MOM 2012 Annual Report 

# EXECUTIVE SUMMARY
This report presents the results of the sampling and analysis of the April 2012 annual groundwatermonitoring program conducted at the O’Connor Superfund Site (Site) in Augusta, Maine. Representatives from Central Maine Power Company (CMP) and Woodard & Curran (W&C) performed this work on April 25, 2012. The sampling was conducted in accordance with the sampling methodology contained in the O’Connor Site Management of Migration (MOM) Groundwater Monitoring Program Sampling and Analysis Plan (SAP) dated December 1996 (Revision 4) with amendments. The O’Connor Site was the former location of salvage processes, including stripping and recycling transformers that contained polychlorinated biphenyl (PCB)-laden oil. As a result of uncontrolled releases of PCBs, lead, carcinogenic polynuclear aromatic hydrocarbons (cPAHs), and volatile organic compounds (VOCs) at the Site, the Site was placed on the National Priorities List. Site remediation conducted to date has included the installation and operation of a vacuum enhanced product recovery (VER) system (1996-1997, 2001-2004, and 2006), Source Control (1996-1997), and ongoing passive oil recovery from observation wells in the former transformer work area II (TWA II). Analytical results for this sampling event and previous sampling events are summarized in this report. The groundwater sampling and analysis results obtained during this sampling round will be used to supplement previous groundwater data collected at the Site. This report compares the April 2012 groundwater quality data to the groundwater performance standards specified in the 2002 Record of Decision (ROD) Amendment and 2003 Statement of Work (SOW). These performance standards are chemical-specific Applicable or Relevant and Appropriate Requirements (ARARs) based on United States Environmental Protection Agency (USEPA) Maximum Contaminant Levels (MCLs) and Maine Maximum Exposure Guidelines (MEGs). The purpose of these comparisons is to evaluate the level of compliance with the clean up standards for the target compounds. A review of the results of the April 2012 sampling and the historic groundwater data at the O’Connor Site has led to the following conclusions and recommendations:

 There were no exceedances of groundwater performance standards for the eight VOCs analyzed for in the MOM monitoring wells in April 2012. VOCs were detected in three out of nine wells sampled and were well below the groundwater performance standards.

 The concentrations of 1,4-dichlorobenzene in groundwater in the MOM wells are trending downward.

 PCBs were not detected in MOM monitoring wells in April 2012. The amount of oil removed from the wells using the VER system has decreased steadily over time. In the fall of 2006 the VER system was shutdown because the rate of oil recovery using passive recovery was equal to or greater than with the VER system. The passive oil recovery program will continue on a quarterly basis.Central Maine Power (225545) 1-1 December 2012

MOM 2012 Annual Report 

# 1. INTRODUCTION
1.1 PURPOSE AND OBJECTIVES This document is the annual Sampling and Analysis Report for the MOM component of the Remedial Design/Remedial Action at the Site located in Augusta, Maine. The requirement for a long-term groundwater quality-monitoring program was established by the USEPA in the ROD, December 27, 1989 for the Site. In 2002, a ROD Amendment was signed that revised the original remedy. The ROD Amendment established a waiver of ARARs, federal and state drinking water standards, for a limited portion of the Site (including the TWA II Area) on the basis of technical impracticability. The ROD Amendment also revised the ARARs to include a total of eight VOCs and PCBs. The TI waiver applies to these ARARs within the TI zone of the Site, shown in Appendix A. The 2003 SOW incorporates the revised ARARs as groundwater performance standards. The primary objective of this report is to document the April 2012 groundwater sampling event and present the analytical results. Work was performed in accordance with the MOM SAP dated December 1996 (Revision 4) with amendments. This report satisfies the submittal requirements under Section I.3.b. (1)(c) of the revised SOW dated October 20, 1994. There were no additional submittal requirements in the 2003 SOW. W&C assisted CMP in implementing the MOM water quality-monitoring program. Groundwater samples were collected from the nine MOM monitoring wells listed below. The locations of these wells are shown in Appendix A. Groundwater Monitoring Wells

MW-104B MW-501 MW-507A MW-106A MW-502 MW-508B MW-106B MW-503 OW-201B

The groundwater data from these samples provide current groundwater quality data for the ongoing MOM monitoring program. The April 2012 groundwater quality data has been compared with data collected from previous groundwater monitoring events. This groundwater data set will be used to identify if any areas of the Site are not currently meeting groundwater performance standards. In addition, this data will be used to identify groundwater quality trends for each specific sampling location.


