sonic drilling methods. Two soil samples will be collected from the initial 10 feet (0 to 2 and 5 to 7 feet) and then every 10 feet to depth based on field observations. Groundwater screening samples (GSS) will be collected from the deep water table, if field observations indicate contamination at or above the water table.
Collection of soil samples from 17 exterior deep soil borings on the Albea and adjacent properties (13 onsite, 1 background and 3 contingency) advanced to the water table or bedrock surface (~100‐125 feet bgs) using rota‐sonic drilling methods. Soil samples will be collected as described in the previous bullet, GSS will also be collected from the deep water table, if field observations indicate contamination at or above the water table.
Collection of soil samples from 24 (21 onsite and 3 contingency) exterior shallow soil borings within the drainage pathway on the Albea and adjacent properties, advanced to approximately 40 feet bgs using geo‐probe drilling methods. Soil samples will be collected as described in the first bullet. GSS will be collected from the perched groundwater.

Comments/Decisions: CDM Smith and EPA reviewed and discussed the proposed resampling scope. Modifications to scope included:
As confirmed with the EPA project risk assessor, other organics analyses are not needed at depth for the human health and ecological risk assessments. However, analysis of other organics is required to complete a full CERCLA RI. Therefore, the approach used in the original RI sampling approach (30 – 40% of samples analyzed for other organics) will be included in the resampling scope. All previous organics analyses will be resampled during this program.
Human Health Risk Assessment, Screening Level Ecological Risk Assessment and RI Reports – EPA confirmed that all questionable organics data must be replaced with the new data. EPA also stated that a statement will be required in the introduction as to why the data was replaced, and CDM Smith should edit the text, tables and figures as necessary, re‐evaluate conclusions and recommendations and reissue new reports. Both draft and final version will be prepared.
FS Report ‐ After validation of resampling data, all recently collected data (RI resampling, supplemental sampling and vapor intrusion (VI) data related to investigation, remediation and Operations & Maintenance data) will be re‐evaluated and a meeting to determine how to move forward on the FS will be convened.
Access Agreements –EPA requested CDM Smith provide a status of the access agreements, including a summary of actions needed for resampling access. EPA to contact Office of Regional Counsel to move access forward as soon as possible.
Action Items: Upon finalizing the work plan letter, CDM Smith will coordinate with the facility owner to discuss access. An additional logistics/coordination meeting will be held with the facility owner prior to mobilization.

QAPP Worksheet #10 Problem Definition
Problem Summary Concerns regarding the reliability of all organic (VOCs, SVOCs, PCBs and pesticides) analytical results for soil, groundwater, sediment and surface water previously received in conjunction with the RI/FS, environmental samples are proposed to be re‐collected from previously sampled soil, groundwater, surface water and sediment locations in support of the RI/FS and the associated risk assessments. Project Description The investigation will include soil, groundwater, surface water and sediment sampling in and around the Albea Americas, Inc. (Albea) property (formerly the American National Can property (ANC)) and all the adjacent properties, including Warren Lumber Yard (WLY), Vikon Tile Corporation (VTC), Area of Concern 1 (AC 1) and the railroad right‐of‐way. Project Decision Conditions Soil field screening data (from a photo ionizing detector) and quick turnaround time analytical results will be evaluated and reviewed with EPA throughout the program to determine if additional sampling is required to refine the extent of contamination of soils at the site. Three deep and three shallow contingency borings are built into the program to be used if additional sampling is needed.

QAPP Worksheet #11
Project Quality Objectives/Systematic Planning Process Statements following order: EPA’s Region 2 Division of Environmental Science and Assessment (DESA) laboratory, an EPA Contract Laboratory Program (CLP) laboratory, or a CDM Smith subcontract laboratory. Data must meet the data quality objectives that have been specified for the site. Where, when, and how should the data be collected? The samples will be collected from locations shown on Figure 2. Worksheet #17h and Table 1 presents the sampling program design, rationale, sampling procedures and analytical parameters. Locational data will be documented by hand measurement from known interior features. Who will collect and generate the data? CDM Smith will collect the analytical samples that will be shipped to DESA, CLP, and/or CDM Smith’s subcontract laboratory for analysis.
