This report provides background information, a description of field activities, data, summary and analysis of the laboratory analytical results from the groundwater and surface water monitoring sampling event performed in May 2017. 1 INTRODUCTION A-1 Sandrock, Inc. operates the Construction and Demolition Debris Landfill (C&D Landfill) located at Bishop Road (State Road 1116), south of the city of Greensboro, Guilford County, North Carolina. The location of the landfill is shown on Figure 1. This C&D Landfill became operational in April 2009. The baseline monitoring was conducted in November 2006. Based on review of previously prepared documentation, groundwater monitoring has been performed at the permitted landfill since October 2009. State and federal regulations applicable to landfills are enforced by the North Carolina Department of Environmental Quality (NCDEQ), Division of Waste Management (DWM), Solid Waste Section (SWS). The C&D Landfill is permitted by the DEQ DWM under Permit No. 41- 17, which requires semiannual monitoring of groundwater and surface water quality. This monitoring event is the second (2nd) semiannual monitoring event for year 2016 as required by the Permit to Operate issued by the NCDEQ DWM on December 6, 2013. This report provides an evaluation of surface water and groundwater quality for the C&D Landfill. Currently, the monitoring program network at the landfill consists of six (6) groundwater monitoring wells and four (4) on-site surface water sampling locations. There is one (1) up gradient, natural background well designated as MW-1, and five (5) down gradient compliance wells being designated as MW-2, MW-3, MW-4, MW-5, and MW-6. The surface water sample locations are SW-1, SW-2, SW-3, and SW-4. SW-1 is located at the northwest boundary of the site where Hickory Creek enters the facility. SW-2 is located along an unnamed tributary to Hickory Creek where it enters the east side of the landfill. SW-3 is located along an unnamed tributary to Hickory Creek where it enters the south side of the landfill. SW-4 is located downstream where Hickory Creek exits the southwest corner of the landfill. The locations of the monitoring wells and surface water points are showed on Figure 1. A -1 Sandrock C&D Landfill, Permit No.41-17 Water Quality Monitoring Report, May 2017 Sampling Event 2 2 FIELD ACTIVITIES On May 31, 2017, SCS Engineers, PC, (SCS) personnel collected groundwater samples from six (6) groundwater monitoring wells and four (4) surface water sampling locations at the C&D Landfill. One duplicate sample, designated as DUP, was also collected during this monitoring event from well MW-1. Collected samples were analyzed for constituents listed in Appendix I of the 40 Code of Federal Regulations (CFR) Part 258, mercury, iron, manganese, tetrahydrofuran, alkalinity, chloride, sulfate, and total dissolved solids (TDS). The groundwater and surface water samples were collected and handled in accordance with the sampling protocols included in the Water Quality Monitoring Plan prepared for the site, as well as the SWS Guidelines for Groundwater, Soil, and Surface Water Sampling. Groundwater was purged and samples were collected from the monitoring wells using bailing sampling procedures. Total well depth, condition of the casing, and the groundwater recharge rate were used to determine the purging and sample collection method employed at each monitoring well. Prior to groundwater sampling, each monitoring well was purged of a minimum of three well volumes of water. During purging, measurements were taken in the field of conductivity, pH, temperature, water levels, and turbidity. Measured field parameters and additional observations pertaining to the C&D Landfill sampling locations are provided in Attachment 1. All groundwater samples were placed into laboratory-supplied sample bottles by a technician wearing a new pair of nitrile gloves. Surface water samples were collected into sample containers by direct submersion in the creek and/or tributary. One round of surface water field parameters consisting of conductivity, pH, temperature, and turbidity, was measured and recorded at each sampling location prior to collecting the sample. Surface water samples were placed into laboratory-supplied sample containers by a technician wearing a new pair of nitrile gloves. All reusable sampling equipment was properly decontaminated between sampling locations. Disposable sampling equipment and material was discarded after each use. Following collection, each