On May 1, 2017 ten groundwater monitoring wells were sampled and analyzed for Appendix I parameters. One upgradient surface water monitoring station (SW-1) and one downgradient surface water monitoring station (SW-4) were also sampled for Appendix I parameters during this monitoring event. The Appendix I samples were analyzed for volatile organic compounds (VOCs) by EPA Method 8260B and inorganic compounds by EPA Method 6010B. In accordance with the approved February 2016 City of Lexington Closed Landfill Water Quality Monitoring Plan, semi-annual monitoring will not be required in the fall of 2017. As no volatile organic compounds were reported above the 2L Groundwater Standards during this monitoring event, the landfill will perform annual water quality monitoring at the site. If future water quality monitoring events indicate volatile organic compounds are present above the 2L Groundwater Standards, the site will revert back to semi-annual monitoring. A site map is provided with this report which shows the groundwater and surface water sample locations and shallow potentiometric surface (Figure 1). An isoconcentration map showing the estimated volatile organic compound concentrations is provided as Figure 2. Additional attachments to this report include tables summarizing the groundwater and surface water analytical results (Tables 1, 2, and 3), field parameters collected during the monitoring event (Table 4), well construction information (Table 5), and groundwater flow rates (Table 6). The laboratory analytical report, in pdf and EDD formats, is included as Appendix A. If you have any questions or if additional information is needed, please contact me at (919) 325-0696.

The landfill ceased operation on May 1, 1990 and was closed by capping the fill with a four-foot thick final cover using native soils. The northern boundary of the landfill is established by the Southern Railroad which traverses the property from southwest to the northeast. The eastern, southern, and western portions of the landfill are bordered by Abbotts Creek which flows in a general southwesterly direction. Properties adjacent to the closed landfill are either undeveloped woodland or farmland. Property usage to the south and east is primarily undeveloped woodland, farmland, and residential. Undeveloped woodland and residential properties are also present to the north of the landfill. Properties to the immediate west are undeveloped woodland. Several industrial/commercial facilities are located along US Highway 64, located approximately 2,300 feet west/northwest of the landfill. 1.2 Site Geology The subject property is located in the Carolina Slate Belt, which is part of the Piedmont Physiographic Province of North Carolina. The geology of the Carolina Slate Belt is characterized by metavolcanic and metamorphosed intrusive rock sequences. According to the Geologic Map of North Carolina published by the Department of Natural Resources and Community Development (Brown, 1985), the rocks underlying the subject property are metavolcanic rocks consisting of interbedded felsic to mafic tuffs and flowrock. City of Lexington Closed Landfill Water Quality Monitoring Report May 2017 Page 2 According to the Geologic Map of The Charlotte Quadrangle, North Carolina and South Carolina (Goldsmith, Milton, and Horton, 1988), the rocks underlying the landfill are interbedded felsic and mafic metavolcanic rocks. The metavolcanic rocks are fine to medium grained with locally coarse grained or agglomeratic rocks of basaltic, andesitic, and dacitic composition. This report identified a fault located between the landfill property and US Highway 64 which is oriented in a northeast/southwest direction. The general course of Abbotts Creek changes from a southwesterly direction to a south/southwest direction at the landfill following this fault. 1.3 Site Hydrogeology The observed subsurface conditions at the landfill consist of white to gray/green metavolcanic bedrock overlain by weathered saprolitic soil. The soil at the site is comprised of a mixture of clay, silt, and sand. The majority of the original soil profile on the landfill property has been altered during landfill operations to the extent that it is no longer recognizable. The northern section of the landfill is characterized by a layer of silty clay and sandy silt soil that overlies metavolcanic bedrock. The thickness of the soil varies from greater than 43' at monitoring well MW-5 to 9' at monitoring well MW-6. The eastern section of the landfill is characterized by a layer of silty clay and silty