The surrounding area is mixed residential, commercial, and industrial land uses. The MSWLF facility is located on approximately 164 acres owned by the City of High Point. The permitted facility is bounded on the north by Kivett Drive, on the west by Jackson Lake Road, and to the south by private property. Kersey Valley Road runs through the center of the site and separates the Area 1 and Area 2 landfill units. Two unnamed tributaries of Richland Creek (“South” and “East” tributaries) run along much of the southern portion of the site between the landfill units and neighboring properties. Also, a pond exists on the site just to the west of the Area 1 landfill unit. Ground surface elevations range from approximately El. 740 msl along the unnamed tributary on the south end of the site to El. 900 msl at the top of the Area 1 landfill unit. The facility location and existing site conditions are shown on Figure 1. 1.2 Site Geology1 The Kersey Valley MSWLF is located in the central Piedmont Physiographic Province, in the northern portion of the Carolina Slate Belt. Granite is the predominant rock type in the area and outcrops are observed along the creeks and within the site. Rock core ____________________ 1 Water Quality Monitoring Plan – Kersey Valley Landfill Facility, Smith Gardner, Inc., November 2014 Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 2 borings indicated a light tan to pinkish white, medium to coarse grained porphyritic granite with abundant quartz, potassium feldspar and mica. Granite exposures at the surface are generally highly weathered but become less weathered with depth. Site stratigraphy includes three main layers: 1) near surface soils which include moderate to high plasticity silt and clay, low plasticity sandy silt and clayey silt; 2) weathered rock (saprolite); and 3) bedrock. Near surface soils generally have standard Penetration Test (SPT) values ranging from 20-50 blows per foot (bpf). The saprolite generally has SPT values of >50 bpf. No unusual geologic features or conditions were identified during prior site studies. 1.3 Site Hydrogeology1 Groundwater in the upper-most aquifer generally flows through unconsolidated sediments and secondary fractures in the underlying bedrock. Recharge occurs primarily in the northern portion of the site and is limited on slopes. Groundwater flows generally south where it discharges into two unnamed tributaries of Richland Creek. The groundwater potentiometric surface generally reflects a subdued expression of the surface topography. Local conditions are considered typical for the central Piedmont Region. A composite potentiometric surface map for the site is provided as Figure 1. ____________________ 1 Water Quality Monitoring Plan – Kersey Valley Landfill Facility, Smith Gardner, Inc., November 2014 Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 3 2.0 Water Quality Monitoring Program The water quality monitoring network at the Kersey Valley MSWLF is evaluated on a semi- annual basis. The location of the groundwater, surface water, and landfill leachate samples collected during the semi-annual monitoring events is shown on the attached Figure 1. 2.1 Groundwater Monitoring Network The existing groundwater monitoring network consists of fourteen shallow aquifer wells which are screened across the water table in the partially weathered rock, just above the depths of auger refusal. The fourteen monitoring wells sampled for subsequent laboratory analysis include: MW-1 (background) MW-3A MW-4 MW-6A MW-8A MW-9 MW-10 MW-11 MW-12 MW-13S MW-14 MW-15 MW-16 MW-17 In addition to the fourteen monitoring wells sampled for laboratory analysis, four deeper aquifer monitoring wells are gauged for water levels. This provides information on the vertical component of groundwater flow at the site. The four deeper aquifer monitoring wells include: MW-7D MW-8B MW-9D MW-13D Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 4 The shallow wells have been constructed in boreholes advanced to the top of rock (defined by refusal) using 6-inch diameter hollow stem augers. The deeper aquifer monitoring wells are screened within the bedrock having been advanced below auger refusal depths using air-rotary or rock coring techniques. All monitoring wells are constructed of 2-inch diameter Schedule 40 PVC, with an isolated well screen interval, in accordance with applicable NC Well Construction Standards. Monitoring well construction information is provided on Table 5. 2.2 Surface Water Monitoring Network The current surface water monitoring network consists of eight monitoring stations as shown on Figure 1. The surface water monitoring stations are located along the south side of Area 1 and the south/southeast side of Area 2 of the landfill. The eight surface water stations sampled for the water quality monitoring program include: SW-1 (background) SW-3 SW-5 SW-6 SW-7 SW-8 SW-9 SW-10 2.3 Landfill Leachate Monitoring Landfill leachate samples are collected from Area 1 (Leachate Phase 1-3) and Area 2 (Leachate Phase 4-5). The leachate sample collected from the leachate storage lagoon in the south central portion of the site represents Area 1. The leachate sample collected from the leachate storage tank facility in the northeast corner of the site represents Area 2. The location of these two leachate collection points is shown on the attached Figure 1. Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 5 3.0 Water Quality Sample Collection Samples of groundwater, surface water, and leachate were collected in accordance with the approved Water Quality Monitoring Plan, November 2014 and the NC Solid Waste Section Guidelines for Groundwater, Soil, and Surface Water Sampling Guidance Document, 2008. A description of the sample collection procedure is provided below. 