How will the data be reported? Validated analytical data will be downloaded from EPA’S website or forwarded to CDM Smith from a subcontract laboratory for evaluation and use in the Supplemental Investigation Report and FS. Analytical data generated by a laboratory under subcontract to CDM Smith will be received in electronic and hard copy and validated by CDM Smith personnel. Following completion of all laboratory analysis and receipt of all electronic and hard‐copy data, the Supplemental Investigation Report will be generated by CDM Smith and submitted to EPA with tabulated data. CDM Smith will use global information system (GIS) to facilitate spatial analysis of data to generate figures for reports and presentations. How will the data be archived?
Data from a subcontract laboratory will be received in EPA Region 2 electronic format and validated Final DESA or CLP validated data will be submitted to CDM Smith in electronic format and hard copy Electronic data will be input into the project's EQuIS database EPA will archive CLP laboratory raw data Hard copies of analytical data received by CDM Smith will be archived in the project files for 10 years after contract expiration

QAPP Worksheet #14 Summary of Project Tasks
Sampling Tasks: Sampling tasks are summarized on Table 1 and 2 below: Analysis Tasks: See Table 1 Quality Control Tasks: Field blanks and field duplicates will be collected as described on Worksheet #20. MS/MSDs will be collected if samples are assigned to the DESA laboratory. Secondary Data: Secondary data listed in Worksheet #13 in the Final QAPP (June 2011) and results from the 2013 Supplemental Soil Sampling event and the 2013 vapor intrusion sampling event were reviewed and used to plan sample locations. These results were added to the project database. These data were validated and found to be useful for its intended use. Only valid data were included in the data evaluation. Data Management Tasks: Analytical data will be imported into the Environmental Quality Information Systems (EQuIS) database after validation. Field measurements will also be added to the database.
All final laboratory data will be submitted to CDM Smith in electronic format consistent with CLP deliverables. The Analytical Service Coordinator (ASC) will review all analytical data.
Hard copies of analytical data received by CDM Smith will be archived in project file. Electronic data will be uploaded into the CDM Smith Database system. Electronic data will be consistent with EPA Region 2 requirements for electronic data deliverable (EDDs). Electronic analytical data will be archived on CDs and copies of CDs will be forwarded to the EPA.
CDM Smith’s Field Team Leader is responsible for tracking all samples from the point of collection to shipment for laboratory analysis. The data coordinator is responsible for tracking samples from shipment for laboratory analysis to the subsequent data validation and data management efforts. The sample handling and custody requirements, including field log books and generation of sample paperwork, sample labels, and custody seals discussed in Worksheets #26 and #27 of Final QAPP (June 2011), will be followed according to TSOP 1‐2. The analytical services coordinator (ASC) or data coordinator will receive non‐routine analytical services (non‐RAS) data from the laboratory(s) and will track it through the data validation process. For non RAS data, the ASC will submit the electronic “Analytical Services Tracking System Data Requirement” form (Appendix C of Final QAPP [June 2011]) to the Regional Sample Control Center by the first day of each month for the previous month’s sampling.

QAPP Worksheet #14 Summary of Project Tasks
CDM Smith will be responsible for tracking and maintaining custody of the laboratory data packages through the data validation process. Data validation will be in accordance with the procedures described in Worksheets #35 and #36 of the RAC2 Region 2 Generic QAPP (December 2013). Once the data is validated, it will be input into CDM Smith’s database.
A project electronic spreadsheet using Scribe software will be developed for sample tracking purposes prior to field activities. The tracking system will be initiated in the field during sample collection and will be updated during the sample analysis and data validation phases. The data will be entered by project staff and then checked by the data coordinator for accuracy and to document changes to sample locations or samples which are not collected due to field conditions. This tracking system will ensure that no data is lost during the data management process. The following information is recorded in the tracking system:
Area of Concern (sample location area) Sample Matrix SDG Number CLP Case No. CLP No. Analytical Parameter Collection Date Shipment Date
Sample Number Date Received from Lab Date Submitted for Data Validation Name of Data Validator Date of Data Validation Completion Database Entry Date Database QC Date Comments (i.e., duplicate samples).