sand soil that also overlies metavolcanic bedrock. The thickness of the soil in this area varies from 18' at monitoring well MW-8 to 38' at monitoring well MW-7. The southern section of the landfill is characterized by a layer of sandy clay to clayey silt soil. Fine sandy clay was present beneath these layers in monitoring well MW-10. Bedrock was not encountered during well installation activities in the southern section of the landfill. A series of rising head slug tests were conducted in nine of the landfill monitoring wells on October 23-24, 1996. An In-Situ model SE 1000C Hermit Data Logger system with City of Lexington Closed Landfill Water Quality Monitoring Report May 2017 Page 3 submersible pressure transducers was used to record the water level changes in each well during the slug tests. The transducers were first lowered into the well and placed a minimum of ten feet below the static water level. A disposable bailer was then placed in the well so that the top of the bailer was just below the groundwater surface. The aquifer was allowed to stabilize for approximately 30 minutes prior to starting each test. After stabilization the bailer was quickly removed from the well causing a rapid change in the groundwater level. The data logger recorded changes in the water table every five seconds and the levels stabilized. The Bouwer and Rice method was used to evaluate the results and calculate hydraulic conductivity (K). The calculated K for the nine wells resulted in the following: MW-2: K = 0.438 ft/day MW-3: K = 0.0494 ft/day MW-4: K = 0.323 ft/day MW-5: K = 0.0812 ft/day MW-6: K = 1.04 ft/day MW-7 K = 0.0127 ft/day MW-8: K = 0.0565 ft/day MW-9: K = 2.66 ft/day MW-10: K = 0.327 ft/day The hydraulic conductivity (K) represents an approximation of the permeability of the subsurface materials which transmit groundwater. In the monitoring wells evaluated at the landfill, the estimated permeability values ranged from a minimum of 0.0127 ft/day to a maximum of 2.66 ft/day, with the average value of 0.506 ft/day. These values are within the typical range for saprolitic soil. The variability of the values seen here may reflect the various geologic features encountered, including drainage features, fractured bedrock, and/or floodplain sediments. City of Lexington Closed Landfill Water Quality Monitoring Report May 2017 Page 4 2.0 Water Quality Monitoring Program The water quality monitoring network at the closed City of Lexington Landfill is evaluated on a semi-annual basis. The locations of the groundwater and surface water samples collected during the semi-annual monitoring events are shown on the attached Figure 1. 2.1 Groundwater Monitoring Network There are thirteen groundwater monitoring wells located at the facility that comprise the existing groundwater monitoring network (Figure 1). Monitoring well MW-12 is the upgradient sampling point which represents background groundwater quality. The northern boundary of the landfill is monitored by five wells; MW-4, MW-5, MW-6, MW- 11, and MW-12. The eastern boundary of the landfill is monitored by four wells; MW-7, MW-7D, MW-8, and MW-3. The southern boundary of the landfill, along Abbotts Creek, is monitored by four wells; MW-2, MW-9, MW-10, and MW-10D. Information regarding the date of installation, construction specifics, formation material encountered, and Lat/Long location of the thirteen groundwater monitoring wells is provided on Table 5. Monitoring wells MW-4, MW-5, and MW-12 are located on the hydraulically upgradient portion of the property, however, the water quality in these wells may be impacted by their close proximity to the former landfill disposal areas. As such, these three well are gauged for water levels only, no sample is collected for laboratory analyses. The monitoring wells evaluated by laboratory analyses during each monitoring event include: MW-2 MW-3 MW-6 MW-7 MW-7D MW-8 MW-9 MW-10 MW-10D MW-11 City of Lexington Closed Landfill Water Quality Monitoring Report May 2017 Page 5 2.2 Surface Water Monitoring Network In addition to the on-site groundwater monitoring wells, two surface water samples are collected from Abbotts Creek. A surface water sample is collected upstream (SW-1) and downstream (SW-4) of the landfill from Abbotts Creek. The location of the surface water samples is shown on Figure 1. City of Lexington Closed Landfill Water Quality Monitoring Report May 2017 Page 6 3.0 Water Quality Sample Collection Samples of groundwater and surface water were collected in accordance with the 2008 NC Solid Waste Section Guidelines for Groundwater, Soil, and Surface Water Sampling Guidance Document and the approved February 2016 City of Lexington Closed Landfill Water Quality Monitoring Plan. A brief description of the sample collection procedure is provided below. 