## 1.2 SUMMARY OF PREVIOUS GROUNDWATER INVESTIGATIONS Two significant groundwater migration pathways have been identified at this Site during previous studies. The till/bedrock interface is the primary migration pathway of contaminants. The secondary migration route is within the fractures in the bedrock. The monitoring wells with an “A” designation and MW-501, MW-502 and MW-503 monitor the primary till/bedrock migration pathway; whereas the monitoring wells with a “B” designation monitor the fractured bedrock aquifer. For a more detailed discussion of the current hydrogeologic understanding of the Site, refer to Section 2.4 of the Draft Proposed Final MOM Remedy report (12/97) or the June 2002 TI waiver Evaluation Report.Central Maine Power (225545) 1-2 December 2012

MOM 2012 Annual Report 

### A comprehensive evaluation of the available groundwater analytical data from the Site was completed in August 1997. The results of the MOM comprehensive evaluation indicated that the contaminants were not continuing to migrate in groundwater and the contaminant levels in groundwater were not increasing. PCB’s had not been detected in any of the MOM monitoring wells from May 1996 through September 1997 and, therefore; PCBs were not believed to be mobile in the groundwater flow system. Continued monitoring has proven that no PCBs are migrating in the groundwater monitored in the MOM monitoring program. The groundwater data suggested that contaminants are not moving in the principle till/bedrock migration pathway due to low hydraulic conductivity. For a complete summary of historic groundwater analytical results, refer to the MOM Comprehensive Evaluation (June 1997). Additionally, the Draft Proposed Final Management of Migration Remedy report also summarizes the existing contaminant distribution at the Site. Two groundwater-monitoring wells (MW-507A and MW-508B) were installed at the Site southeast of TWA-II in October 1997. The location of these two wells is shown in Appendix A. These wells were installed to evaluate the groundwater within the area of the previously identified bedrock trough. These two wells monitor different depth, zones (overburden and bedrock) at the same location. Monitoring well MW-507A is a shallow well and is screened (approximately 10-20 feet below the ground surface) in the till soils immediately above the bedrock surface. Monitoring well MW-507A is constructed with a bentonite seal above the screen to prevent the vertical migration of surface water into the well. Monitoring well MW-508B is a bedrock well screened 32-42 feet below the top of the PVC riser to monitor the groundwater in the bedrock flow system. The depth of the screen zone in MW-508B was chosen based upon an inspection of the bedrock cores collected during the drilling. MW-508B is constructed with bentonite chips and a bentonite grout seal above the screen so that only the bedrock groundwater will be available to recharge the well during purging and sampling. The groundwater recharge to this well is very slow indicating a bedrock aquifer with low hydraulic conductivity. Three monitoring wells, MW-509A, MW-510A and MW-511A and a piezometer MW-512A, were installed north and west of TWA-II in July 2001. These wells were installed to provide additional monitoring points for groundwater quality and groundwater elevation in the MOM monitoring network. Piezometer MW-512A was installed to gather additional groundwater elevation data from the site. These wells and piezometer were decommissioned on September 2, 2008. Decommissioning activities are detailed in the Monitoring Well Decommissioning Summary (October, 2008).Central Maine Power (225545) 2-1 December 2012

MOM 2012 Annual Report 

# 2. SAMPLING PROCEDURES
During the April 2012 sampling event, groundwater samples were collected from the nine MOM monitoring wells at the Site. Prior to the sampling activities each day, a health and safety meeting was conducted for the field personnel. Health & Safety topics specific to the O’Connor site were presented and discussed. The health and safety meetings are documented in the field notes for each work day. The April 2012 monitoring event was completed without a health and safety incident.