Analytical data collected during the field effort will be entered into EQuIS. This data management system will also include location data. The database management system will provide data storage, retrieval, and analytical capabilities. The system will be used to support report preparation by providing data users the data they need to complete their work using spreadsheets, word processing, statistical, and graphics software. To facilitate the use of the database, CDM Smith will provide subcontract laboratories with the specifications for the EPA Region 2 analytical data EDD. Once it is uploaded into the database, validated analytical data will be used in the data evaluation phase. A 100 percent quality control check will be performed to ensure accuracy on all hand‐entered data (i.e., data qualifiers added by CDM Smith validators on subcontract laboratory data, sample field notations). Data tables that present the results of the sampling program will be prepared and compared to applicable screening criteria. Graphics and GIS software will be used to present sample results and illustrate contaminants detected.
Pohatcong Valley Groundwater Contamination Superfund Site, OU3
QAPP Worksheet #14 Summary of Project Tasks
As a quality control check, reports, tables, and graphical figures will be compared to source material from the database to check for errors and omissions. CDM Smith will provide EPA with final analytical data as part of the Region 2 EDD requirement. The EQuIS data base system will be the primary data management system software. This software is managed on CDM Smith’s computer network in compliance with software licensing requirements. Access to the project database is limited to authorized personnel only via their computer. CDM Smith will take reasonable care to protect the data and will perform periodic backups to prevent wholesale loss of project data. Control of the computer hardware and software will be as per CDM Smith’s quality procedure 4.1. After CLP data is validated, the package is returned to the EPA regional project manager. The original CLP data packages with all associated forms are retained by EPA for archival. Non‐CLP data packages received from a laboratory subcontractor will be validated by CDM Smith’s ASC or designee. These packages are stored in electronic format on CDM Smith’s computer network where they are accessible to the project manger and other team members. Copies of the non‐CLP data packages, in electronic format, will be submitted to EPA (as directed) during project close‐out. Documentation and Records: Information regarding samples will be recorded in site field logs. Any changes that are made to the field logs shall be initialed and dated. Documents will be maintained in the project files and/or the RAC 2 document control system. Chain‐of‐Custody (COC) forms and FedEx air bills will also be completed for the sampling event. The results of this field investigation will be presented in the Revised Remedial Investigation Report (RRIR).

QAPP Worksheet #17h Sampling Design and Rationale Revised Remedial Investigation
Describe and provide a rationale for choosing the sampling approach: Concerns regarding the reliability of select analytical results for soil, groundwater, sediment and surface water previously received in conjunction with this RI/FS, environmental samples are proposed to be re‐collected from previously sampled locations in support of the RI/FS and the associated risk assessments. Sampling locations include the Albea Americas, Inc. (Albea) property (formerly the American National Can property) and all the adjacent properties, including Warren Lumber Yard (WLY), Vikon Tile Corporation (VTC), Area of Concern 1 (AC 1) and the railroad right‐of‐way. The borings are summarized on attached Table 1, while Figure 2 shows the proposed soil boring locations. Table 2 provides the sampling rationale for each location. Sampling Design: The number and selection of locations were selected upon review of the unreliable data. All sample naming schemes are detailed in the Final QAPP (June 2011). Sample locations names will be modified starting with the 200 to identify them as being from this investigation. The revised remedial investigation events are detailed below. Shallow Soil Borings A total of 24 shallow borings will be advanced to approximately 40‐feet bgs during this event (21 plus three contingency. A 2‐inch ID macro‐core sampler will be advanced to depth. Lithologic samples will be collected continuously using a 4‐foot long macro‐core sampler with lexan liners. Upon retrieval from the sampler, each 4‐foot sample will be opened by the driller and screened for VOCs using a photo‐ionization detector (PID) by the field geologist. The lithology of each sample will be characterized and logged by the field geologist. The sampling and lithologic logging procedures are detailed in the TSOPs 1‐4 and 3‐5 (field copy will have all required TSOPs). It is assumed that up to six soil samples will be collected from each of the 40‐foot soil borings. Samples will be analyzed as described in Table 1. All borings will at least be sampled at a depth of 0 to 2 feet and 5 to 7 feet. The depth of the remaining samples will be selected in the field based on visual observations, highest PID screening results, and to provide proper vertical coverage. Perched Groundwater Sampling Following completion of the soil borings a DPT drill rig will be used to collect up to 15 groundwater screening samples from the perched groundwater zones. Samples will only be attempted in zones that show significant evidence of perched groundwater. Adjacent to the original borehole locations, the DPT rods will be advanced to the sampling depth first, and a four‐foot screen will be exposed to the formation. Prior to sampling, the screen will be briefly developed using a peristaltic pump (or a check valve if depth to groundwater is too great) to clear the screen and formation of silt and fine‐grained particles. Following a brief development of no longer than 30 minutes, a grab sample of the groundwater will be collected. If the screening samples collected contain excessive amounts of sediment, CDM will work with the laboratory and the driller to revise the approach. Contingencies could include changing the type or size of the sample bottles, additional development of the screen interval or alternative sampling methods. The CDM Smith RQAC will check that all DQOs can be met by the alternative sampling methods. Field parameters including pH, conductivity, temperature, DO, ORP, and turbidity will be measured at the time of sampling. If the perched zone does not provide sufficient water for a sample then a sample will not be collected. Samples will be analyzed for TCL Trace level VOCs.
