Closed Feltonsville Landfill Facility Permit No. 9203- MSWLF-1980 Semi-Annual Sampling Report (April 2017 Sampling Event) Wake County Report Prepared June 2017 5400 Glenwood Ave, Suite 400 Raleigh, North Carolina 27612 tel: 919 325-3500 fax: 919 781-5730 June 1, 2017 Ms. Jaclynne Drummond North Carolina Department of Environmental Quality Division of Waste Management Solid Waste Section 2090 U.S. 70 Highway Swannanoa, North Carolina 28778 Subject: April 2017 Semi-Annual Groundwater Sampling Report Closed Feltonsville Landfill - Wake County Facility Permit No. 9203-MSWLF-1980 Dear Ms. Drummond: CDM Smith Inc., on behalf of Wake County, is submitting an electronic copy of the April 2017 semi-annual sampling event report. This letter report presents the results of the semi-annual sampling event that was recently completed at the Closed Feltonsville Landfill and constitutes the first semi- annual sampling event for 2017. The current groundwater monitoring network consists of the following wells: MW-2, -4, -6, -8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18, -19, -20, -21, -22, -23, -24, -25, -26, -27, -28, and -29 as well as surface water sampling locations SW-1, -2, and -3. Monitoring wells MW-2, -6, -8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18, -19, -20, -28, and -29 monitor the closed Feltonsville Landfill. The remaining wells (i.e. MW-4, -21, -22, -23, -24, -25, -26, and -27) monitor the old cells located in the back of the property. Field activities, sampling results for all wells and surface water locations, an evaluation of the groundwater corrective action effectiveness, and recommendations are discussed below. Field Activities Groundwater and surface water samples from the Closed Feltonsville Landfill were collected on April 27- 28, 2017. Monitoring well and surface water sample locations are shown on Figure 1. Construction details for each monitoring well are summarized in Table 1. Samples were collected from the monitoring wells by use of a peristaltic pump or disposable, laboratory decontaminated bailers. Groundwater elevations were measured at each well on April 26, 2017, using an electronic water level indicator with an accuracy of 0.01 feet and are presented in Table 1. These groundwater elevations were used to construct potentiometric contours for this sampling event and are shown on Figure 1. The groundwater elevations and potentiometric contours were also used to estimate groundwater velocities at each well as presented in Table 2. Ms. Jaclynne Drummond June 1, 2017 Page 2 After depth to groundwater was determined, three well volumes of water were removed from each well prior to sampling to provide fresh formation water within the well water column. Each well volume and surface water sample was measured in the field for pH, conductivity, temperature, turbidity, dissolved oxygen, and oxidation-reduction potential using a YSI-556 multi-parameter water quality meter and a HANNA HI 98703 turbidity meter. Wells that had elevated turbidity were allowed to stabilize prior to sample collection. The water quality parameters at the time of sampling are provided in Table 3. Sampling Results Groundwater and surface water samples were analyzed by Shealy Environmental Services, Inc. located in West Columbia, South Carolina, for the North Carolina Appendix I volatile organic compounds (VOCs) plus dichlorodifluoromethane and Appendix I metals plus mercury. Additional samples were collected from select monitoring wells to evaluate natural attenuation and the effectiveness of the corrective action. Results of the additional sampling and an evaluation of natural attenuation are discussed in the next section of this report. In accordance with North Carolina Department of Environmental Quality - Solid Waste Section (SWS) guidelines the analytical results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at or below SWS Limits (SWSLs). All monitoring wells and surface water locations for the closed Feltonsville Landfill had detections of analytes above the MDL with a majority of the detections below SWSLs. These detections were qualified as estimated or “J” flags. “B” flags, which indicate an analyte was detected in the method blank, were also reported. The following list indicates the analytes detected above the MDL at each sampling location. No “J” flag detections are provided. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater Quality Standard, Groundwater Protection Standard, or the 15A NCAC 02B Surface Water Quality Standard for Class C Waters. A complete summary of all detected and estimated concentrations for the March 2011 through the April 2017 sampling events, as well as historical detections of herbicides, pesticides, and polychlorinated biphenyls, is provided in Table 4. Laboratory data reports are provided in Appendix A.