groundwater and surface water sample was immediately placed on ice in a sample cooler for shipment to Pace Analytical (Pace), a North Carolina certified laboratory located in Huntersville, North Carolina. Proper chain-of-custody documentation practices were followed during collection and transportation of each sample; the documentation was included in Attachment 2 of this report. Chain-of-custody provides details of the laboratory analyses requested and performed on the samples. The laboratory analytical report was provided in the Attachment 2 also. A -1 Sandrock C&D Landfill, Permit No.41-17 Water Quality Monitoring Report, May 2017 Sampling Event 3 3 GROUNDWATER LEVELS AND FLOW Groundwater levels were gauged in the monitoring wells on May 31, 2017. Depths to groundwater were measured using an electronic water level meter that was thoroughly decontaminated between wells. Depth-to-water measurements were taken after the wells were opened for a sufficient period of time to allow water levels to equilibrate with atmospheric pressure. Water level data and groundwater elevation data were summarized on Table 1. The depth to groundwater across the site measured relative to the top of the polyvinyl chloride (PVC) casing ranged from 2.88 feet (MW-3) to 29.16 feet (MW-1), consistent with site surface topography. Based on the water level data collected during this monitoring event, a Groundwater Surface Contour Map was prepared and is presented as Figure 1. The pattern of the water-table contours indicated that the horizontal component of shallow groundwater flow at the site generally varies from north to west, which is consistent with the site surface topography and drainage features. The hydraulic gradient of the water table, based on data from Figure 1, varied from approximately 0.011 to 0.072 at the site. The groundwater flow velocity calculated based on modified Darcy equation on Table 1 varied from 0.35 to 2.35 feet per year. The groundwater flow direction is primarily towards the western property boundary, with radial flow to the north and south, toward the unnamed tributaries. The calculated groundwater flow velocity and estimated values for hydraulic conductivity and porosity were included in Table 1. Please note that for all the monitoring wells, the estimated value for hydraulic conductivity came from individual well aquifer tests (David Garrett, 2002) and effective porosity in the shallow aquifer was published empirical value from Groundwater and Wells (Driscoll, 1986). A -1 Sandrock C&D Landfill, Permit No.41-17 Water Quality Monitoring Report, May 2017 Sampling Event 4 4 WATER QUALITY FINDINGS Concentrations of detected constituents in groundwater samples were compared to analyte-specific Solid Waste Section Limits (SWSLs) established by the SWS and the NCDEQ rule 15A NCAC 02L .0202 Groundwater Quality Standards (2L). Concentrations of detected constituents in surface water samples were compared to analyte-specific SWSLs and the 15A NCAC 2B.0211 surface water quality standards (2B) established for class C waters. If the reported concentration was less than the SWSL, the analytical result was qualified as estimated per DEQ requirement, and was flagged with a “J” qualifier. Table 2 presents summary of detected constituents only, in groundwater. Table 3 presents summary of detected constituents only, in surface water. In both tables, constituent analytical results that exceeded their associated 2L or 2B standards, where applicable, were shaded. Table 4 presents summary of historically detected constituents only, in the groundwater and/ or surface water samples collected at the C&D Landfill. A hard copy of the laboratory report from Pace Analytical Services, Inc. with a copy of the chain-of-custody form is included in Attachment 2. All laboratory analytical results and field parameter data for groundwater and surface water are included in an electronic data deliverable (EDD) format file specified by the SWS (available in electronic form only, see Attachment 3). Also Attachment 3 includes the Environmental Monitoring Reporting (EMR) Form required to be submitted by the SWS. 4.1 GROUNDWATER ANALYTICAL RESULTS The summary of constituents detected in the groundwater during the December 2016 semiannual water quality monitoring event is provided in the sections below. 4.1.1 VOLATILE ORGANIC COMPOUNDS (VOCS) VOCs were not detected in the groundwater samples collected from monitoring wells. 4.1.2 METALS Eight metals were reported present in the groundwater at concentrations above MDL.

