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), Solid Waste Section (Section) 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 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 Section's Groundwater Protection Standards (GWPs) or Interim Maximum Allowable Concentrations (IMACs). January 2023 Water Quality Monitoring Report Town of Kernersville Closed Landfill, Permit 34-04 WR Project Number 06140180.62 February 2023 Page 1 of 8 ■■ WithersRavenel .. Our People. Your Success. 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 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). On April 11, 2022 in response to the Corrective Action Evaluation Report dated March 19, 2022, the Town has requested to continue current monitoring procedures of Monitoring Natural Attenuation and Phytoremediation without modification. The Section approved the report with the following conditions: 1. Replacing or repairing the consistently dry monitoring well MW-1 before the end of 2022, 2. Including a new surface water sample location to the July 2022 monitoring event between existing surface water sample locations SW-2 and SW-3 in relation to protection of human health and the environment, and 3. Including the analysis of 1,4-Dioxane for the groundwater monitoring well and surface water samples in future semiannual monitoring events. 1.4 Monitoring Well Construction Activities On July 20, 2022, WR mobilized to the site and installed a monitoring well, MW-1R, to replace the consistently dry monitoring well MW-1. WR advanced on boring to construct a new Type II groundwater monitoring well on site to the northeast of the waste disposal area, MW-1R, to a depth of 40 feet below ground surface (bgs), and the PVC casing was set at 30 feet bgs. Soil cuttings from the boring were field screened with a photoionization detector (PID) for the purpose of detecting volatile organic compounds (VOCs). Monitoring well construction information is available in Table 1. A map showing monitoring well locations is provided as Figure 2. The monitoring well was completed with a stick-up cover and was developed to remove sediment. Boring log, photos, and monitoring well construction information are included in Appendix II of July 2022 Water Quality Monitoring Report, Town of Kernersville Landfill Permit 34- 04, September 12, 2022.

Your Success. 2.0 FACILITY MONITORING PROGRAM 2.1 Groundwater Monitoring Program The current groundwater quality monitoring network consists of six monitoring wells, including two upgradient (background) wells and five downgradient (compliance) wells. Monitoring well locations are illustrated on Figure 2. Monitoring well MW-6 currently serves as a background well for the facility. Former background monitoring well MW-1 was replaced in July 2022 by monitoring well MW-1R due to slow recharge in the well, low well volumes, or being dry during sampling events. Downgradient monitoring wells MW-2R, MW-3S, MW-3D, MW-4, and MW- 5R are monitored for the Appendix I list of constituents as part of the compliance network for the facility. Well construction parameters are presented in Table 1, Monitoring Well Construction Details. As a condition of the aforementioned CAP, monitoring wells MW-1R, MW-2R, MW-3S, MW- 3D, MW-4, MW-5R, and MW-6 are also periodically monitored for the following Monitored Natural Attenuation (MNA) constituents: • Nitrate, sulfate, chloride, sulfide, alkalinity, and • Total organic carbon (TOC) Groundwater samples collected semiannually are analyzed for the Appendix I list of constituents, the above -referenced MNA parameters, and 1,4-Dioxane. 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 four surface water monitoring points (designated SW-1, SW-2, SW-3, and SW-4). Surface water sample locations are also illustrated on Figure 2. These surface water monitoring points are summarized below, along with their current monitoring program status. Surface Water Desienation SW-1 SW-2 SW-3 SW-4 Classification Upstream/Compliance Compliance Compliance Compliance Surface water samples are collected and analyzed for 1,4-Dioxane and 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).

Your Success. 3.0 GROUNDWATER AND SURFACE WATER SAMPLING EVENT 3.1 Field Services On July 28, 2022, WithersRavenel (WR) personnel mobilized to the facility to purge and sample monitoring wells MW-1R, MW-2R MW-3S, MW-31D, MW-4, MW-5R, and MW-6 and sample surface water sample locations SW-1, SW-2, SW-3, and SW-4. 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. 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. Figure 3A, Potentiometric Map (January 2023) illustrates estimated groundwater flow across the landfill site based on the reported groundwater surface elevations during the January 2023 sampling event. Figure 313, Potentiometric Map (July 2022) illustrates estimated groundwater flow across the landfill site based on the reported groundwater surface elevations during the July 2022 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 2023. 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 sampling forms after purging and before sampling. Groundwater Sampling Methods Groundwater samples from each monitoring well were collected directly from a submersible pump or decanted from disposable bailers into the laboratory -prepared and -provided 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 -certified laboratory (Waypoint Analytical) under standard Chain -of -Custody (COC) protocol. Field data logs are provided in the Appendix I to this report. Surface Water SamDlinL- Methods 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 overfill the preserved sample containers (which could lead to preservative loss). To avoid sample -induced turbidity the samples were collected initially from the downstream sample location, SW-2, and in sequence upstream, SW-4, then SW-3, and then SW-1 to reduce potential turbidity in the samples (Figure 2). After sample collection, the samples were placed in a laboratory -provided cooler, chilled on ice to approximately 4°C, and submitted to Waypoint Analytical under standard COC protocol. 3.2 Quality Control Two duplicate samples were collected: one from MW-31D analyzed for Appendix I, MNA January 2023 Water Quality Monitoring Report WR Project Number 06140180.62 Town of Kernersville Closed Landfill, Permit 34-04 February 2023 Page 4 of 8 ■■ WithersRavenel ..

Two Trip Blanks were prepared by the laboratory to accompany the volatile sampling containers during shipment to and from the laboratory. The Trip Blanks were analyzed for VOCs only. 4.0 ANALYTICAL RESULTS 4.1 Groundwater Groundwater samples were analyzed for the Appendix I list, the modified list of MNA constituents, and 1,4-Dioxane and compared to the respective 2L Standards or GWPs where appropriate.