Pohatcong Valley Groundwater Contamination Superfund Site, OU3
QAPP Worksheet #17h Sampling Design and Rationale Revised Remedial Investigation
Deep Facility Soil Borings A total of 4 deep borings will be advanced to approximately 125‐feet bgs during this event below the facility. Sonic drilling methods were selected. Due to height constraints, exhaust and dust control issues, sonic drilling is the cleanest drilling method with the capabilities of collecting samples in the geologic materials at the site. To advance each of the deep soil borings through the facility floor an appropriate sized concrete hole will be cut through the floor using a concrete coring tool. Following concrete coring a 4‐inch diameter casing will be advanced to depth using a mini‐sonic drill rig. Lithologic samples will be collected in 10‐foot sections using the 4‐inch lead casing. Upon retrieval from the sampler, each ten‐foot sample will be screened for VOCs using a photo‐ionization detector (PID). The lithology of each sample will be characterized and logged by the field geologist. The sampling and lithologic logging procedures are detailed in TSOPs 1‐4 and 3‐5. At each interior deep soil boring, subsurface soil samples will be collected at 0 to 2 feet, 5 to 7 feet, and every 10 feet from 10 feet bgs to a total depth of approximately 125 feet bgs. The goal of the sampling being to collect a soil sample from each ten‐foot depth interval. Exact sample depths will be selected in the field based on results of the field screening with the PID. Each boring will be advanced to the top of bedrock or into the regional groundwater table (water levels in nearby wells will be reviewed by the field crew to gain an understanding of the depth of the regional water table), whichever is encountered first. It is assumed that up to 14 soil samples will be collected from each of the deep soil borings as described above. Each soil sample will be analyzed for TCL VOCs and moisture content. In addition, at up to five of the sampling intervals additional soil volume will be analyzed for TOC, grain size, TCL SVOCs, PCBs and pesticides. The additional parameters will be collected at the 0 to 2 feet (surface soil) and 5 to 7 feet soil samples and 30 percent of the subsurface soil samples (assumed to be the 30, 60 and 90‐foot samples). The depth of the samples will be selected in the field based on visual observations and PID screening results. A summary of the analyses proposed for each boring type is presented on Table 1. If contamination is observed in deep soils (via PID) a groundwater grab sample will be collected at the base of each boring within the regional groundwater table. If bedrock is encountered before the regional groundwater table then a sample will not be collected at that location. Groundwater screening samples will be collected by advancing the 4‐inch casing to depth. Once at depth, a stainless steel bailer will be lowered to the bottom of the casing to grab a sample for trace TCL VOCs. Deep Exterior Soil Borings A total of 17 deep borings (14 plus 3 contingency) will be advanced to approximately 100 to 125‐feet bgs during this event. Sonic drilling methods were selected in order to reach the proposed depths in this area as the glacial geology has proven to be difficult to penetrate during previous investigations. Lithologic samples will be collected in 10‐foot sections using the 4‐inch lead casing. Upon retrieval from the sampler, each ten‐foot sample will be screened for VOCs using a photo‐ionization detector (PID). The lithology of each sample will be characterized and logged by the field geologist. The sampling and lithologic logging procedures are detailed in TSOPs 1‐4 and 3‐5. At each deep exterior soil boring, subsurface soil samples will be collected at 0 to 2 feet, 5 to 7 feet, and every 10 feet from 10 feet bgs to a total depth of approximately 125 feet bgs. The goal of the sampling being to collect a soil sample from each ten‐foot depth interval. Exact sample depths will be selected in the field based on results of the field screening with the PID.