## 2.1 GROUNDWATER PURGING AND SAMPLE COLLECTION The MOM groundwater monitoring wells were purged and sampled on April 25, 2012, using low-flow purging and sampling techniques. Two MOM monitoring wells (MW-104B, and OW-201B) were sampled with Grundfos Redi-Flo2 dedicated submersible pumps. The other MOM monitoring wells were sampled with a Masterflex or Geopump peristaltic pump and dedicated tubing. The depth to groundwater and total depth of each well were measured at each well. The depth to groundwater and groundwater elevations are included in Appendix B. Turbidity, pH, specific conductance, dissolved oxygen and temperature measurements were collected from each well at three to five minute intervals during well purging. Field parameters with the exception of turbidity were measured in a YSI 600XL multi-meter with flow-through cell. Turbidity measurements were made with a Hach turbidity meter. The field parameter instruments were calibrated prior to use on each day of sampling. Calibration checks were conducted a minimum of two (2) times per day during the sampling activities. After determining that the groundwater elevation stabilization and field parameter stabilization criteria had been achieved according to the stabilization criteria outlined in the SAP, samples were collected for VOC and PCB laboratory analysis. The samples were collected at the same flow rate used during purging. The flow cell was disconnected prior to collecting the sample. The field data sheets are included in Appendix C. A duplicate sample, MW-106BD, was collected from monitoring well, MW-106B. A matrix spike and matrix spike duplicate, MW-106AMS and MW-106AMSD were collected from MW-106A. Other quality control samples included a trip blank, a field blank (FB-1) and an equipment blank (EB-1). All of the samples were stored in a cooler at approximately 4-6 degrees Celcius from the time of sample collection until delivery to the laboratory. Information concerning the sample custody and sample analysis is included in Appendix D. There were no PID readings collected during the April 2012 sampling event. The depth to groundwater measurements were made prior to the purging of the wells and during the well purging. The depths to groundwater measurements are included in the field data record sheets and in Appendix B. An inferred overburden groundwater contour map has been produced for the shallow groundwater aquifer from the April 2012 groundwater elevation data. The inferred overburden groundwater contour map shows generally south-eastward groundwater flow. The map does not show small variations in groundwater flow due to a limited number of monitoring points. The April 2012 overburden groundwater contour map is included in Appendix E.Central Maine Power (225545) 2-2 December 2012

## 2.2 FREE PRODUCT OIL MONITORING Four observation wells (OW-202B, OW-204B, OW-301B and OW-302B), the Phase II VER system recovery well (RW-101), and piezometer UM-1, are not included in the current MOM groundwater SAP. Prior to 2007, these wells were previously monitored monthly, and then quarterly for groundwater elevation and free product thickness as part of a MOM Free Product Oil (FPO) monitoring study. Two observation wells OW-204B and OW-301B and piezometer UM-1 are no longer monitored as they were decommissioned in September 2008. The results of the December 1997 to April 2012 FPO monitoring are shown in Appendix F. In September 2012, measurable oil (0.26 feet) was removed from OW-202B and OW-302B. Between 2006 (decommissioning of the VER system) and 2011, measurable oil was removed from the following wells:

 2011: 0.11 feet OW-202B

 2010: 0.06 feet OW-202B, RW-101

 2009: 0.07 feet OW-202B

 2008: 0.02 feet OW-202B, RW-101

 2007: 0.15 feet OW-202B, RW-101 Prior to that, the last measurable amount of oil removed from RW-101 and OW-202B was 0.11 and 0.24feet, respectively, removed during the VER in 2006. Occasional skim coats of oil were observed at OW302B in 2007 and 2008. Prior to that, OW-302B has been clear of free product, as have the other decommissioned TWA-II wells OW-204B and OW-301B and piezometer UM-1. The VER system was operated on the four observation wells and RW-101 during the following periods: August to October 2001, August and September 2002, August to October 2003, August to September 2004 and August 2006. Oil thickness monitoring conducted at each well during the operation of the VER system showed that a decreasing quantity was recovered: approximately 20 gallons of oil were recovered by the VER in 2001, 7.4 gallons in 2002, 2.5 gallons in 2003, and about 0.3 gallons in 2004 and 2006. The VER process recovered a low volume of oil-product (0.29 gallons) in 2006. The amount of oil removed from the wells using the VER system has decreased steadily over time to minimal amounts. In December 2006, the VER system was decommissioned because the rate of oil recovery using passive recovery was equal to or greater than with the VER system. The passive oil recovery program is continuing on a quarterly basis.Central Maine Power (225545) 3-1 December 2012

# 3. ANALYTICAL RESULTS
The April 2012 groundwater field data records, which record the field parameter measurements and field observations during the groundwater purging as well as other information, are included in Appendix C. Copies of the chain-of-custody forms and other laboratory information are included in Appendix D. The analytical results of the April 2012 MOM groundwater-sampling event are included in Table 1 and the laboratory report is included in Appendix G. The data storage and data management functions are being conducted using GIS/KEY software. This program facilitates data management and data reporting. 1,3,5-trichlorobenzene had not been included in the original scope of work and was not included in the original VOC analyses prior to September 2004. From September 2004 to April 2012, there have been no detections of 1,3,5-trichlorobenzene in groundwater from any of the monitoring well samples collected. This compound will continue to be included in the MOM monitoring in future sample events.


