Introduction 1.1 Site Information The City of Lexington Closed Landfill is located approximately two miles northeast of downtown Lexington, North Carolina on State Road 2001 in Davidson County, North Carolina. 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. City of Lexington Closed Landfill Water Quality Monitoring Report October 2015 Page 2 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. 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. City of Lexington Closed Landfill Water Quality Monitoring Report October 2015 Page 3 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 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 City of Lexington Closed Landfill Water Quality Monitoring Report October 2015 Page 4 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 (i.e. drainage features, fractured bedrock, and flood plain sediments). City of Lexington Closed Landfill Water Quality Monitoring Report October 2015 Page 5 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 location of the groundwater and surface water samples collected during the semi-annual monitoring events is 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 system (Figure 1). The northern boundary of the landfill is monitored by five wells; MW-4, MW-5, MW-6, MW-11, and MW-12. Monitoring well MW-11 is the upgradient sampling point which represents background groundwater quality. Although MW-4, MW-5, MW-6, and MW-12 are located on the hydraulically upgradient portion of the property, the water quality in these wells may be impacted by their close proximity to the former landfill disposal areas. 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. 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 October 2015 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. 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 well 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 sample collection to assure a fresh groundwater sample was 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 had 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 October 2015 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 accompanied 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 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 October 2015 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 analyses 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 October 2015 Page 9 5.0 Hydrogeological Conditions The depth to groundwater was measured in twelve compliance monitoring wells during the October 12-13, 2015 monitoring event. The background monitoring well MW-11 was dry during this 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 0.0136 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 0.035 ft/ft downward (groundwater recharge zone) MW-10/MW-10D 0.021 ft/ft upward (groundwater discharge 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 hydraulic conductivity values for the monitoring wells at the site are provided on Table 6. City of Lexington Closed Landfill Water Quality Monitoring Report October 2015 Page 10 6.0 Laboratory Analytical Results Final laboratory analytical results for the samples collected on October 13, 2015 were received from the analytical laboratory on October 27, 2015. A summary of the analytical results are provided on Table 1 & 2 (groundwater), Table 3 (surface water), and Table 4 (field parameters). 6.1 Groundwater Analytical Results The groundwater analytical results indicate four volatile organic compounds (VOCs) present at concentrations exceeding the Solid Waste Section Limits (SWSLs), with two of the reported compounds exceeding the NC 2L Groundwater Standards. The compound benzene was reported in monitoring well MW-5 at a concentration of 1.5 ug/l, which is slightly above the 2L Groundwater Standard of 1.0 ug/l. The chlorinated compound 1,4-dichlorobenzene was reported in monitoring wells MW-2 (2.0 ug/l), MW-5 (9.7 ug/l), MW-7 (7.6 ug/l), MW-7D (1.1 ug/l), and MW-8 (1.5 ug/l). The concentration of 1,4-diclorobenzene in monitoring wells MW-5 and MW-7 slightly exceed the NC 2L Groundwater Standard of 6.0 ug/l. The compound chlorobenzene was reported in monitoring wells MW-7 (3.4 ug/l) and MW-8 (15.0 ug/l), which is well below the NC 2L Groundwater Standard of 50.0 ug/l. Finally, the compound acetone was reported in monitoring well MW-5 at a concentration of 34.0 ug/l which is also well below the NC 2L Groundwater Standard of 6,000 ug/l. A summary of the detected volatile organic compounds and the respective 2L Groundwater Standards is provided on Table 2, which is included with this report. Inorganic compounds were detected at concentrations exceeding the SWSLs and laboratory detection limits in seven of the twelve 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 well MW-6 (51.4 ug/l) and MW-12 (12.3 ug/l) City of Lexington Closed Landfill Water Quality Monitoring Report October 2015 Page 11 slightly exceed 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 twelve landfill groundwater monitoring wells. A summary of the detected inorganic compounds and the respective 2L Groundwater Standards is provided on Table 1. 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. No VOCs were detected above the SWSLs or laboratory reporting limits in the upstream or downstream surface water sample. In addition, only one inorganic compound was reported above the SWSLs and laboratory reporting limits. The inorganic compound zinc was reported at a concentration of 36.4 ug/l in the upstream surface water sample SW-1. This reported concentration is below the NC 2B Surface Water Standard for zinc of 50.0 ug/l. No other inorganic compounds were reported above the SWSLs, laboratory detection limits, or NC 2B Surface Water Standards in either of the two surface water samples. 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 October 2015 Page 12 7.0 Conclusions The results of this monitoring event report only minor variants from the established NC 2L Groundwater Standards and NC 2B Surface Water Standards. Based on the results of this water quality monitoring event, the closed City of Lexington Landfill will remain in Detection Monitoring in accordance with Title 15A NCAC 13B .0601.

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.