QAPP Worksheet #11 Project Quality Objectives/Systematic Planning Process Statements
Overall Project Objectives The revised RI will include soil, groundwater, surface water and sediment sampling below, adjacent to and in the drainage areas surrounding the Albea facility for the analyses presented below to replace unreliable data provided in the previous remedial investigation.
Who will use the data? EPA and CDM Smith will use the data.
What type of data are needed? The sampling program will include the following:
Soilo Shallow Soil Samples: Trace level TCL VOCs by SOM01.2 (with a 7‐day turnaround time [TAT] for the onsite samples).
TLC SVOCs, PCBs and Pesticides by SOM01.2 (42‐day TAT)
o Deep Facility Soil Samples: TCL VOCs by SOM01.2 (with 48‐hour TAT)TCL SVOCs, PCBs and Pesticides by SOM01.2 (42‐day TAT)
o Deep Exterior Soil Borings: TCL VOCs SVOCs, PCBs and Pesticides by SOM01.2 (42‐day TAT)
o Deep Facility Soil Borings: Trace level TCL VOCs SOM01.2 (42‐day TAT)
Surface Water: TCL VOCs, SVOCs, PCBs and Pesticides by SOM01.2 (42‐day TAT)
Sediment: TCL VOCs, SVOCs, PCBs and Pesticides by SOM01.2 (42‐day TAT)
What will the data be used for? Data will be used to replace unreliable data reported in previous remedial investigation.
How “good” do the data need to be in order to support the environmental decision? Definitive level data required to support project decisions and risk assessments. The project action limits and quantitation limits for soil VOCs are specified on Worksheet #15. All laboratory analyses will be performed in compliance with EPA’s Field and Analytical Services Teaming Advisory Committee policy. Preference will be given in the

(surface soil) and 5 to 7 feet soil samples and 30 percent of the subsurface soil samples (assumed to be the 30, 60 and 90‐foot samples). The depth of the samples will be selected in the field based on visual observations and PID screening results. A summary of the analyses proposed for each boring type is presented on Table 1.
If contamination is observed in deep soils (via PID) a groundwater grab sample will be collected at the base of each boring within the regional groundwater table. If bedrock is encountered before the regional groundwater table then a sample will not be collected at that location. Groundwater screening samples will be collected by advancing the 4‐inch casing to depth. Once at depth, a stainless steel bailer will be lowered to the bottom of the casing to grab a sample for trace TCL VOCs.
Bore Hole Abandonment After sampling, the boreholes will be backfilled with a cement‐bentonite grout. Borings completed using HSA or sonic drilling methods will be grouted using tremie pipe to grout from the base of the borehole as the drilling tools are retracted. Borings completed using DPT methods will be abandoned by filling the borehole with grout upon completion.
Surface Water and Sediment Sampling Following the site reconnaissance, locations will be selected for surface water and sediment sampling. The locations will focus on drainage ditches, outfalls, seeps, drainage pipes and areas of ponded water. Up to 14 surface water and sediment samples will be collected as part of this RI.
Surface water samples will be collected following EPA‐approved methodologies as described in TSOP 1-1. All surface water samples will be analyzed for TCL VOC and TCL pesticides/PCBs through the EPA CLP. All samples will be analyzed using the most current EPA‐approved methods, as shown on Worksheet 18. Table 1 summarizes the number and type of analyses for the surface water samples.
Sediment samples will be collected following EPA‐approved methodologies as described in TSOP 1-11. All sediment samples will be analyzed for TCL parameters through the EPA CLP as summarized on Table 1.
