This letter report presents the results of the semi-annual sampling event that was recently completed at the Closed Feltonsville Landfill (Site) and constitutes the second semi-annual sampling event for 2022. 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, and 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 Site. 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 samples were collected from the Site on September 27-29, 2022. All surface water sampling locations were dry and were not sampled. 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 bailer. Groundwater elevations were measured at each well prior to sampling on September 27, 2022, 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. 0 WATER + ENVIRONMENT+ TRANSPORTATION+ ENERGY + FACILITIES smith Ms. Jaclynne Drummond January 3, 2023 Page 2 After depth to groundwater was determined, a minimum of 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 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 (i.e., greater than 10 Nephelometric Turbidity Units (NTUs)) were allowed to stabilize prior to sample collection. The water quality parameters at the time of sampling are provided in Table 3. Alternate Source Demonstration Analytical data was collected from the Site's background monitoring well, MW-2, on a quarterly basis from January 2018 to April 2020 to determine if the metals exceeding the NCAC 02L .0202 (NC 2L) Groundwater Standards or Interim Maximum Allowable Concentrations (IMACs) were due to naturally occurring background concentrations or a release from the landfill. Based on statistical analysis, historical detections of metals above their respective NC 2L Groundwater Standards or IMACs were determined to be indicative of naturally occurring background concentrations instead of a release from the landfill. Future metal detections will be evaluated, and an Alternate Source Demonstration will be submitted to the North Carolina Department of Environmental Quality's Solid Waste Section (SWS) if there are constant detections of metals exceeding their NC 2L Groundwater Standards. Sampling Results Groundwater and surface water samples were analyzed by Pace Analytical Services, LLC, 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 a letter dated May 29, 2018, the SWS stated that all groundwater and surface water samples collected from landfills be analyzed for 1,4-dioxane after July 1, 2018. On June 26, 2019, the SWS approved the removal of 1,4-dioxane from the sampling program for all monitoring wells and surface water locations, with the exceptions of MW-6, -9, -10, -11, -12, -13, -14, -15, -17, -18, -24, -25, -26, -27, and -29, because of two non -detect events (November 2018 and April 2019). Samples were collected from the monitoring wells requiring the 1,4-dioxane analysis during the September 2022 semi-annual sampling event and analyzed for 1,4-dioxane. Sample results are provided below. The analytical results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at or below the laboratory limit of quantitation (LOQ). All monitoring wells for the Site had detections of analytes above the MDL but below the LOQ that were qualified as estimated or "J" flags. co smith Ms. Jaclynne Drummond January 3, 2023 Page 3 In samples collected from MW-22 and -25, detections of barium had a "D" flag, indicating that the samples were analyzed at a dilution greater than one. MW-25 also had a detection of dissolved barium with a "D" flag. In samples collected from MW-2, a detection of chloride also had a "D" flag. In samples collected from MW-10 and -14, detections of nitrate also had "D" flags. Additionally, samples collected from MW-9 had a detection of methane with a "D" flag. MW-9 also had a biochemical oxygen demand detection with a "7" flag, indicating that the seed correction factor was out of range. In samples collected from MW-16, a detection of dichlorodifluoromethane had an "H" flag, indicating that the sample was analyzed outside of its hold time. A detection of tetrahydrofuran in samples collected from MW-26 and a detection of 1,1-dichloroethene in samples collected from MW-27 also had "H" flags. Additionally, in samples collected from MW-2, -8, -9, -10, -14, and -19 detections of nitrate had "H" flags. In samples collected from MW-8, -10, -12, -13, -14, -19, and -29 detections of methane had a "B" flag, indicating that the analyte was detected in the associated method blank. In samples collected from MW-10, -14, nitrate also had a "B" flag and an "L" flag. An "L" flag indicates that there was a laboratory control spike/laboratory control spike duplicate failure. The following list indicates the analytes detected above the LOQ at each sampling location. No "J" flag detections are provided. Underlined groundwater analytes exceeded the NC 2L Groundwater Standard or IMAC. A complete summary of all detected and estimated concentrations for the April 2012 through the September 2022 sampling events is provided in Table 4.