3.1 Field Sample Procedures Prior to groundwater sampling, water levels were obtained from each well using an electric water level meter capable of measuring the depth to water to the nearest 0.01 feet. This information was later used to determine the elevation of the water table in each monitoring well relative to surveyed datum (Table 5). The depth to water in each well was also used to determine the volume of standing water in the well casing. This information allowed for the purging of a minimum of three casing volumes from each well prior to sample collection to assure a fresh groundwater sample was collected. New nitrile gloves were worn by sampling personnel and each well was purged and sampled with a new disposable bailer which was discarded after use. After the monitoring wells had been allowed to recover from purging, normally 12-14 hours, samples are collected in the following order:  Volatile organics  Total metals  Inorganics (nitrate, phosphorus, sulfate)  Biological (BOD, COD)  Field Parameters (pH, Conductivity, Temperature) Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 6 The groundwater samples are collected directly in the laboratory-supplied containers which are pre-filled with the appropriate preservative. The samples are not filtered in the field or the laboratory. After collection, the samples are placed in a cooler on ice for shipment to the analytical laboratory. Surface water and landfill leachate samples are collected directly into the laboratory- supplied containers as grab samples. Sampling personnel wear new disposable nitrile gloves for each surface water and leachate sample collected. As with the groundwater samples, these samples are stored in a cooler on ice prior to delivery to the analytical laboratory. 3.2 Field Quality Assurance One trip blank sample was prepared by the analytical laboratory and accompanied the sample shipment until receipt back at the laboratory. The trip blank sample was analyzed for volatile organic compounds. Temperature blanks are also provided with the sample shipments to assure the proper temperature is maintained until delivery to the analytical laboratory. 3.3 Sample Delivery/Chain of Custody All groundwater, surface water, and landfill leachate samples are stored in coolers on ice immediately after collection. Individual sample containers for each monitoring well or surface water sample are placed in zip lock plastic bags to reduce the potential for cross contamination between sample locations. Chain-of-Custody control documents are prepared and shipped with each cooler. Custody seals are also used for each cooler to maintain sample integrity until delivery to the analytical laboratory. The sample coolers are shipped via Federal Express for next morning delivery to the analytical laboratory. Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 7 4.0 Laboratory Analysis The samples were analyzed for parameters specified by the NC Solid Waste Section for detection monitoring at permitted solid waste facilities. The standard detection monitoring program for groundwater and surface water samples consists of the Appendix I parameters. The Appendix I analysis consists of volatile organic compounds (VOCs) by EPA Method 8260B and inorganic compounds by EPA Methods 6010C/6020A. In addition to the Appendix I parameters, the two leachate samples are analyzed for biological oxygen demand (SM 5210B-2001), chemical oxygen demand (SM5220D-1997), phosphorus (EPA Method 365.4), sulfate (EPA Method 300.0), and nitrate/nitrite (EPA Method 353.2). The laboratory performing the water quality analysis is Environmental Conservation Laboratories, Inc. (ENCO) of Cary, North Carolina, which is a NC Certified Laboratory. Internal quality control samples, including matrix spikes/matrix spike duplicates, are performed by ENCO for each set of samples. The ENCO laboratory report, including internal quality control samples, is provided with this report in Appendix A. Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 8 5.0 Hydrogeological Conditions The depth to groundwater was measured in the fourteen compliance monitoring wells and the four deeper aquifer monitoring wells during the May 2-3, 2017 monitoring event. The groundwater elevations were calculated relative to the surveyed measuring point (top of casing) for each monitoring well. The groundwater elevations are summarized on Table 5 and the potentiometric surface of the shallow water table is shown on Figure 1. The general direction of groundwater flow, based on the water level information collected during this monitoring event, is also shown on Figure 1. Groundwater flow direction is generally to the south, toward an unnamed tributary of Richland Creek. Based on the results of prior hydrological tests conducted in Area 1 of the site, groundwater flow rates in the shallow saprolite range from 1.24 ft/day to 2.38 ft/day. The hydrologic tests conducted in Area 2 in the fractured bedrock indicated groundwater flow rates in the range of 0.124 ft/day to 0.690 ft/day. The average hydraulic conductivity and transmissivity values for Areas 1 and 2 of the MSWLF are provided on Table 6. The vertical component of groundwater flow is determined from an evaluation of groundwater elevations observed in nested well pairs. Three nested pairs of monitoring wells were evaluated for vertical groundwater flow at the site. The following vertical groundwater gradients were determined from the elevations determined during the May 2017 monitoring event: Monitoring Wells MW-8A/8B 0.092 ft/ft downward Monitoring Wells MW-9/9D 0.078 ft/ft downward Monitoring Wells MW-13S/13D 0.004 ft/ft downward Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 9 6.0 Laboratory Analytical Results Final laboratory analytical results for the samples collected on May 3, 2017 were received from the analytical laboratory on May 23, 2017. A summary of the analytical results are provided on Table 1 (groundwater), Table 2 (surface water), Table 3 (field parameters), and Table 4 (landfill leachate). 