The Westside C&D facility is located on property that was previously used as a borrow site for the closed landfill site which is located approximately 350 feet to the east of the Westside C&D property boundary. The western boundary of the site is established by the center-line run of Buck Branch. The adjoining properties on the west and east are owned by Wilson County. To the west, Wilson County has purchased the 76 acre property identified as the Mohesky Farm which provides additional off-site borrow resources for Wilson County Landfill projects. The closed Wilson County Landfill site is located due east of the Westside C&D site. Property further south of the Westside C&D facility is wooded and contains wetlands associated with the Toisnot Swamp. Prior to construction of the Westside C&D 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 wooded land with wetlands associated with the Toisnot Swamp. Land immediately west of the site is owned by Wilson County and used for 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 occupied by the closed Wilson County Landfill. 1.2 Site Geology The Westside C&D facility 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 Westside C&D Facility Water Quality Monitoring Report April 2016 Page 2 Coastal Plain provinces. It represents a significant change in lithology, which also 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 Westside C&D 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. 1.3 Site Hydrogeology The subsurface conditions observed at the site reflects the regional Coastal Plain characteristics. The depositional environment is influenced by Buck Branch and Toisnot Westside C&D Facility Water Quality Monitoring Report April 2016 Page 3 Swamp where the fluvial sediments are mixed with marine sediments in an estuarine setting. Where these streams once flowed into the Atlantic Ocean, a much broader river was likely present. Swift currents during flood conditions may have deposited lenticular beds of sand and other sediments. Incoming tidal currents rework the stream sediments, creating alternating layers of fluvial and marine sediments. The local stratigraphy is characterized by relatively thin layers of fluvial and marine silt, sand, and clay in varying textures and colors. Typically, the color of fluvial sediments are tan, brown, light grey or orange. With the unconformities expected in the depositional environment, the typical profile includes a lean clay overlying poorly graded sands, interbedded with thin clay and clayey sand lenses. The water bearing zone is present in coarse and well graded sand layers, typically beneath surficial clay. Below the fluvial sediments, a marine clay layer is consistently encountered. This marine clay unit is typically dark grey, fat, and laminated with microlenses of fine sand. Below the marine clay, a dark greenish grey silty clayey sand overlies the residual, fully weathered bedrock. The bedrock was encountered approximately 30-35 feet below the disturbed land surface, at an elevation of 60 to 64 feet mean sea level. Aquifer testing was conducted on six wells at the Westside C&D Landfill site. The aquifer testing was performed on February 12-13, 2003 and consisted of rising and falling head tests (slug tests) on wells P-103, P-104, P-105, P-106, P-108, and P-109. The purpose of the tests were to assess the values of horizontal hydraulic conductivity (K) at various locations within the water table aquifer. The results of the aquifer tests are provided below: Westside C&D Facility Water Quality Monitoring Report April 2016 Page 4 Well Number Test Type K (centimeters/second) P-103 (GMW-3) Falling 5.54 x 10-4 P-104 Falling 7.02 x 10-2 P-104 Rising 1.05 x 10-1 P-105 Falling 1.03 x 10-2 P-105 Rising 1.50 x 10-2 P-106 Falling 3.23 x 10-4 P-108 Falling 2.25 x 10-3 P-108 Rising 1.84 x 10-3 P-109 Falling 4.01 x 10-4 The aquifer testing performed for the site indicates that the upper water table aquifer provides hydraulic conductivity values which are directly related to presence of low permeability clays. The average hydraulic conductivity value for wells completed in primarily sandy material (P-104, P-105, P-108) is 4.09 x 10-2. The average hydraulic conductivity for wells completed in primarily clayey material (P-103, P-106, P-109) is 3.29 x 10-4. Based on the heterogeneity of the subsurface materials encountered during installation of the wells, the hydraulic conductivity is expected to vary based on the presence/absence of clayey soil. Westside C&D Facility Water Quality Monitoring Report April 2016 Page 5 2.0 Water Quality Monitoring Program The water quality monitoring network at the Westside C&D facility is evaluated on a semi- annual basis. The location of the groundwater samples collected during the semi-annual monitoring events is shown on the attached Figure 1. 