DocuSign Envelope ID: EFEF14CF-F5DA-421 F-81318-92CC412C35B3 1.0 INTRODUCTION Avery County is required to submit semi-annual groundwater monitoring reports for the Closed unlined MSW landfill (permit # 06-01) in accordance with Solid Waste Section Rule 15A NCAC 13B. This report, prepared by Smith Gardner, Inc (S+G), presents the semi-annual sampling for the event conducted on October 5, 2021. 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 mapping' 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 Smith + Gardner, Inc. (S+G) personnel performed this sampling event on October 5, 2021 in accordance with the approved Sampling and Analysis Plan. Samples were collected from three groundwater wells (MW-1, MW-2 and MW-3R) and two surface water locations (SW-1 and SW- 2). Sampling methods followed the protocol outlined in the North Carolina Water Quality Monitoring Guidance Document for Solid Waste Facilitiesz. 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. All groundwater samples were properly preserved, placed on ice, and transported to the laboratory facility within the specified hold times for each analysis. A map showing sampling locations is presented as Figure 1. Water table elevations and available construction details are presented in Table 1.

Field measurements are summarized in Table 2. 4.2 Laboratory Analysis Ground and surface water samples were transported to Waypoint Analytical, Inc. (Charlotte, NCI) 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. The additional compound, 1,4 Dioxane was analyzed via EPA Method 8260 SIM. Samples were transported under proper chain of custody. The laboratory report is included in Appendix A. 4.3 Laboratory Results Three inorganic constituents were detected at concentrations above their associated standards in samples collected this monitoring event. The inorganic constituents detected above associated standards include: • Cadmium (MW-1); • Cobalt (MW-1, MW-3R, and SW-2); and • Vanadium (MW-1). No organic constituents were detected at concentrations above their respective standards in samples collected this event. 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 1. 1449 Springbrook Road, Charlotte, NC 28217, NC DENR No.402. Avery County Closed MSW Landfill October 2021 Semi -Annual Report January 2022 Page 2 DocuSign Envelope ID: EFEF14CF-F5DA-421 F-81318-92CC412C35B3 6.0 CONCLUSIONS Laboratory results indicate the water quality at the Avery County Closed unlined MSW Landfill is generally consistent with historically reported results. Cobalt continues to be detected in groundwater samples at concentrations exceeding its standards. However, it should be noted that cobalt is also in exceedance in MW-3R, the site's background monitoring well. Given this and the low turbidity readings in all samples taken this event, cobalt can be inferred to be naturally occurring in North Carolina soils. S+G will continue to monitor all parameters. The next groundwater monitoring event is scheduled for Spring 2022. A report summarizing this event will be submitted to NCDEQ with laboratory analyses.
