Bladen County Closed MSW Landfill September 2016 Groundwater Monitoring Report November 2016 Page 1 1.0 INTRODUCTION The closed, unlined Bladen County Municipal Solid Waste (MSW) Landfill (Solid Waste Permit # 09-01) requires semi-annual groundwater monitoring as a condition of the water quality monitoring program. This report, prepared by Smith Gardner, Inc. (S+G), presents the September 21, 2016 monitoring event results. This event was performed in compliance with NC Solid Waste Regulations. As specified in rule 15A NCAC 13B .0544 the October 2006 Electronic Deliverables Memo1 and the November 5, 2014 Groundwater, Surface Water, Soil, Sediment, and Landfill Gas Electronic Document Submittal Memo2, this report includes a Solid Waste Section (SWS) Environmental Monitoring Report Form and field procedure and laboratory analyses summaries for the closed MSW site. A potentiometric surface map, summary tables and laboratory analytical report are also included. 2.0 SITE GEOLOGY The Bladen County MSW Landfill is located off Highway 87 just east of Elizabethtown in the Coastal Plain physiographic province. According to the Geologic Map of North Carolina (1985), this area is underlain by the Black Creek Formation, which is characterized by gray to black lignitic clay with thin beds of fine grained sands and thick lenses of cross-grained sand. 3.0 SAMPLING LOCATIONS The sampling event was reportedly performed by Environment 1, Inc. (Greenville, NC) personnel on September 21, 2016. The groundwater monitoring network for the MSW landfill includes seven groundwater monitoring wells (MW-1, MW-3, MW-4, MW-5A, MW-7, MW-8 and MW-9) and two surface water locations (SW-1 and SW-2). MW-1 serves as the background location. Figure 1 illustrates the sampling locations. 4.0 SAMPLING PROCEDURES Sampling methods followed the protocol outlined in the North Carolina Water Quality Monitoring Guidance Document for Solid Waste Facilities (Department of Environmental Quality (DEQ), Division of Waste Management (DWM)). The depth to water in each well was gauged prior to purging and sampling. The field parameters pH, specific conductivity and temperature were measured at each sampling location. Water table elevations are included in Table 1. 1 New Guidelines for Electronic Submittal of Environmental Monitoring Data Memo, NCDENR ā€“ Solid Waste Section, October 27, 2006 2 Groundwater, Surface Water, Soil, Sediment, and Landfill Gas Electronic Document Submittal, NCDENR ā€“ Solid Waste Section, November 5, 2014. Bladen County Closed MSW Landfill September 2016 Groundwater Monitoring Report November 2016 Page 2 Samples were collected by Environment 1, Inc. personnel in laboratory prepared containers. Groundwater samples were properly preserved, placed on ice and transported to the laboratory facility (Environment 1, Inc.), within the specified hold times for each analysis. 5.0 FIELD AND LABORATORY RESULTS 5.1 Field Parameter Results Temperature, pH, and specific conductance were measured in the field at the time of sampling. The field parameter results are summarized in Table 2 and have remained consistent with previously reported sampling events. 5.2 Laboratory Results Samples were transported to the laboratory facility under proper chain of custody and analyzed to the laboratory established Method Detection Limits (MDL) for each parameter. Groundwater sample analytical results were compared with the DWM Solid Waste Quantitation Limits (SWSLs) for Appendix I constituents, the North Carolina Administrative Code(NCAC) 2L.0200 2L Standard (2L) and the Federal Maximum Contamint Limit. Surface water sample analytical results were compared with the 15A NCAC 2B Standard (2B) for Class C waters. Table 3 summarizes the detected constituent list. Several constituents were detected above their MDL at concentrations below the SWSLs. These are listed as ā€œJā€ values on Table 3, indicating they are non-quantifiable values. The laboratory report is included as Appendix A. 5.2.1 Inorganic Constituent Results No inorganics were reported above their 2L Standard during the September 2016 monitoring event. 5.2.2 Organic Constituent Results Only vinyl chloride in the sample from MW-9 was reported at a concentration above its 2L Standard for this event. 5.2.3 Surface Water Results No quantifiable detections of inorganic or organic constituents were reported in samples from the surface water locations. Bladen County Closed MSW Landfill September 2016 Groundwater Monitoring Report November 2016 Page 3 6.0 GROUNDWATER CHARACTERIZATION A potentiometric map (Figure 1) for the uppermost aquifer, was prepared from the groundwater elevation data for this sampling event. The data indicates that groundwater is flowing generally north to northwest across most of the site. Hydraulic conductivity data is not available for these wells so groundwater velocities could not be calculated. 7.0 CONCLUSIONS The reported organic detections are consistent with historically reported detections at the site. Monitoring well MW-9 is located immediately adjacent to the waste at the site. Surface water sampling did not indicate contaminant migration. The next groundwater monitoring event is scheduled for March 2017. Following receipt of laboratory data a report will be prepared and submitted to NCDEQ and Bladen County.
