Groundwater Investigation Plan for Operable Unit 2 Bennett's Dump, Bloomington, Monroe County, Indiana
1.0 BACKGROUND
This report summarizes the results of groundwater, surface water, flow and water level monitoring work completed by CBS Corporation during the fourth quarter of2014 at the Bennett's Dump site. The work was performed for the purpose of assessing the feasibility of capturing PCB-contaminated shallow groundwater and to support the engineering design of an effective capture and treat system.
Monitoring activities in accordance with the December 2009 Final Bennett's Dump Groundwater Investigation Plan for Operable Unit 2 (GWIP) were performed at surface water and groundwater locations including test pits, quarries, piezometers, monitoring wells, springs and streams as summarized in Table 1.
The Bennett's Dump Groundwater Investigation Plan comprises different monitoring schemes for the periods before and after construction of the Passive Quarry Drain. Pre-quarry drain construction monitoring activities Were performed until completion of the quarry drain at the beginning of September 2010. The post-quarry drain monitoring program includes all of the locations and monitoring requirements formerly prescribed by the Long Term Groundwater Monitoring Plan (LTGMP). Therefore, quarterly reporting under the GWIP will replace L TGMP reporting, pending the development and approval of a final L TGMP.
2.0 SURFACE WATER MONITORING
The three month period October-December, 2014 constituted the fourth reporting quarter of2014 for the Bennett's Dump site. The monitoring work described in this report was performed December 11, 2014.
November 23, 2015 Page2
Scope of Work
The scope of water sampling for October-December 2014 comprised collecting samples at Stout's Creek Upstream and Downstream stations, Middle Spring, Rusty Spring and Icebox Quarry. Mound Spring, North Spring and Mid-North Spring were not flowing during the fourth quarter sampling event.
Sample Collection and Handling
Samples at the spring and stream locations were collected by carefully filling a new disposable beaker. The water was transferred from the beaker into pre-cleaned amber glass I-liter bottles supplied by the analytical laboratory. Routine sampling parameters including temperature and conductivity were measured and recorded.
Samples were analyzed by Pace Analytical Lab of Indianapolis, Indiana. The samples were analyzed to a detection limit of 0.1 parts per billion (ppb) for all PCB parameters by EPA SW-846 method 8082. Stout's Creek samples are analyzed to a detection limit of 0.01 ppb. Samples were also analyzed for total suspended solids (TSS) by method SM2540 D.
Quality Assurance
For quality assurance purposes a duplicate sample and a field blank were collected during each sampling event. All environmental and blank samples were labeled and logged onto a chain of custody form. The samples were stored and transported on ice in insulated coolers. Custody of the water samples was maintained by CBS until shipment to the analytical laboratory.
The field blank sample for the 2014 fourth quarter sampling event was BD 11031. No PCBs were detected in this sample.
Analytical Results for Surface Water Samples
Field parameter measurements, PCB analytical results, and QA/QC results for surface water samples collected during this reporting period are reported in Tables 2 through 9. Each table summarizes historical groundwater monitoring data collected since the completion of Passive Quarry Drain in September 2010.
Copies of the chain of custody forms are provided in Appendix A. Copies of the certificates of analysis are provided in Appendix B. A validation summary for these samples appears in Appendix C. Copies of the field sampling data sheets are on file at PSARA's Bloomington Branch Office.

3.0 FLOW AND WATER LEVEL MONITORING
The purpose of flow and water level monitoring is to evaluate site-specific data characterizing site hydrologic response under storm and non-storm conditions, and to evaluate correlations between PCB concentrations, spring flow and groundwater elevations. The goals are to assess the feasibility and support the engineering design of a system to capture and treat Middle Spring flows and nearby shallow groundwater.
Scope of Work
The scope of groundwater level and flow monitoring during this reporting period involved numerous manual measurements and observations, as well as the use of dedicated instrumentation to record water level and other parameters as summarized in Table 10. Since the completion of the Passive Quarry Drain, Mound Spring flow occurs only during wet periods and after large rainfall events. When persistent flow is observed at Mound Spring, an instrument is installed at the weir pool.
The approximate locations of the stations are shown on Figure 1.
Flow and Water Level Plots
Middle Spring flowed intermittently during the fourth quarter. Mound Spring was not observed to flow during the fourth quarter. Manual observations made at Mound Spring were added to the plots of Middle Spring flow.
Flow observations at on-site springs also are presented in Table 11. An Excel spreadsheet file, including water level and flow observation data, accompanies this report as an attached file: BD GWIP Water Level Observations with plots - Q4 2014.xlsx.
Quality Assurance
An instrument maintenance log for the Bennett's Dump installations is provided in Appendix D. This log details the installation, re-indexing, and maintenance histories of the data logging equipment present at Bennett's Dump during the reporting quarter.
Crest Gauges
The purpose of the crest gauges at Middle Spring and Mound Spring is to provide an indication of maximum flow during each reporting period. Maximum recorded water levels and flows estimated from these data are presented in the instrument maintenance log in Appendix D.
November 23, 2015 Page4
Potentiometric Data
Potentiometric contours shown on Figure 1 were developed based on water level measurements taken on December 11, 2014. The specific water level measurement locations are listed in the table insert on Figure 1.
If you have questions regarding the sampling and flow/water level monitoring activities or findings for this reporting period, please call Neill Vaughan at (812) 335-0424.

Data Validation
Validation Results December 11, 2014
Bennett's Dump SDG #50109036
Groundwater Monitoring Samples
1. Validation of the following sample has been completed:
• BD11027 thru BD11033
2. Validation was performed per the requirements for level 4 data in the project QAPjP. This includes a check for; Holding Time, Calibration, Blank Contamination, Precision, Accuracy, and Accuracy of Nominal Reporting Limits against method requirements.
3. Based on this review no data qualifications are recommended.
4. The QAPjP requires an assessment of the overall data quality with respect to Precision, Accuracy, Representativeness, Completeness and Comparability (PARCC).
o Precision and accuracy: Precision and accuracy were accessed by reviewing the lab performance on lab spiked samples, lab spike duplicates and field duplicates. All requirements were met.
o Representativeness: The representativeness requirement involves an assessment of the field sampling and lab analytical techniques. The field sampling locations and techniques as well as lab procedures were in accordance with the approved sampling plan and QAPjP. Therefore the representativeness requirements were met.
o Completeness: The completeness goal for the project was for all project data to be 90% accepted. Completeness is calculated by dividing the total number of acceptable analyses by the total performed. An acceptable analysis is defined as one that conformed to QC protocols and is not rejected. All these analyses were accepted. The project completeness goal has been met to date.
o Comparability: All the samples taken, analyzed and validated by CBS were taken by CBS or it's contractors sampling crews using the same procedures as previous samples at this location. These samples were analyzed by Heritage Labs. Care should be taken when attempting to trend Heritage sample results with other labs using slightly different procedures. Overall these results should be directly comparable to other Heritage lab results from these locations.
Overall, the main objective of the sampling event was to determine if PCBs are present at a concentration of .1 ppb or more (0.01 ppb for Stout's Creek Downstream, SCD and Upstream, SCU). This data is of sufficient quality to satisfy this goal.