3.1 Field Sample Procedures Prior to groundwater sampling, water levels are obtained from each of the thirteen monitoring wells using an electric water level meter capable of measuring the depth to water to the nearest 0.01 feet. This information is later used to determine the elevation of the water table in each monitoring well relative to surveyed datum (Table 4). The depth to water in each well is also used to determine the volume of standing water in the well casing. This information allows for the purging of a minimum of three casing volumes from each well prior to sampling to assure a fresh groundwater sample is collected. New disposable laboratory gloves are worn by sampling personnel and each well is purged and sampled with a new disposable bailer which is discarded after use. After the monitoring wells have been allowed to recover from purging, samples are collected in the following order:  Volatile organic compounds  Inorganic compounds  Field Parameters (pH, Conductivity, Temperature) The samples are collected directly in the laboratory-supplied containers which are pre- filled with the appropriate preservative. No filtering of the samples is performed prior to collection. After collection, the samples are placed in a cooler on ice for overnight shipment to the analytical laboratory. City of Lexington Closed Landfill Water Quality Monitoring Report May 2017 Page 7 Surface water samples are collected directly into the laboratory-supplied containers as grab samples. Sampling personnel wear new disposable laboratory gloves for each surface water sample collected. As with the groundwater samples, these samples are stored in a cooler on ice prior to overnight delivery to the analytical laboratory. 3.2 Field Quality Assurance One trip blank sample is prepared by the analytical laboratory and accompanies the sample shipment until receipt back at the laboratory. The trip blank sample is 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 and surface water samples are stored in coolers on ice immediately after collection. Individual sample containers for each well or surface water sample are placed in individual zip lock plastic bags to reduce the potential for cross contamination. 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. City of Lexington Closed Landfill Water Quality Monitoring Report May 2017 Page 8 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 by EPA Method 8260B and select inorganic compounds by EPA Methods 6010C/6020A. 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. City of Lexington Closed Landfill Water Quality Monitoring Report May 2017 Page 9 5.0 Hydrogeological Conditions The depth to groundwater was measured in all thirteen compliance monitoring wells during the May 1, 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 4 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 Abbotts Creek. Based on the observed groundwater elevations at the site, the hydraulic gradient of the shallow water table from north to south is 0.0142 ft/ft. The vertical component of groundwater flow was evaluated using the two nested pairs of landfill monitoring wells. The following vertical groundwater gradients were observed: MW-7/MW-7D 0.047 ft/ft downward (groundwater recharge zone) MW-10/MW-10D 0.031 ft/ft downward (groundwater recharge zone) Based on the results of prior field tests performed at the site, the estimated groundwater flow rate in the saprolitic soil ranges from 0.0127 ft/day to 2.66 ft/day, with an average value of 0.506 ft/day. The estimated hydraulic conductivity values for the monitoring wells at the site are provided on Table 6. City of Lexington Closed Landfill Water Quality Monitoring Report May 2017 Page 10 6.0 Laboratory Analytical Results Final laboratory analytical results for the samples collected on May 1, 2017 were received from the analytical laboratory on May 18, 2017. A summary of the analytical results are provided on Tables 1 and 2 (groundwater), Table 3 (surface water), and Table 4 (field parameters). 