The “J” flag constituents above the standards along with their location are listed below: Antimony: MW-14 Cadmium: SW-3 Cobalt: MW-8, -11, -13, -16, -18, -19, -22, -23, -24, -28, and -29 Lead: SW-2 and -3 Ms. Jaclynne Drummond June 1, 2017 Page 6 Vanadium: MW-2, -4, -6, -8, -9, -10, -11, -13, -14, -15, -17, -18, -19, -20, -21, -22, -23, -24, -25, -26, -27, -28, and -29 Equipment and trip blanks were analyzed for quality control. A duplicate sample was also collected for quality control. The duplicate sample, labeled DUP, was collected from MW-12 and had similar concentrations to the MW-12 sample, with the exception of estimated detections of copper and mercury in the parent sample. Additionally, an estimated concentration of dichlorofluoromethane was detected in the duplicate sample, but not the parent sample. The equipment blank had “J” flag detections of acetone and 2-butatone below their respective NC 2L Standard. Vanadium was detected as an estimated concentration in the equipment blank above its Groundwater Protection Standard. No VOCs were detected in the trip blank above the MDLs. Table 5 presents a summary of all parameters detected during the April 2017 sampling event that exceeded the NC 2L or Groundwater Protection Standards. Monitored Natural Attenuation Sampling Additional groundwater samples were collected from the background well, MW-2, and downgradient monitoring wells MW-8, -9, -10, -12, -13, and -14. The samples were analyzed for alkalinity, biochemical oxygen demand, chemical oxygen demand, carbon dioxide, chloride, dissolved hydrogen, methane, ethane, ethene, volatile fatty acids (i.e. acetic, butyric, lactic, propionic, and pyruvic), nitrate, sulfate, sulfide, and total organic carbon. Ferrous iron was also analyzed using a HACH test field kit due to the short hold time (i.e. 15 minutes). These additional samples were collected to monitor for natural attenuation as part of the approved corrective action program as required by SWS guidelines. Additional samples were also collected from wells MW-19 and -29, which are located downgradient of the injection area, in order to monitor the effectiveness of the injection. Sampling results are provided in Table 6 and trend figures of total detected VOCs for select wells are presented on Figures 2-10. Corrective Action via In situ Bioremediation Injection In accordance with the Corrective Action Plan that was approved by the SWS in a letter dated December 1, 2011, two in situ bioremediation injections have been completed. Phase I consisted of injecting sodium lactate into 5 injection wells upgradient of monitoring wells MW-8, -9, and -10 on June 18-21, 2012. A total of 1,268 gallons of a 10% sodium lactate solution were injected resulting in each well receiving approximately 254 gallons of the sodium lactate solution. Phase I post-injection samples were collected 1, 2, and 5 months after injection. During each sampling event, samples from MW-8, -9, -10, -19, and -29 were analyzed for the following field measurements: pH, temperature, oxidation-reduction potential, dissolved oxygen, conductivity, turbidity, nitrate, sulfate, ferrous iron, carbon dioxide, and alkalinity along with laboratory analyses of chlorides, chemical oxygen demand, VOCs, dissolved gases (i.e. methane, ethane, and ethene), sodium, and total dissolved solids. Volatile fatty acids were also collected during the 1 month post-injection sampling event. Ms. Jaclynne Drummond June 1, 2017 Page 7 Additionally, samples were collected from MW-8, -9, and -10 and analyzed for bacterial population size and functional gene presence during the baseline and 5 month post-injection sampling events. Analytical results for each sampling event are summarized in Tables 4 and 6. Analytical results post-sodium lactate injection for MW-8, -9, and -10 indicated that bioremediation was occurring with no VOCs detected above NC 2L standards in MW-8 or -10, with the exception of 1,1- dichloroethane detected in samples collected from MW-10 in July 2012. MW-9 had detections of 1,1- dichloroethane, tetrachloroethene, trichloroethene, and vinyl chloride above NC 2L standards, but contaminant concentrations were decreasing. DNA analyses revealed healthy populations of bacteria (Dehalococcoides sp) in MW-9 and -10 that continued to reduce contaminant concentrations. Bacterial populations in MW-8 decreased as a result of little to no VOCs being detected during the post-injection sampling. The Phase I injection of sodium lactate successfully caused degradation of trichloroethene and tetrachloroethene to daughter products using enhanced anaerobic bioremediation in the injection area. Although the Phase I injection reduced contaminant concentrations, a second injection was needed to supply a longer lasting source of electron donors. Biodegradation can be sustained for as long as sufficient concentrations of substrate remain in the groundwater. For this reason, emulsified vegetable oil was utilized in the