(MESCO) is pleased to present this Semi-Annual Water Quality Report with Corrective Action Update for spring 2017 at the active Construction and Demolition (C&D) Landfill and closed Unlined Sanitary Landfill. NCDEQ Solid Waste Rules 15ANCAC13B.1630 through .1637 requires that Greene County provide this report to the SWS on a semi-annual basis. This report documents the quality of the ground and surface waters during this monitoring event performed on March 9, 2017. A brief corrective action update and qualitative evaluation comparing current and historical data is also presented. Constituents detected in quantifiable concentrations above North Carolina Groundwater Standards (2L) were benzene and vinyl chloride in sample MW-4 which was collected within the compliance boundary. Background The Greene County Active Construction and Demolition (C&D) Landfill and Closed Unlined Sanitary Landfill is located off Fire Tower Road (SR 1239), Walstonburg, Greene County, North Carolina and operates under permit #40- 02. A topographic map showing the facility location is included as Figure 1. Prior to operating as a C&D landfill, the site operated as an approximate 13-acre unlined sanitary landfill which stopped receiving waste prior to January 1, 1998 in accordance with the Greene County Transition Plan. The C&D landfill is operating on a portion of the top of the MSW unit which are monitored together. Water quality has been monitored at this facility on at least a semi-annual basis since 1994. MESCO submitted an Assessment and Corrective Action (ACM) [DIN:8776] report dated August 30, 2007. MESCO then developed a Corrective Action Plan (CAP) which was revised on February 12, 2010 (CAP-Rev. 5) [DIN:9670] and subsequently approved on February 16, 2010 [DIN:671]. Groundwater remediation using monitored natural attenuation (MNA) was initiated on March 30, 2010 and has continued on a semi-annual basis ever since. A Corrective Action Evaluation Report (CAER) was submitted to the SWS on October 16, 2012 (DIN:17502) which was reviewed by the SWS and responded to on December 6, 2012 (DIN:17837). As specified within rule 15A NCAC 13B.1632(i), the SWS Environmental Monitoring Report Form, and SWS memorandums this report contains sampling procedures, field and laboratory results, corrective action update, groundwater and surface water characterization, and findings. Well construction summary table, sampling and analysis summary table, detections compared to Standards tables, a groundwater flow directions/rates table, potentiometric map, natural attenuation screening matrix score table, quality assurance/quality control data, and field/laboratory analytical data results are enclosed herein. Sampling Procedures Environment 1 (E1) of Greenville, NC, reportedly performed this monitoring event utilizing portable monitoring methodology in accordance with the approved Sampling & Analysis Plan (SAP) contained in the CAP-Rev.5. E1 reportedly collected groundwater samples from five downgradient groundwater monitoring wells (MW-4, MW-5, MW-6, MW-7 and MW-8), one background well (MW-1R) and surface water point (Downstream). Quality control measures included analysis of an equipment blank (EB), field blank (FB) and trip blank (TB). The surface water point upstream of the facility (Upstream) was reported to be dry. Surface water and groundwater monitoring locations are depicted on Figure 1 and Figure 2 respectively. A summary detailing the construction of the water monitoring wells is presented on Table 1. Static water levels in each well were measured electronically prior to purging. Samples were transported under C- O-C protocol and analyzed within the hold times specified for each method. Field Parameter Data E1 recorded the field parameters pH, specific conductance, temperature, turbidity, oxidation reduction potential (ORP) and dissolved oxygen (DO) which are presented in the laboratory analysis report in Appendix A. Laboratory Results E1 performed analysis of groundwater samples for the constituents listed in Appendix I of 40 CFR 258. Both total and dissolved metals listed in Appendix I of 40 CFR 258 were reported as requested by the SWS in the CAER response (DIN 17837). In addition, samples from MW-4 and background well MW-1, were analyzed for the full suite of MNA performance parameters as part of corrective action. MNA analysis was conducted for volatile fatty acids, methane, ethane, ethene, and dissolved hydrogen by Microseeps Inc. of Pittsburgh, PA. A sampling and analysis table summarizing the locations, constituents, and methods is presented on Table 2. Laboratory results and C-O-Cs are contained in Appendix A. Water samples were analyzed to the laboratory-established Method Detection Limits (MDL), which are at or below current Solid Waste Section Limits (SWSL). Table 3 summarizes constituents detected in groundwater and quality control samples compared to current SWSL, Groundwater Protection Standards (GWP), North Carolina Groundwater Standards (2L) and Maximum Contaminant Levels (MCL) also known as “Federal Primary Drinking Water Standards”. Table 4 summarizes all parameters detected in the surface water samples compared to current SWSL, North Carolina Surface Water Standards (2B) and MCL's. Quality Control Samples Chromium was detected in low non-quantifiable (“j” qualified) concentrations in the QC samples EB and FB. Since chromium was not detected in excess of a regulatory Standard, any lab or field induced artifact contamination is inconsequential. 2 Groundwater Samples Three metals were detected in estimated concentrations (j-qualified) above their respective NC 2L/GWP Standard in samples collected from four downgradient wells as summarized in the following table.

Surface Water Samples No constituents were detected in excess of applicable 2B Standard in the surface water sample collected downstream of the facility. Groundwater Characterization A single-day potentiometric map of the uppermost aquifer is presented on Figure 2, using ground water elevation data reported by E1 for this event. Reported groundwater elevations were all within their respective historically identified range. Groundwater flow direction and rates were calculated based on reported data and are included in Table 5. Estimated flow flow rates during this event, quantified through modified Darcy's equation, ranged from about 17 ft/yr (MW-7) to 344 ft/yr (MW-8) for a site-wide average of approximately 87 ft/yr. 3 Figures Topographic Map with Site Location FIGURE 1 Greene County Active C&D over Closed MSWLF QUADRANGLE LEGEND NOTE: Topographical map assembled from corresponding USGS 7.5-min. quadrangles of the subject region. 105 Landfill Road (SR1257) Walstonburg, NC Lat:35-31-29.7520 Long:-77-41-49.4325 Northing:648520.2533 Easting:2387660.4409 DOWNSTREAM UPSTREAM 3,334'0 MW-4Benzene - 2.4 ug /lVinyl Ch lor ide - 3.9 ug/lMarch 9, 2017BENZENE(FT AMSL) (FT BTOC) (FT AMSL)15A NCAC 2L Groundwater Quality Standard 1.00 0.03MW-1R 121.78 5.45116.33MW-4 117.89 17.02100.872.4 3.9MW-5 115.76 16.6999.07MW-6 117.41 8.68108.73MW-7 110.48 11.4799.01MW-8 111.36 10.30101.06Groundwater Elevations and VOCs Above 2L StandardsWELL IDTOP OF CASING ELEVATION DEPTH TO WATER GROUNDWATER POTENTIOMETRIC ELEVATIONVinyl Chloride(ug/L) (ug/L) Natural Attenuation Interpretation Score Screening Inadequate evidence for anaerobic biodegradation* of chlorinated organics 0 to 5 Protocol Limited evidence for anaerobic biodegradation* of chlorinated organics 6 to 14 Score:17 Adequate evidence for anaerobic biodegradation* of chlorinated organics 15 to 20 Strong evidence for anaerobic biodegradation* of chlorinated organics >20 Scroll to End of Table Concentration in PointsAnalysisMost Contam.
