The waste disposal area comprises approximately 13.8 acres. Figure 1, General Location Map illustrates the general location of the landfill on top of a 7.5-minute United States Geologic Survey (USGS) topographic map for the Belews Creek, North Carolina quadrangle (quad). The facility was issued a Permit to Operate by the North Carolina Department of Waste Management (DWM) on May 15, 1985, and a Letter of Closure on December 10, 1991. The landfill is zoned residential/agricultural and is bounded on the east and west by open fields and woodlands. The landfill is bounded on the north by property owned by Waste Management and farther north by Freeman Road, and on the south by an unnamed tributary of Belews Creek. Figure 2, Water Quality Sampling Locations Map illustrates the property boundaries, waste disposal boundaries, monitoring well locations, and surface water sample locations. 1.2 Site Geology and Hydrogeology The Town of Kernersville Landfill is located in the Piedmont Physiographic Province (Piedmont) of North Carolina and is underlain by intrusive granitic rocks of Pennsylvanian -to -Permian age, which are part of the Charlotte Belt Geologic Unit. The uppermost aquifer is unconfined and includes both saprolite and fractured bedrock, which are well-connected. Groundwater at the site has historically been reported flowing generally to the southwest. Joyce Engineering (JOYCE) conducted hydraulic conductivity testing in November 2013 and, using the modified Darcy equation (V=Ki/n), reported the following: • Hydraulic gradient (i) is 0.04 ft/ft; • An effective porosity value (n) of 30 percent was estimated; • Hydraulic conductivity (K) 1.73 ft/day: and • The calculated groundwater flow rate averaged approximately 0.20 ft/day. 1.3 Regulatory Status The Town of Kernersville (Town) is currently monitoring groundwater at the landfill in accordance with criteria set forth in Title 15A Subchapter 13B .0500 of the North Carolina Solid Waste Management Rules for municipal solid waste landfills (MSWLF) closed prior to October 9, 1993. Samples are analyzed for all constituents listed in 40 CFR Part 258, Appendix I Constituents for Detection Monitoring ("Appendix I") and compared to the North Carolina Groundwater Quality Standards as listed in 15A NCAC 2L (the "2L Standards"), or, when a 2L Standard is not established, the Solid Waste Section's Groundwater Protection Standards (GWPs) or Interim Maximum Allowable Concentrations (IMACs). Based on the presence of targeted Appendix I constituents detected at concentrations above the referenced standards that could potentially be crossing the facility boundary, the North Carolina Department of Environment and Natural Resources (NCDENR), Solid Waste Section January 2020 Water Quality Monitoring Report Town of Kernersville Closed Landfill, Permit 34-04 WR Project Number 06140180.33 March 2020 Page 1 of 7 ■r .. Our People. Your Success. (Section) requested that the Town submit a Groundwater Assessment Plan to evaluate site conditions as they relate to groundwater quality. JOYCE submitted a Groundwater Assessment Report to the Section on May 13, 2013, and concluded that, based on site hydrogeology, it would be very unlikely that the site impacts at concentrations above their respective standards would cross the property boundaries. In a July 16, 2013 response to information presented in the Groundwater Assessment Report, the Section determined that, despite the conclusions presented in JOYCE's Groundwater Assessment Report, the detection of volatile organic compounds (VOCs) at concentrations that exceeded the referenced standards beyond the compliance boundary of the site constituted a violation of Section regulations. JOYCE submitted a Corrective Action Plan (CAP) on behalf of the Town in July 2014, which the Section approved on November 4, 2014. Note that the NCDENR is now doing business as the North Carolina Department of Environmental Quality (NCDEQ). 2.0 FACILITY MONITORING PROGRAM 2.1 Groundwater Monitoring Program The current groundwater quality monitoring network consists of six monitoring wells, including one upgradient (background) well and five downgradient (compliance) wells. Monitoring well locations are illustrated on Figure 2. Monitoring well MW-6 currently serves as the background well for the facility. Former background monitoring well MW-1 was replaced (by monitoring well MW-6) due to slow recharge in the well, low well volumes, or being dry during sampling events. Downgradient monitoring wells MW-2, MW-3S, MW-3D, MW-4, and MW-5 are monitored for the Appendix I list of constituents as part of the compliance network for the facility. Monitoring well MW-1 is currently monitored for water levels only. Well construction parameters are presented in Table 1, Monitoring Well Construction Details. As a condition of the aforementioned CAP, monitoring wells MW-2, MW-3S, MW-3D, MW-4 and MW-6 are also monitored for the following Monitored Natural Attenuation (MNA) constituents: • Nitrate, sulfate, chloride, sulfide, alkalinity; • Total organic carbon (TOC); • Methane, ethane, and ethane; • Dissolved Hydrogen; • Ferrous Iron; • Biological oxygen demand (BOD); and • Chemical oxygen demand (COD). Groundwater samples collected semiannually are analyzed for the Appendix I list of constituents and for the above -referenced MNA parameters. Sample analyses are then compared to the 2L Standards or IMACs or GWPs, where appropriate. 