## 3.1 GROUNDWATER RESULTS FROM THE MOM MONITORING PROGRAM Groundwater clean-up standards established in the 1989 ROD include total PCBs at 0.5 ug/L, benzene at 5 ug/L, and 1,4-dichlorobenzene at 27 ug/L. The 2002 ROD Amendment incorporated the Maine MEGs for PCBs of 0.05 ug/L, and chemical-specific ARARs based on USEPA MCLs and MEDEP MEGs for additional VOCs. These are established as groundwater performance standards in the 2003 SOW and are listed in Table 1. The results of the April 2012 water quality monitoring indicate:

 PCBs were not detected at any MOM monitoring wells. The practical quantitation limit (detection limit) for PCBs was lowered from 0.1 to 0.05 ug/L, to be able to detect PCBs down to the Maine MEG of 0.05 ug/L.

 Benzene was not detected at any MOM monitoring wells.

 There were no exceedances of the performance standard for 1,4-dichlorobenzene (27 ug/L) in MOM monitoring wells in April 2012. 1,4-dichlorobenzene was detected below the performance standard in groundwater samples collected from two monitoring well locations; MW-104B, and OW-201B, at concentrations of 1.2, and 1.7 ug/L, respectively.

 1,3,5-trichlorobenzene was not detected in the groundwater in the MOM monitoring wells in April 2012.

 Other target VOCs were detected including 1,2,3-trichlorobenzene in MW-104B; 1,2,4- trichlorobenzene in MW-104B; 1,2-dichlorobenzene in MW-104B, MW-507A and OW-201B; 1,3-dichlorobenzene in MW-104B, MW-507A and OW-201B; and chlorobenzene in MW-104B and OW-201B. Concentrations were well below associated performance standards in all samples.

 The individual VOC results in the groundwater from MW-106A, MW-106B, MW-501, MW-502, MW-503, and MW-508B, were all below the detection limit of 1 ug/L. Quality control results associated with the April 2012 VOC and PCB data were reviewed to determine representativeness and usability. A Tier II validation procedure in which tabulated results are reviewed was used for this assessment. Based on the results of validation, qualifiers, if any, were added to sample concentrations to identify potential bias or false positive results. The initial calibration average relative response factors (RRFs) reported on the continuing calibration summaries were incorrect. The laboratory inadvertently used an earlier unrelated initial calibration curveCentral Maine Power (225545) 3-2 December 2012

MOM 2012 Annual Report 

### when updating the continuing calibration summaries and also when quantitating VOC results for field samples. When notified of the discrepancies, the laboratory reissued corrected continuing calibration forms as well as reprocessed the associated field samples using the correct initial calibration average RRFs. All other quality control parameters were compliant for VOC results; therefore, no sample qualifiers were applied. Trip, field, and method blank results were non-detect for all target VOCs, indicating that there were no interferences from shipping and laboratory processing. Percent recoveries of the surrogate tetrachloro-meta-xylene (TCMX) on both GC columns were below control limits in all samples. In addition, percent recoveries of TCMX as well as decachlorobiphenyl (DCB) in samples OW-201B and MW-104B were below control limits. The non-compliant percent recoveries of TCMX and/or DCB in the samples indicate potential low biases for reported sample results. Positive and non-detected results for PCBs in all samples were qualified as estimated (J/UJ) and may represent potential low biases. Overall, the quality control results for VOC and PCB analyses are compliant and indicate that the associated data are acceptable for monitoring groundwater conditions at the O’Connor Site.Central Maine Power (225545) 3-3 December 2012