A duplicate sample was also collected for quality control. A detection of toluene was detected below its NC 2L Groundwater Standard in the equipment blank. The trip blanks had no detections above the MDLs. The duplicate sample, labeled DUP, was collected from MW-20, and had similar concentrations as MW-20 with the exception of estimated detections of lead and zinc below their respective NC 2L Groundwater Standards in the parent sample. The parent sample also had a detection of vanadium below its NC 2L Groundwater Standard. Table 5 presents a summary of all parameters detected during the September 2022 sampling event that exceeded the NC 2L Groundwater Standards or IMACs Pesticides, herbicides, and polychlorinated biphenyls have not been sampled for since April 2011 and the last detections above the standards were in May 2010. Historical data is available upon request. Additional metals samples were collected from monitoring wells MW-12, -18, -24, -25, and -29 during the September 2022 sampling event for the laboratory to filter and analyze due to elevated turbidity 0 smith Ms. Jaclynne Drummond January 3, 2023 Page 7 (i.e., greater than 10 NTUs) at the time samples were collected. Total metals that exceeded the NC 2L Groundwater Standards in these wells were analyzed for dissolved metals to determine if turbidity was a contributing factor to total reported metals. Below is a summary of the dissolved metals exceedances. Wells with a "' qualifier had a "J" flag detection for that analyte. Cobalt: MW-18, -24, -25*, and -29 Barium MW-25 Dissolved metal sample results are provided in Table 4 and the laboratory data report is provided in Appendix A. Based on qualitative and quantitative evaluation of current and historic groundwater sampling data, the NC 2L Groundwater Standard metal exceedances from the September 2022 sampling event were determined to be indicative of naturally occurring background concentrations as opposed to a release from the landfill. 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, biological oxygen demand, chemical oxygen demand (COD), carbon dioxide, chloride, dissolved hydrogen, dissolved gasses (i.e., 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, to monitor the effectiveness of the injection. Samples collected from MW-8, -9, -10, -19, and -29 were also analyzed for sodium and TDS. 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, two in situ bioremediation injections have been completed. Phase I consisted of injecting sodium lactate into five injection wells upgradient of monitoring wells MW-8, -9, and -10. A total of 1,268 gallons of a 10 percent 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, COD, VOCs, dissolved gases, sodium, and TDS. Volatile fatty acids were also collected during the 1-month post -injection sampling event. Additionally, samples were collected from MW-8, -9, and -10 and co smith Ms. Jaclynne Drummond January 3, 2023 Page 8 analyzed for bacterial population size and functional gene presence during the baseline and 5-month post -injection sampling events. Analytical results for the November 2011 through April 2022 sampling events 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 Groundwater Standards in MW-8 or -10, except for 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 Groundwater Standards, but contaminant concentrations were decreasing. DNA analyses revealed healthy populations of bacteria (Deholococcoides 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 percent emulsified vegetable oil solution was injected into the injection wells. 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 percent emulsified vegetable oil and 4 percent 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 DNA analyses to determine bacterial population size and functional gene presence were 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, except for the April 2019 sampling event. Samples collected from MW-8 in April 2019 had detections of 1,1-dichloroethane and tetrachloroethene above their respective NC 2L Groundwater Standards. In samples collected from MW-9, benzene was detected slightly above its standard during the September 2022 event. Benzene has been detected above its standard since May 2015, except for the November 2015, April 2016, October 2021, and April 2022 sampling events. Benzene was either reported as an estimated concentration below the standard or was not detected from September 1994 0 smith Ms. Jaclynne Drummond January 3, 2023 Page 9 to October 2014. 1,1-Dichloroethane has historically been detected above the standard, except during the September 2019 and October 2020 sampling events. 1,1-Dichloroethane concentrations have also shown a recent decline and have been detected under the NC 2L Groundwater Standard since the October 2021 sampling event. 1,4-Dioxane was detected above the NC 2L Groundwater Standard (3 parts per billion (ppb)) at 4.7 ppb and has been detected at similar concentrations above the standard since being added to the sampling program in the fall of 2018. Total VOC concentrations have fluctuated since the March 2013 injection. In MW-10, benzene, 1,1-dichloroethane, 1,4-dioxane, and vinyl chloride were detected above their respective NC 2L Groundwater Standards. The concentration of 1,1-dichloroethane has fluctuated but shows a decreasing trend since the May 2015 sampling event. Concentrations of benzene have historically fluctuated at MW-10 but have been showing a decreasing trend since the October 2020 sampling. As expected, the concentration of vinyl chloride has fluctuated following the Phase 2 injection and has shown a decreasing trend since the May 2015 semi-annual sampling event. No VOCs were detected above the MDLs in samples collected from MW-19 during the September 2022 sampling event. Historically, VOCs have never been detected above the standards in monitoring well M W-19. MW-29, located at the compliance boundary, has not had any chlorinated ethenes detected above the NC 2L Groundwater Standards since November 2012. Chloroethane and 1,1-dichloroethane were detected in samples collected from MW-29 during the September 2022 sampling event below their respective NC 2L Groundwater Standards. Concentrations of 1,1-dichloroethane have decreased following the injection events. 1,1-Dichloroethane has been detected below the NC 2L Groundwater Standard since the January 2014 post -injection sampling event except for the October 2014 semi-annual sampling event (7.2 ppb) when it was detected slightly above the NC 2L Groundwater Standard (6 ppb). Dechlorination of chlorinated ethenes from tetra chloroethene to ethene is ongoing. Chlorinated ethene concentrations in MW-9 and -10 remain below the NC 2L Groundwater Standards. The geochemical data will continue to be evaluated to determine if conditions for reductive dechlorination remain present. 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. The concentration of 1,4-dioxane will continue to be monitored in MW-6, -9, -10, -11, -12, -13, -14, -15, -17, -18, -24, -25, -26, -27, and -29. Samples collected from MW-2, -8, -9, -10, -12, -13, -14, -19, and -29 will also be analyzed for natural attenuation parameters.