6.1 Groundwater Analytical Results Inorganic compounds were detected at concentrations exceeding the Solid Waste Section Limits (SWSLs) and/or laboratory detection limits in five of the ten groundwater monitoring wells sampled during this monitoring event. Only one inorganic compound was detected at a concentration that exceeded the established NC 2L Groundwater Standards. The concentration of chromium in monitoring wells MW-6 (22.6 ug/l), MW- 9 (15.9 ug/l), and MW-10 (13.8 ug/l) slightly exceeds the established 2L Groundwater Standard for chromium of 10.0 ug/l. No other inorganic compounds were reported above the established 2L Groundwater Standards in any of the ten landfill groundwater monitoring wells. A summary of the detected inorganic compounds and the respective 2L Groundwater Standards is provided on Table 1. The groundwater analytical results indicate two volatile organic compounds (VOCs) present at concentrations exceeding the SWSLs. The chlorinated compound 1,4- dichlorobenzene was reported in monitoring well MW-7d (1.4 ug/l), and MW-8 (1.1 ug/l). The reported concentrations of 1,4-diclorobenzene in these two monitoring wells do not exceed the NC 2L Groundwater Standard of 6.0 ug/l. The compound chlorobenzene was reported in monitoring well MW-8 (14.0 ug/l), which is also below the NC 2L Groundwater Standard of 50.0 ug/l. No other VOCs were reported above the laboratory reporting limits or SWSLs in any of the remaining monitoring wells at the site. A summary of the detected volatile organic compounds and the respective 2L Groundwater Standards is provided on Table 2 with this report. City of Lexington Closed Landfill Water Quality Monitoring Report May 2017 Page 11 6.2 Surface Water Analytical Results Surface water samples were collected from the SW-1 upstream monitoring station and the SW-4 downstream monitoring station (Figure 1). No VOCs were detected above the SWSLs or laboratory reporting limits in the upstream or downstream surface water samples. Several inorganic compounds were reported above the SWSLs or laboratory reporting limits in the upstream surface water sample. The inorganic compounds barium, chromium, cobalt, copper, lead, vanadium, and zinc were reported above the laboratory reporting limit and SWSLs in the upstream SW-1 sample. Three of these inorganic compounds (cobalt – 17.7 ug/l; copper – 28.4 ug/l; and zinc – 72.9 ug/l) exceed the established 2B Surface Water Standards in the upstream surface water sample. No inorganic compounds were reported above the laboratory reporting limits or SWSLs in the downgradient SW-2 surface water sample. A summary of the laboratory analytical results and the applicable 2B Surface Water Standards are provided on Table 3. 6.3 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. City of Lexington Closed Landfill Water Quality Monitoring Report May 2017 Page 12 7.0 Conclusions The results of this monitoring event reported only minor variants from the established NC 2L Groundwater Standards in five of the ten groundwater monitoring wells sampled at the landfill. Surface water samples collected on Abbotts Creek did not report any detectable concentrations above the laboratory detection limits or the NC 2B Surface Water Standards in the surface water sample collected downgradient of the landfill. Based on the results of this water quality monitoring event the closed City of Lexington Landfill will remain in Detection Monitoring pursuant to Title 15A NCAC 13B .0601. In accordance with the approved February 2016 City of Lexington Closed Landfill Water Quality Monitoring Plan, semi-annual monitoring will not be required in the fall of 2017. As no volatile organic compounds were reported above the 2L Groundwater Standards during this monitoring event, the landfill will perform annual water quality monitoring at the site. If future water quality monitoring events indicate volatile organic compounds are present above the 2L Groundwater Standards, the site will revert back to semi-annual monitoring. The 2018 spring annual water quality monitoring event is tentatively scheduled for April/May 2018. Attachments to this report include tables summarizing the groundwater and surface water analytical results (Tables 1, 2, and 3), field parameters collected during the monitoring event (Table 4), well construction information (Table 5), and hydrologic test results (Table 6). A potentiometric map of the shallow water table is provided as Figure 1 and an isoconcentration map of the total volatile organic compounds is provided as Figure 2.

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. This compound is a common laboratory contaminant.O-01 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact. QL-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 The spike recovery was outside acceptance limits for the MS and/or MSD.QM-19 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.