A -1 Sandrock C&D Landfill, Permit No.41-17 Water Quality Monitoring Report, May 2017 Sampling Event 7 5 SUMMARY The results of the May 2017 groundwater and surface water quality monitoring event performed at the A-1 Sandrock C&D Landfill indicate that the overall water quality appears unchanged and the reported data are consistent and comparable to the results reported during previous semiannual sampling events. The results are summarized in more detail in the sections below. 5.1 VOCS DETECTION SUMMARY During the May 2017 monitoring event VOCs were not detected in the groundwater samples collected from monitoring wells and in any of the surface water samples collected. Historically, three VOCs (acetone, 2-butanone, and toluene) have been detected. Acetone was detected once (November 2010) and toluene was detected twice (October 2009 and April 2010). Neither constituent has been found in the groundwater or surface water since May 2011. 2- butanone was reported once during June 2016 event. The historical analytical data for previously detected VOCs were presented in Table 4. 5.2 METALS DETECTION SUMMARY Cobalt, iron, manganese, and vanadium were reported in the groundwater samples collected from one or more monitoring wells at concentrations in excess of the respective 2L Standard during this monitoring event. Cobalt was detected in excess of the 2L Standard in well and MW-5. Cobalt has been consistently present in well MW-5 above its 2L Standard and the detected concentration during this monitoring event was higher compared to the that reported during December 2016 monitoring event. Iron was reported above its 2L Standard in the groundwater samples collected from MW-1, MW-2, MW-4, MW-5, and MW-6. Iron was reported in MW-2, MW-4, and MW-6 at concentrations above 2L Standard during the last four monitoring events, in MW-1 and MW-5 periodically during the last four monitoring events, and historically it has been found in the groundwater from these wells. Manganese was reported in excess of the 2L standard in MW-1, MW-4, MW-5, and MW-6. In these wells, manganese has been consistently present at concentrations in excess of 2L Standard. The reported concentrations appeared higher in MW-1, MW-4 and MW-6, and lower in MW-5 compared to the December 2016 monitoring event results. Vanadium was reported in excess of the 2L Standard in wells MW-4 and MW-6. It was not detected in the groundwater samples collected from other wells. However, vanadium has been consistently detected and present at concentrations above its regulatory limit in the groundwater across the site. Two metals, copper and iron, were present at concentrations in excess of the 2B surface water quality standards. Iron was reported at the SW-3 surface water location. There were three A -1 Sandrock C&D Landfill, Permit No.41-17 Water Quality Monitoring Report, May 2017 Sampling Event 8 instances at SW-3 in the last four sampling events with iron reported at concentrations exceeding the 2B standard. Copper was reported in excess of 2B standard at the SW-3 sampling location. Copper has been consistently present at concentrations reported in excess of 2B standard at SW- 3. Metal concentrations in groundwater are often dependent on the turbidity or suspended particulates (from the aquifer formation) retrieved with the groundwater sample, as well as metals naturally occurring in the in-situ soil. The turbidity is a function of the sampling method, well construction, well development, depth to groundwater, and grain size/consolidation of the water-bearing zone. Since unfiltered samples are acidified in the field at the time of sample collection, metals contained within the particulates are dissolved into the water sample. Thus, the presence of turbidity in groundwater samples often results in elevated (false positive) analytical concentrations for metals. Therefore, the presence of elevated metal concentrations does not necessarily indicate a groundwater impact. Additionally, certain metals are considered naturally occurring within the in-situ soils and not caused by a release from the landfill. It is known that the landfill is located in a historic mining district, where mineralization by concentrated metals has occurred. Further monitoring will pay attention to any reported constituents. The historical analytical data for metals detected in the past were presented in Table 4. 5.3 INORGANIC AND FIELD PARAMETERS Alkalinity, chloride, sulfate, and total dissolved solids were reported in all groundwater and surface water samples collected during May 2017 monitoring event. The reported concentrations of all inorganics appeared consistent with historically reported data for these parameters. The results of the field-measured groundwater quality parameters indicated that the values measured in the collected samples were generally consistent compared to the existing data set. Turbidity was the highest in the monitoring well MW-1, likely due to an ongoing construction project Bishop Road bridge spanning Hickory Creek introducing additional particulate matter into the creek. The pH readings measured in all monitoring wells were outside the 2L standard pH range specified in the 15A NCAC 02L .0202[c] and continue to indicate acidic groundwater. The field parameters measured in the surface water samples were consistent with the values reported in the past. 5.4 CONCLUSIONS The results of the groundwater monitoring event showed the consistent presence of metals in the groundwater. There was no indication that the landfill is causing, or contributing to, any degradation of groundwater quality. Furthermore, no down gradient groundwater users have been present or anticipated; therefore there has been no indication of any risk to the public at this time. A -1 Sandrock C&D Landfill, Permit No.41-17 Water Quality Monitoring Report, May 2017 Sampling Event 9 The results of the surface water monitoring event indicated conditions consistent with historic field and analytical data reported, and did not demonstrate an impact on surface water quality due to landfill activities. At this time, no changes or other recommendations for the monitoring program are warranted. The next water quality monitoring event at the A-1 Sandrock C&D Landfill is scheduled for November 2017.