MOM 2012 Annual Report 

## 3.2 COMPARISON WITH PREVIOUS MOM RESULTS There have been no PCBs detected in MOM monitoring wells since September 2005 and from 2002- 2005, PCB concentrations ranged from 0.06-0.91 ug/L. There have been no detections of the eight site-specific VOCs above groundwater performance standards since September 2004, and between 2002-2004 the only VOCs to exceed performance standards were 1,2-dichlorobenzene and 1,4-dichlorobenzene. There have been no exceedances of the performance standard for benzene (5 ug/L) in the MOM wells in the last 13 years. There has been a significant improvement in meeting the performance standard for 1,4-dichlorobenzene at the site. Concentrations of 1,4-dichlorobenzene in groundwater have been below the performance standard (27 ug/l) since September 2003, when the performance standard was exceeded at two MOM wells, MW-104B and OW-201B. Prior to December 1997, the concentration of 1,4-dichlorobenzene in OW-201B was in the range of 42-57 ug/L. Between March 1998 and October 2003, the 1,4-dichlorobenzene concentration at MW-201B decreased to 25-36 ug/L, except for 47 ug/L in May 2002. The concentration of 1,4-dichlorobenzene at OW-201B in 2004-2006 ranged from 8-24 ug/L, 8-13 ug/L in 2007-2009, 3 ug/l in both 2010 and 2011, and 1.7 ug/L in 2012. A time series plot showing the historic concentrations of 1,4-dichlorobenzene for several wells is shown in Appendix H and suggests that the concentration is decreasing. The 1,4-dichlorobenzene concentrations at MW-104B were relatively stable at 20-33 ug/L from December 1998 to September 2001 and the range was slightly higher at 28-44 ug/L between September 2002 and September 2003. The concentration of 1,4-dichlorobenzene at MW-104B in 2010 (15 ug/L) was consistent with historic results between 2004-2009 (3-20 ug/L). The concentration of 1,4- dichlorobenzene at MW-104B decreased to 0.8-1.2 ug/L in 2011-2012. A time series plot showing the historic concentrations of 1,4-dichlorobenzene for several wells is shown in Appendix H. The VOC concentrations in groundwater at MW-106A and MW-106B have been relatively consistent over the past seven years. The VOC results for MW-106A have been non-detect since April 2005. From April 2002-2005, the total VOC concentration at MW-106A decreased from 2 ug/L to less than the quantitation limit. The total VOC concentration at MW-106B has decreased from 22.7 ug/L in April 2002 to not detected above the quantitation limit. MW-106B flows under artesian conditions most of the year. MW-106A monitors the overburden aquifer at this location and flows under low artesian conditions during periods of high groundwater. In the area of MW-507A and MW-508B, historically the VOC concentrations have been higher in the overburden groundwater (MW-507A) than in the bedrock groundwater (MW-508B). For the April 2012 sampling event, the total VOC concentration at MW-507A was estimated at 0.7 ug/L and was non-detect at MW-508B. Monitoring well MW-507A is an overburden well located in a bedrock trough and screened in the till/bedrock surface migration pathway where contaminated groundwater from the former TWA source areas flows slowly in a southeasterly direction. These wells were placed at this location to monitor VOC concentrations in the primary, till/bedrock migration pathway (MW-507A) and the secondary bedrock migration pathway (MW-508B).Monitoring wells MW-501, MW-502 and MW-503, are shallow wells located down gradient of MW104B and OW-201B. In April 2012, the concentration of VOCs at MW-501, MW-502 and MW-503 were non-detect, which is consistent with historic results.Central Maine Power (225545) 4-1 December 2012

# 4. CONCLUSIONS AND RECOMMENDATIONS
The April 2012 groundwater-sampling event was conducted in accordance with the current SAP and Quality Assurance Project Plan (QAPP). The results of the April 2012 sampling and a review of historic groundwater data at the O’Connor Site has led to the following conclusions and recommendations:

 There were no exceedances of groundwater performance standards for the eight VOCs analyzed for in the MOM monitoring wells in April 2012. VOCs were detected in three out of nine wells sampled and were well below the groundwater performance standards.

 The concentrations of 1,4-dichlorobenzene in groundwater in the MOM wells are trending downward.

 PCBs were not detected in MOM monitoring wells in April 2012. Following operation of the VER system in the fall of 2006, it was decommissioned because the rate of oil recovery using passive recovery was equal to or greater than with the VER system. The passive oil recovery program will continue on a quarterly basis.Central Maine Power (225545) 5-1 December 2012

### 8260B Analvsis

There were no protocol deviations or observations noted by the organics laboratory staff.
.8082 Analvsis Sample SF2308-6 was used for the matrix spike (MS) and matrix spike duplicate (MSD), as requested by the client. Sample SF2308-l was manually integrated for the Otarget analyte Aroclor 1260. The specific
reason for the manual integration is indicated on the raw data by the manual integration codes (Ml-Mll). These codes are further explained in the attachment following this narrative. Samples SF2308-l, 2, 3, 6, 7, 9, 10, 12, and 13, the method blank, LCS/LCSD, and MS/MSD, WG107474-1 through 5, had low recoveries for the extraction surrogate TCX on one or both channels, which were outside ofthe laboratory established acceptance limits. Since the recoveries for the method required surrogate DCB were within the acceptance limits, no further action was taken. Samples SF2308-4 and 8 had low recoveries for the extraction surrogates TCX and DCB on both channels, which were outside the laboratory established acceptance limits. The client was contacted on 05/0 l/20 12 and infonned the laboratory that the samples did not need to be reextracted.

There were no other protocol deviations or observations noted by the organics laboratory staff. C8rL No. EB76Q.J
