Originally, the site of the closed Wilson County Landfill facility was dominated by a hill (approximately 108 feet above msl) located in the central portion of the present site. Several residential/farm houses were located in the northeast portion of the site. An intermittent stream originating in the northern portion of the site flowed southeastward eventually flowing into an unnamed stream southeast of the site. This unnamed stream flowed westward becoming part of the southern site boundary and traversed the southwestern most portion of the site and emptied into the Toisnot Swamp Canal. The remainder of the site contained drainage features that radiated outward from the dominant hill and discharged into these streams or with other drainage features located to the northwest of the site. Wetland areas were associated with streams and the Toisnot Swamp. Prior to construction of the landfill facility, agriculture was the primary land use in this area of Wilson County. Surrounding properties within 1,500 feet of the site are currently being used for farming, residential, or solid waste management purposes. Land south of the site is mostly farmland with a mobile home park located approximately 1,200 feet to the south. Land immediately west of the site is owned by Wilson County and used for construction and demolition debris disposal, recycling/reclaimation, and other solid waste management activities. Land north of the site is mostly used for farmland with wooded areas. Land east of the site is mostly farmland with wooded areas and light residential use. Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 2 1.2 Site Geology The closed Wilson County Landfill is located in the western portion of the Carolina Coastal Plain near the Fall Line. The Fall Line is the province boundary between the Piedmont and the Coastal Plain provinces. It represents a significant change in lithology, which in turn reflects a change in stream gradients. Lithology of the Piedmont province is primarily igneous and metamorphic while the Coastal Plain province is primarily sedimentary. In general, rivers and streams in the Piedmont province have higher flow rates with well-defined channels while Coastal Plain rivers and streams are meandering with lesser defined channels resulting in swamps and bays. These streams, swamps, and bays are the major discharge point of the uppermost aquifer. The Carolina Coastal Plain is underlain by flat-lying to very gently eastward dipping sedimentary strata which overlay a foundation of crystalline rocks. These sediments were deposited during repeated marine transgressive and regressive cycles due to fluctuations in sea level caused by expansion and recession of glacial ice caps during the Pliocene and early Pleistocene epochs (approximately 2 to 5 million years ago). Sediments in the area of the closed Wilson County Landfill facility are classified as being in the Yorktown Formation. Information gathered from the Geologic Map of North Carolina, 1985 and The Geology of the Carolina, 1991, cites that sediments of the Yorktown Formation are fossiliferous clay with varying amounts of fine-grained sand, silty sand, sandy silt, silty clay, and bluish gray shell material. These types of deposits are found mainly north of the Neuse River and are commonly concentrated in lenses and vary in vertical and horizontal dimensions. The topography of the Coastal Plain is characterized by flat to gently undulating relief. The local geology is characterized by relatively thin layers (0.5 - 7.0 feet) of clays, silts, and sands in varying textures and colors that overlie a gray/black silty clay/sand that is found throughout the area. The drainage canals located on the northwest and southeast Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 3 property boundaries expose these silty clay and sand layers. The original soils at the site were excavated to create capacity for waste disposal. 1.3 Site Hydrogeology The major groundwater discharge features influencing groundwater flow direction at the site are the Toisnot Swamp and drainage ditches located to the southeast and northwest of the site. Groundwater level measurements collected on October 4, 2017 indicate that the general groundwater flow direction on the facility is to the south-southeast towards the Toisnot Swamp Canal. However, the presence of drainage ditches have an impact on localized groundwater flow. Groundwater flow near the southeastern drainage ditch tends to be in a more southerly direction towards the drainage ditch. A Potentiometric Map indicating groundwater flow directions is provided as Figure 1. Aquifer hydraulic conductivity testing was performed in June 1997 on five of the site monitoring wells and consisted of rising and falling head tests (slug tests). The results of the slug test data was analyzed using the Bouwer and Rice method and are summarized on the table below: WELL ID HYDRAULIC CONDUCTIVITY (centimeters/second) TYPE OF TEST FORMATION MW-3A 3.80 x 10-5 Falling Yorktown P-3 1.27 x 10-4 Rising Alluvium/Yorktown MW-4 1.01 x 10-4 Rising Alluvium MW-4 5.89 x 10-4 Falling Alluvium MW-5 8.50 x 10-5 Rising Alluvium MW-5 2.06 x 10-4 Falling Alluvium MW-6 1.85 x 10-4 Rising Yorktown MW-6 6.53 x 10-4 Falling Yorktown MW-7 1.66 x 10-4 Rising Alluvium MW-7 1.95 x 10-4 Falling Alluvium Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 4 The geometric average of the shallow water table aquifer hydraulic conductivity is 2.56 x 10-4 cm/sec (0.73 feet per day). This value may be considered a reasonable estimate of the hydraulic conductivity of the shallow water table aquifer at the closed Wilson County Landfill site. Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 5 2.0 Water Quality Monitoring Program The water quality monitoring network at the closed Wilson County 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 nine groundwater monitoring wells located at the facility that comprise the existing groundwater monitoring system (Figure 1). Monitoring well MW-1A is located to the northwest of the landfill area and serves as the sidegradient groundwater monitoring well. This well is situated on the northwest edge of the drainage ditch that separates former fill and borrow areas. Monitoring well MW-2 is located at the entrance to the landfill at Landfill Road (SR 1503) and serves as the upgradient groundwater monitoring well providing background water quality. Monitoring well MW-3 is located on the landfill side of the drainage ditch on the southeast property boundary of the landfill. Monitoring well MW-3A, added in 2004, is also located on the southeastern side of the landfill but on the opposite side of the drainage ditch. Monitoring wells MW-4 and MW-5 are both located to the southwest and downgradient of the landfill but hydraulically upgradient of the Toisnot Swamp Canal. Monitoring wells MW-6 and MW-7 are located on the southeast border of the landfill. Monitoring well MW-8 is considered a side-gradient monitoring well to the west of the former landfill area. Table 4 provides monitoring well construction information including installation date, well depth/screened interval, survey elevations, and lat/long for each well location. Table 5 provides the estimated hydraulic conductivity values for select monitoring wells based on falling/rising head slug tests. Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 6 2.2 Surface Water Monitoring Network There are presently five surface water monitoring stations associated with the closed Wilson County Landfill. Surface water monitoring stations SW-1 and SW-2 are both located on the Toisnot Swamp Canal. The upstream sampling location (SW-1) is located approximately 400 feet northwest of the landfill property boundary. The downstream sampling location (SW-2) is located approximately 1,100 feet southeast of the landfill property boundary. The drainage canal located along the southeastern boundary of the landfill is monitored with surface water stations SW-3 and SW-4. The drainage canal located on the northwestern boundary of the landfill is monitoring with surface water station SW-5. Please note that surface water station SW-5 was dry at the time of sample collection. These surface water monitoring locations are shown on Figure 1. Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 7 3.0 Water Quality Sample Collection Samples of groundwater and surface water were collected in accordance with the approved Wilson County 1996 Water Quality Monitoring Plan and 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 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 3). 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 disposable laboratory 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, samples were 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. Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 8 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 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 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. Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 9 4.0 Laboratory Analysis The samples were analyzed for parameters specified by the 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 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. Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 10 5.0 Hydrogeological Conditions The depth to groundwater was measured in the nine compliance monitoring wells during the October 4, 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 3 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-southwest, toward the Toisnot Swamp Canal. Based on the results of prior hydrologic tests conducted at the site, groundwater flow rate in the shallow saprolite ranges from 0.108 ft/day to 1.85 ft/day. The average hydraulic conductivity and transmissivity values for the site are provided on Table 5. Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 11 6.0 Laboratory Analytical Results Final laboratory analytical results for the samples collected on October 4, 2017 were received from the analytical laboratory on October 17, 2017. A summary of the analytical results are provided on Table 1 (groundwater), Table 2 (surface water), and Table 3 (field parameters). 6.1 Groundwater Analytical Results During this monitoring event, four volatile organic compounds (VOCs) were reported above the laboratory reporting limits. Monitoring well MW-7 reported the compounds cis-1,2-dichloroethene, tetrachloroethene, trichloroethene, and vinyl chloride at concentrations above the laboratory method reporting limits. Of these four reported VOCs, only two compounds (tetrachloroethene – 1.5 ug/l and vinyl chloride – 1.7 ug/l) exceeded the NC 2L Groundwater Standard of 0.7 ug/l and 0.03 ug/l, respectively. No other VOCs were detected at concentrations exceeding the laboratory reporting limits, Solid Waste Section Limits (SWSLs), or the NC 2L Groundwater Standards in any of the remaining eight groundwater monitoring wells. No inorganic compounds were detected at a concentration that exceeded the NC 2L Groundwater Standards in any of the nine groundwater monitoring wells sampled during this monitoring event. The inorganic compound barium was reported above the laboratory detection limit and SWSL in monitoring wells MW-3A, MW-4, MW-5, and MW-7; however, the reported concentrations did not exceed the established NC 2L Groundwater Standard. The inorganic compound beryllium was reported above the laboratory detection limit and SWSL in monitoring wells MW-1A, MW-3 and MW-6; however, there is no established NC 2L Groundwater Standard for beryllium. Monitoring wells MW-1A and MW-6 also reported a detectable concentrations of cobalt, which does not have an established NC 2L Groundwater Standard. Monitoring wells MW-1A, MW- 3, MW-6, and MW-8 reported detectable concentrations of zinc, although the concentrations were well below the established NC 2L Groundwater Standard. A Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 12 summary of the groundwater laboratory analytical results and the corresponding NC 2L Groundwater Standards are provided on Table 1. 6.2 Surface Water Analytical Results The laboratory analytical report indicated no VOCs were present in any of the surface water samples above the SWSLs, laboratory detection limits, or 2B Surface Water Standards. The inorganic compound barium was reported above the laboratory reporting limit and SWSL in surface water sample SW-1. The reported barium concentration in SW-1 of 160 ug/l is well below the established 2B Surface Water Standard of 1000 ug/l. No other inorganic compounds were reported above the laboratory reporting limits, SWSLs, or NC 2B Surface Water Standards in the samples collected from the four surface water monitoring stations. Please note that surface water station SW-5 was dry at the time of sample collection. A summary of the surface water analytical results and corresponding NC 2B Surface Water Standard for the four surface water samples is provided on Table 2. 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. Wilson County Closed Landfill Water Quality Monitoring Report October 2017 Page 13 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 Wilson County Landfill will remain in Detection Monitoring in accordance with Title 15A NACA 13B .0601. The 2018 spring semi-annual water quality monitoring event is tentatively scheduled for May 2018.

The analyte was detected in the associated method blank. 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. The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. 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. MRL E U J D B PQL: Practical Quantitation Limit.PQL The internal standard(s) for this sample were outside the acceptance limits due to sample matrix interference. The sample was reanalyzed at a dilution. QI-03 Post-digestion spike did not meet method requirements due to confirmed matrix effects (dilution test). QM-08 Surrogate recovery outside acceptance limitsQS-03 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.