2.2 Surface Water Monitoring Program Surface water at the landfill is monitored semi-annually in conjunction with the groundwater sampling events. Samples are collected from three surface water monitoring points (designated SW-1, SW-2, and SW-3). Surface water sample locations are also illustrated on Figure 2. January 2020 Water Quality Monitoring Report Town of Kernersville Closed Landfill, Permit 34-04 WR Project Number 06140180.33 March 2020 Page 2 of 7 ■r .. Our People. Your Success. These surface water monitoring points are summarized below, along with their current monitoring program status. Surface Water Designation SW-1 SW-2 SW-3 Classification Upstream/Compliance Compliance Compliance Surface water samples are collected and analyzed for the Appendix I list of constituents during both semiannual monitoring events. Analytical results are compared to the Classifications and Water Quality Standards Applicable to Surface Waters of NC as listed in 15A NCAC 2B (213 Standards). 3.0 GROUNDWATER AND SURFACE WATER SAMPLING EVENT 3.1 Field Services On January 8, 2020, WithersRavenel (WR) personnel mobilized to the facility to purge and sample monitoring wells MW-1, MW-2, MW-3S, MW-3D, MW-4, MW-5, and MW-6 and sample surface water sample locations SW-1, SW-2, and SW-3. Prior to purging each well, the depth to the static water level was measured with an electronic water level indicator accurate to 0.01-foot. Due to the lack of water encountered within the well, monitoring well MW-1 was measured for static water level only. Table 2, Groundwater Surface Elevations presents groundwater surface elevations calculated from static water levels recorded by WR personnel compared to top -of -well casing elevations reported by JOYCE in their 2015 reports. For comparison purposes, the most recent sampling event (July 2019) data are illustrated on some of the figures. Figure 3A, Potentiometric Map (January 2020) illustrates estimated groundwater flow across the landfill site based on the reported groundwater surface elevations during the January 2020 sampling event. Figure 313, Potentiometric Map (July 2019) illustrates estimated groundwater flow across the landfill site based on the reported groundwater surface elevations during the July 2019 sampling event. As shown on these figures and in recent sampling events, groundwater appears to be flowing in a southwesterly direction towards an unnamed tributary of East Belews Creek. Table 3, Historical Groundwater Elevations presents groundwater surface elevations reported by JOYCE between 2009 and 2015, and by WR between 2016 and 2019. The monitoring wells were purged and sampled using either disposable bailers or submersible pump. Field parameters, including temperature, pH, specific conductivity, dissolved oxygen, oxidation-reduction potential, and turbidity, were recorded in the site -specific log book prior to purging, after each purge volume, and during sampling. Groundwater samples from each monitoring well were collected directly from a submersible pump into laboratory -prepared and -provided containers or decanted from disposable bailers into the containers immediately after purging. Samples were then placed into laboratory - provided coolers, chilled on ice to approximately 4°C, and delivered to a State of North Carolina - January 2020 Water Quality Monitoring Report WR Project Number 06140180.33 Town of Kernersville Closed Landfill, Permit 34-04 March 2020 Page 3 of 7 ■r .. Our People. Your Success. certified laboratory (Research & Analytical Laboratories) under standard Chain -of -Custody (COC) protocol. Field data logs are provided in the Appendix to this report. Surface water samples were collected either directly into laboratory -provided, non -preserved sample containers, or by decanting the sample from a non -preserved 1-Liter amber glass container into the appropriate containers. In both methods, samples were collected with the container opening facing into the current flow. When used, care was taken to not overflow the preserved sample containers (which could lead to preservative loss) and avoid sample -induced turbidity. Samples were collected initially from the downstream sample location (SW-2), and in sequence upstream, SW-3 and then SW-1 samples were collected (Figure 2). After sample collection, the samples were placed in a laboratory -provided cooler, chilled on ice to approximately 4°C, and submitted to Research & Analytical Laboratories under standard COC protocol. 3.2 Quality Control One Field Blank was collected by WR personnel as part of the January 2020 sampling event. Also, a Trip Blank was prepared by the laboratory to accompany the volatile sampling containers during shipment to and from the laboratory. The Field Blank was analyzed for the Appendix list of constituents only, while the Trip Blank was analyzed for VOCs only. 4.0 ANALYTICAL RESULTS 4.1 Groundwater Groundwater samples were analyzed for the Appendix I list and the modified list of MNA constituents and compared to the respective 2L Standards or GWPs where appropriate. As shown on Table 4, Groundwater Analytical Results, the following organic and/or inorganic constituents were detected in groundwater samples during the January 2020 sampling event. All concentrations are reported in micrograms per liter (µg/L). Concentrations detected above the 2L Standard or GWPs are illustrated in bold font.