2.1 Groundwater Monitoring Network There are four groundwater monitoring wells located at the facility that comprise the existing groundwater monitoring system (Figure 1). Monitoring well GMW-1 is located on the northeast corner of the landfill area and serves as the upgradient groundwater monitoring well providing background water quality. Monitoring well GMW-2 is located on the southwest side of the landfill and monitors hydraulically downgradient groundwater quality. Monitoring well GMW-3 is located on the western side of the landfill and monitors hydraulically downgradient groundwater quality. Monitoring well GMW-4 is located on the northwest side of the landfill and monitors hydraulically downgradient groundwater quality. Table 2 provides monitoring well construction information including installation date, well depth/screened interval, survey elevations, and lat/long for each well location. Table 3 provides the estimated hydraulic conductivity values for select monitoring wells based on falling/rising head slug tests. Westside C&D Facility Water Quality Monitoring Report April 2016 Page 6 3.0 Water Quality Sample Collection Samples of groundwater were collected in accordance with the approved Westside C&D 2010 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 2). 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. Westside C&D Facility Water Quality Monitoring Report April 2016 Page 7 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 is analyzed for volatile organic compounds only. 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 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. Westside C&D Facility Water Quality Monitoring Report April 2016 Page 8 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 compound tetrahydrofuran is included with the volatile organic analyses. 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. Westside C&D Facility Water Quality Monitoring Report April 2016 Page 9 5.0 Hydrogeological Conditions The depth to groundwater was measured in the four compliance monitoring wells during the April 19-20, 2016 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 2 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 west-southwest, toward the Toisnot Swamp Canal. Based on the results of prior hydrologic tests conducted at the site, the groundwater flow rate in the shallow saprolite ranges from 0.916 ft/day to 297.64 ft/day. The average hydraulic conductivity and transmissivity values for the site are provided on Table 3. Westside C&D Facility Water Quality Monitoring Report April 2016 Page 10 6.0 Laboratory Analytical Results Final laboratory analytical results for the samples collected on April 20, 2016 were received from the analytical laboratory on May 3, 2016. 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, only one volatile organic compound (VOCs) was detected at concentrations exceeding the Solid Waste Section Limits (SWSLs). The compound 1,2-dichloropropane was reported in monitoring well GMW-3 at a concentration of 2.3 ug/l. The established 2L Groundwater Standard for 1,2-dichloropropane is 0.6 ug/l. No other VOCs were reported in any of the monitoring wells above the laboratory detection limits, SWSLs, or 2L Groundwater Standards. The laboratory analyses did not report any concentrations of inorganic compounds above the 2L Groundwater Standards. The inorganic compound barium was reported above the laboratory detection limit and SWSL in monitoring wells GMW-1, GMW-3, and GMW- 4; however, the concentrations did not exceed the established 2L Groundwater Standard. Monitoring well GMW-3 reported a detectable concentration of beryllium; however, there is no established 2L Groundwater Standard for this compound. Monitoring wells GMW-2 and GMW-3 reported detectable concentrations of cobalt; however, there is no established 2L Groundwater Standard for this compound. Monitoring wells GMW-1, GMW-2, and GMW-3 reported detectable concentrations of zinc; however, the reported concentrations were well below the established 2L Groundwater Standard. A summary of the groundwater laboratory analytical results is provided on Table 1. Westside C&D Facility Water Quality Monitoring Report April 2016 Page 11 6.2 Quality Control Sample The laboratory supplied trip blank was broken during field sampling activities and as such could not be analyzed. The trip blank for the samples collected during the same monitoring event at the closed Wilson County Landfill did not detect any VOCs at a concentration equaling or exceeding laboratory quantitation limits. Westside C&D Facility Water Quality Monitoring Report April 2016 Page 12 7.0 Conclusions The results of this monitoring event report only minor variants from the established NC 2L Groundwater Standards. Based on the results of this water quality monitoring event, the Westside C&D facility will remain in Detection Monitoring in accordance with Title 15A NACA 13B .1600. The 2016 fall semi-annual water quality monitoring event is tentatively scheduled for October 2016.

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. Page 21 of 22
