Martin County Landfill November 2015 Groundwater Monitoring Report January 2016 Page 1 1.0 INTRODUCTION The Martin County Landfill, currently operating under Solid Waste Permit # 59-01. The facility includes a closed, unlined MSW landfill and an active C&D landfill that are required to perform semi-annual groundwater monitoring under rule 15A NCAC 13B .0510 and .0544 respectively. This report presents the results from the groundwater monitoring event performed on November 16, 2015; and includes laboratory analyses, summary tables and laboratory analytical reports. 2.0 SITE GEOLOGY The Martin Co. Landfill is located off McCaskey Road near Williamston in the Coastal Plain physiographic province. According to the Geologic Map of North Carolina (1985) this area is underlain by the Yorktown Formation. The Yorktown Formation is characterized by fossiliferous clay with varying amounts of fine-grained sand, and bluish gray shell material commonly concentrated in lenses. 3.0 SAMPLING LOCATIONS Samples were collected from four groundwater monitoring wells (MW-1, MW-2, MW-3 and MW- 4) associated with the closed MSW landfill and from three groundwater monitoring wells (CDW- 2R, CDW-5 and CDW-6) for the active C&D landfill. Four surface water locations (SW-1, SW-2, SW-3 and CDSW-2) are monitored for the facility. SW-2 was not sampled this event because it was dry. MW-1 serves as the facility background well. Available well logs and related well construction information are presented in Appendix A. 4.0 SAMPLING PROCEDURES Environment 1 personnel conducted the monitoring network sampling event November 16, 2015. Reported sampling methods followed the protocol outlined in the North Carolina Water Quality Monitoring Guidance Document for Solid Waste Facilities (NCDENR, DWM) and the Site Groundwater Monitoring Plan1. The depth to water in each well was gauged to determine groundwater depth then purged three to five well volumes or until dry. Water table elevations included in Table 1. Samples were reportedly collected by Environment 1 personnel in laboratory prepared containers for the specified analytical procedures. Groundwater samples were properly preserved, placed on ice, and transported to the laboratory facility (Environment 1, Inc. Wastewater ID: 10), within the specified hold times for each analysis. 1 Water Quality Monitoring Plan, Martin County C&D Landfill, January 2012. Richardson Smith Gardner and Associates, Inc. Martin County Landfill November 2015 Groundwater Monitoring Report January 2016 Page 2 5.0 FIELD AND LABORATORY RESULTS 5.1 Field Results Field measurements for groundwater depth, pH, temperature and specific conductance were collected for each location sampled during this monitoring event. Results are generally consistent with previous monitoring events. Field measurements are included in Table 2. 5.2 Laboratory Analysis Samples were transported to the Environment 1 laboratory facility in Greenville, NC under proper chain of custody and analyzed for Appendix I constituents, including metals and VOCs using the SWS approved methods indicated on the laboratory report. The laboratory analytical report is included as Appendix B. 5.3 Laboratory Results Analytical results were compared to the NCDWM Solid Waste Section Quantitation Limits (SWSLs) 2, 15A NCAC 2L.0200 (2LStandard) and the EPA established Federal Maximum Contaminant Limits (MCL) for groundwater samples; and the 15A NCAC 2B Standard for Class C waters (2B Standards) for surface water samples. Most constituents were reported either below the method detection limit (MDL) or were laboratory identified ‘‘J-values’’ indicating an estimated or non-quantifiable value. 5.3.1 Inorganic Constituents Detected inorganic constituents are presented in Table 3. 5.3.1.1 MSW Landfill Arsenic in MW-4 was the only inorganic parameter detected above its 2L Standard this event. 5.3.1.2 C&D Landfill The inorganic parameters arsenic, total chromium, and lead were reported above their 2L Standards in the sample from CDW-2R. 5.3.2 Organic Constituents Detected organic parameters are presented in Table 4. 2 New Guidelines for Electronic Submittal of Environmental Monitoring Data Memo, NCDENR --- Solid Waste Section, October 27, 2006 Martin County Landfill November 2015 Groundwater Monitoring Report January 2016 Page 3 5.3.2.1 MSW Landfill Laboratory analysis for the MSW landfill this monitoring event indicated the organic constituent benzene was detected above its 2 L Standard in the sample collected from MW-4. Vinyl chloride was also reported about its 2L Standard in the sample collected from MW-2. 5.3.2.2 C&D Landfill Tetrahydrofuran was reported above the MDL in the samples from CDW- 2R and CDW-6. A 2L Standard has not been established for Tetrahydrofuran. No other organics were reported detected this event. 5.3.3 Surface Water Results No inorganic or organic parameters were reported at concentrations above their 2B Standards in facility surface water samples this event. 6.0 GROUNDWATER CHARACTERIZATION A potentiometric surface map was prepared from groundwater elevation data collected during this sampling event. The data indicates that groundwater is flowing generally to the north and east across most of the site. Hydraulic conductivity data is not available for these wells; therefore, groundwater velocities could not be calculated. The potentiometric surface map is provided as Figure 1. 7.0 CONCLUSIONS Results from this monitoring event indicate concentrations of arsenic, total chromium and lead were detected above the 2L Standard. These parameters are naturally occurring in North Carolina soils, and likely sample turbidity influenced results to be ‘‘biased high’’ due to these naturally occurring constituents. The organic constituents benzene and vinyl chloride were also detected in samples from the MSW landfill site at concentrations similar to previous sampling events. The next groundwater monitoring event is scheduled for May 2016. A report with laboratory analysis will be submitted to NCDENR in accordance with 15A NCAC 13B .0510 and .0544.