Your Success. 4.2 Surface Water Surface water samples were analyzed for the Appendix I list only. No analytes were detected at concentrations above the 2B Standards in surface water samples collected during the January 2020 sampling event. The results were consistent with historical data. Surface water data can be found in Table 5, Surface Water Analytical Results. The results, as reported by the laboratory, historical surface water data, the laboratory quality/assurance/quality control information, and the chain -of -custody records are included in the Appendix. 5.0 MONITORED NATURAL ATTENUATION (MNA) EVALUATION 5.1 MNA Parameters According to previous reports, in accordance with the facility CAP, MNA baseline sampling was initiated during the November 2014 sampling event and finished during the November 2015 sampling event. During those events, the full list of MNA parameters (shown below) were measured in samples collected from monitoring wells MW-2, MW-3S, MW-3D, and MW-4. MNA field (geochemical) parameters included: • Temperature; • pH; • Specific conductance; • Oxidation-reduction potential (ORP); • Turbidity; and • Dissolved oxygen. Laboratory parameters included: • Biological Oxygen Demand (BOD); • Chemical Oxygen Demand (COD); • Dissolved hydrogen; • Nitrate; • Sulfate: • Chloride; • Alkalinity; • Sulfide; • Total Organic Carbon (TOC); • Ethane, ethene, and methane; and • Volatile fatty acids. As shown on Table 6, Summary of MNA Constituents, WR sampled for the full list of MNA parameters during the January 2020 sampling event. Laboratory reports and field data forms are included in the Appendix. 5.2 Biodegradation Screening Matrix The MNA parameter data were evaluated in general accordance with the weighted system presented in Table 2.3, Biodegradation Screening Matrix (Matrix) of the United States Environmental Protection Agency's (USEPA's) Technical Protocol for Evaluation of Natural Attenuation of Chlorinated Solvents in Groundwater (Manual), to determine whether the conditions are conducive to, or whether there is evidence of, anaerobic degradation of the chlorinated hydrocarbons. According to information presented in the Manual, January 2020 Water Quality Monitoring Report Town of Kernersville Closed Landfill, Permit 34-04 WR Project Number 06140180.33 March 2020 Page 5 of 7 ■r .. Our People. Your Success. • A score less than 5 indicates that there is "inadequate evidence" for anaerobic natural attenuation; • A score of 6 to 14 indicates that there is "limited evidence" for anaerobic natural attenuation; • A score of 15 to 19 indicates that there is "adequate evidence" for anaerobic natural attenuation; and • A score of 20 or more indicates that there is "strong evidence" that anaerobic natural attenuation is occurring. The MNA evaluation was performed based on the results from the January 2020 sampling event for downgradient wells located within the contaminant plume and compared, where appropriate, to samples collected from the background well (MW-6). Because it is unclear whether some of the target analytes are naturally -occurring or daughter products resulting from natural attenuation, the scores have been calculated with and without the daughter product points. The site -specific Matrix for this sampling event is presented in Table 6 of Appendixll. As shown, the score for this event was 26 (characterized as "strong evidence of natural attenuation.") 6.0 FINDINGS Target analytes detected above their respective 2L Standards and/or GWPs in groundwater samples collected during the January 2020 sampling event appear to generally be consistent with previous events. In addition, there were no target analytes detected in the surface water samples at concentrations above their respective 2B Standards. The Town of Kernersville Landfill will continue to monitor groundwater in accordance with the approved CAP. The next semiannual sampling event is tentatively scheduled for July 2020.