6.1 Groundwater Analytical Results One volatile organic compound (VOCs) was detected at a concentration equaling or exceeding the laboratory method reporting limit at the site. The compound toluene was reported at a concentration of 1.1 ug/l in monitoring well MW-1 and MW-12. Note that monitoring well MW-1 is the upgradient background monitoring location for the site. The reported toluene concentration in the two monitoring wells is below the established NC 2L Groundwater Standard of 600 ug/l. No other VOCs were reported above the laboratory reporting limits or Solid Waste Section Limits (SWSL) in any of the remaining twelve monitoring wells. Four inorganic compounds were detected above the laboratory reporting limits and SWSLs, including barium, chromium, cobalt, and zinc. The reported concentration of barium in monitoring wells MW-6A, MW-9, MW-11, MW-12, MW-13S, MW-14, MW- 15, and MW-17 were all above the SWSL but well below the established NC 2L Groundwater Standard of 600 ug/l. The compound cobalt was reported above the SWSL in monitoring wells MW-6A, MW-9, and MW-13S. The compound cobalt does not have an established NC 2L Groundwater Standard. The compound zinc was reported above the SWSL in MW-1, MW-4, MW-6A, MW-9, MW-10, MW-11 MW-12, and MW-13S, however, the reported concentrations of zinc in these monitoring wells were all well below the established NC 2L Groundwater Standard of 1,000 ug/l. The inorganic compound chromium was reported above the SWSL and NC 2L Groundwater Standard Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 10 in monitoring well MW-9. The reported concentration of chromium in monitoring well MW-9 (16.8 ug/l) slightly exceeded the established NC 2L Groundwater Standard of 10 ug/l. No other inorganic compounds were reported at a concentration which exceeded the laboratory reporting limits, SWSLs, or NC 2L Groundwater Standards. 6.2 Surface Water Analytical Results No VOCs were detected at a concentration equaling or exceeding the laboratory method reporting limit in any of the eight surface water samples. Only one inorganic compound was detected at concentrations that exceeded the laboratory method reporting limit. The reported concentration of zinc (12.4 ug/l) in SW-6 was reported above the laboratory reporting limit and SWSL but well below the established 2B Surface Water Standard of 50 ug/l. No other inorganic compounds were detected in the eight surface water samples above the laboratory reporting limits, SWSLs, or NC 2B Surface Water Standards. Please note that surface water monitoring station SW-9 was dry at the time of this water quality monitoring event. Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 11 6.3 Landfill Leachate Analytical Results No volatile organic compounds were identified above the laboratory limits or SWSLs in either of the two landfill leachate samples. Several inorganic compounds were detected at a concentration equaling or exceeding the laboratory method reporting limits in the two leachate samples, including: barium, chromium, cobalt, and zinc. Additional parameters evaluated in the two leachate samples include: BOD (42,000 ug/l), COD (270,000 ug/l), phosphorus (790 ug/l), nitrite/nitrate (2,800 ug/l), and sulfate (14,000 ug/l-estimated). Please refer to Table 4 for a full summary of the reported VOCs, inorganics, and other indicator compounds in the two leachate samples. 6.4 Quality Control Sample One trip blank was submitted and analyzed for quality assurance purposes. No VOCs were detected at a concentration equaling or exceeding laboratory quantitation limits in the trip blank. Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 12 7.0 Historical Data Comparison A review of the laboratory analytical data for the groundwater samples collected over past monitoring events indicate the presence of low concentrations of naturally occurring inorganic compounds (i.e. barium, zinc). No volatile organic compounds have been reported in any of the groundwater monitoring wells above the NC 2L Groundwater Standards. The reported concentration of naturally occurring inorganic compounds vary slightly between monitoring events, likely due to fluctuating amounts of silt/sediment in the samples. Filtering of the groundwater samples prior to laboratory analysis is not allowed. Kersey Valley MSWLF Water Quality Monitoring Report May 2017 Page 13 8.0 Conclusions Based on the results of this water quality monitoring event, the Kersey Valley MSWLF will remain in Detection Monitoring in accordance with Title 15A NACA 13B .1633. The 2017 fall semi-annual water quality monitoring event is tentatively scheduled for October 2017. Attachments to this report include tables summarizing the groundwater and surface water analytical results (Tables 1 & 2), field parameters collected during the monitoring event (Table 3), landfill leachate analytical results (Table 4), well construction information (Table 5), and hydrologic test results (Table 6).

D The sample was analyzed at dilution. J The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery.

U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. The RPD and/or percent recovery for this QC spike sample cannot be accurately calculated due to the high concentration of analyte present in the sample. QM-02 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. QM-07 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.QM-11 The Reporting Limits for this analysis are elevated due to sample foaming.R-04 Page 20 of 21 Page 20 of 22 Page 21 of 22 Page 22 of 22
