This report, prepared by Smith Gardner, Inc (S+G), presents the semi-annual sampling for the event conducted on October 10, 2017. The groundwater monitoring network for the closed unlined MSW landfill includes three groundwater monitoring wells and two surface water monitoring locations. This report includes field procedure summaries, laboratory analyses and groundwater characterization for the closed MSW facility. 2.0 SITE GEOLOGY The Avery County Closed MSW Landfill is located in the North Carolina Blue Ridge province, along the eastern limb of the Blue Ridge anticlinorium. Published geologic mapping1 places the site approximately twelve miles west of the Brevard Zone (measured perpendicular to strike), which is the boundary of the Blue Ridge Belt and the Piedmont. The principal geologic units mapped in the immediate vicinity of the site include a mix of metamorphosed sedimentary and igneous rocks – termed paragneiss and orthogneiss, respectively – interlayered with contemporaneous schist, phyllite, and marble, later injected with various granitic intrusions, including plutons, pegmatites, and hydrothermal veins. Regional metamorphic grades in the region include kyanite-grade (high grade) and retrograde chlorite-biotite metamorphism (low grade). 3.0 SAMPLING PROCEDURES S+G personnel performed this sampling event that involved collecting samples from three groundwater wells (MW-1, MW-2 and MW-3) and two surface water locations (SW-1 and SW-2). No boring logs for these monitoring wells could be located in a North Carolina Department of Environmental Quality (NCDEQ) file search. Sampling methods followed the protocol outlined in the North Carolina Water Quality Monitoring Guidance Document for Solid Waste Facilities2. The depth to water in each well was gauged prior to purging and sampling. Samples were collected using new factory sealed Teflon bailers and placed in laboratory prepared containers for the specified analytical procedures. Groundwater samples were properly preserved, placed on ice, and transported to the laboratory facility within the specified hold times for each analysis. 1 North Carolina Geologic Survey at http://www.geology.enr.state.nc.us 2 Solid Waste Section Guidelines for Groundwater, Soil, and Surface Water Sampling, NCDENR, DWM, SWS, Rev 4-08.

Water table elevations and available construction details are presented in Table 1. 4.0 FIELD AND LABORATORY DATA 4.1 Field Measurements Following purging, field parameters for temperature, pH, turbidity and specific conductance were measured and recorded at each sampling location. These results are summarized in Table 2. In general these measurements were consistent with data from previous events. 4.2 Laboratory Analysis Ground and surface water samples were transported to Prism Laboratories, Inc. (Charlotte, SC3) where they were analyzed for Appendix I metals and volatile organic compounds (VOC) via the SWS approved EPA Test Method presented in the laboratory report. Samples were transported under proper chain of custody. The laboratory report is included in Appendix A. 4.3 Laboratory Results No inorganic constituents were detected above their 2L Standard in samples collected this event. Cobalt (MW-1, MW-2 and MW-3) and vanadium (MW-1, MW-2 and MW-3) were detected at concentrations above their GWP standard in samples collected this event. No organic constituents were detected in collected samples, above their 2L Standard this event. No inorganic or organic constituents were detected in surface water samples above their 2B Standard for Class C Waters in samples collected this event. Vanadium was detected in both surface water samples (SW-1 and SW-2) at concentrations above the MDL however; no 2B Standard has been established for this parameter. Analytical results are presented in Table 3. 5.0 GROUNDWATER CHARACTERIZATION A potentiometric surface map was prepared from groundwater data collected this sampling event. The general groundwater flow is toward the southeast across the site toward Brushy Creek. Hydraulic conductivity data was not available for these wells so groundwater velocities could not be calculated. The potentiometric surface map is included as Figure 2. 3449 Springbrook Road, Charlotte, NC 28224, NC DENR No.402.

The next groundwater monitoring event is scheduled for April 2018. A report summarizing that event will be submitted to NCDEQ with laboratory analyses.