Phase 2 injection as it is a slow-release compound, and therefore should release organic carbon into the groundwater for three to five years, depending on site conditions. During the Phase 2 injection, a 10% emulsified vegetable oil solution was injected into the injection wells on March 25-27, 2013. Injection at each well consisted of approximately 220 gallons of water containing approximately 22 gallons of the emulsified vegetable oil product. The emulsified vegetable oil product consisted of 60% emulsified vegetable oil and 4% sodium lactate by weight, which resulted in a total injection volume of 1,100 gallons of water and 110 gallons of emulsified vegetable oil product. Post-injection samples were collected 1, 4, 7, 10, and 12 months after injection. The April 2014 monitoring event concluded the post-injection monitoring. Analyses for each sampling event were similar to the Phase I events except that a DNA analyses to determine bacterial population size and functional gene presence was only done during the April 2014 sampling event. No VOCs have been detected above the standards in MW-8 since the November 2011 semi-annual sampling event. Benzene and 1,1-dichloroethane were detected above their respective NC 2L Standards in MW-9 during the April 2017 sampling event. The concentration of 1,1,-dichloroethane in MW-9 shows a decreasing trend. Benzene was detected slightly above the standard (1 part per billion (ppb)) at 1.1 ppb. Historically, benzene has been detected as a “J” flag detection below the standards with the exception of the May 2015 sampling event were it was detected at 1.1 ppb. Ms. Jaclynne Drummond June 1, 2017 Page 8 MW-10 samples had concentrations of benzene, 1,1-dichloroethane, and an estimated concentration of vinyl chloride above their respective NC 2L Standards. 1,1-Dichloroethane and vinyl chloride show a decreasing trend. Concentrations of benzene have historically fluctuated at MW-10. No VOCs were detected in samples collected from bedrock monitoring well MW-19 during the April 2017 sampling event with the exception of an estimated concentration of trans-1,2-dichloroethene below the NC 2L Standard. Historically, VOCs have never been detected above the standards in monitoring well MW-19. MW-29, located at the compliance boundary, has not had any chlorinated ethenes detected above NC 2L Standards since November 2012. No VOCs were detected in samples collected from MW-29 during the April 2017 sampling event with the exception of an estimated concentration of acetone below its NC 2L Standard. Concentrations of 1,1-dichloroethane have decreased following the injection events. 1,1- Dichloroethane has been detected below the NC 2L Standard since the January 2014 post-injection sampling event with the exception of the October 2014 semi-annual sampling event (7.2 ppb) when it was detected slightly above the NC 2L Standard (6 ppb). Dechlorination of chlorinated ethenes from tetrachloroethene to ethene is ongoing. Chlorinated ethene concentrations in MW-9 and -10 remain below the NC 2L Standards. The geochemical data indicates favorable conditions for reductive dechlorination based on samples collected from MW-9 and -10 during the April 2017 monitoring event. Subsequent monitoring events will be evaluated to identify any trends. Recommendations Wake County will continue with the semi-annual assessment monitoring program. All wells will continue to be sampled for Appendix I VOCs plus dichlorodifluoromethane and Appendix I metals plus mercury. Samples collected from MW-2, -8, -9, -10, -12, -13, and -14 will also be analyzed for natural attenuation parameters. The next semi-annual sampling event will be completed in the fall of 2017.

The sample receiving date is documented in the header information associated with each sample. All results listed in this report relate only to the samples that are contained within this report. Sample receipt, sample analysis, and data review have been performed in accordance with the most current approved NELAC standards, the Shealy Environmental Services, Inc. ("Shealy") Quality Assurance Management Plan (QAMP), standard operating procedures (SOPs), and Shealy policies. Any exceptions to the NELAC standards, the QAMP, SOPs or policies are qualified on the results page or discussed below.

VOC 8260B The continuing calibration verification (CCV) associated with samples SD28007-009 (MW-20), SD28007-010 (MW-24), SD28007-011 (MW-25), SD28007-012 (MW-28), SD28007-013 (MW-29), SD28007-014 (DUP),for analytes: DCDFM, Acetone and Acrylonitrile recovered above the upper control limit. The samples associated with this CCV were non-detect for the affected analytes; therefore, the data has been reported except for sample SD28010-003 (MW-9) for Acetone and SD28020-006 (MW-16) for DCDFM. Both of these samples were re-analyzed for affected target analytes and reported. Nitrate Sample SD28007-005 (MW-12) was diluted due to the nature of the sample matrix (high chloride).
