Bladen County Closed MSW Landfill September 2014 Groundwater Monitoring Report November 2014 Page 1 1.0 INTRODUCTION The Closed unlined Bladen County 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 4, 2014 monitoring event results. This event was performed in compliance with NC Solid Waste Regulations. As specified in rule 15A NCAC 13B .0544 and the November 5, 2014 Groundwater, Surface Water, Soil, Sediment, and Landfill Gas Electronic Document Submittal Memo, this report includes a Solid Waste Section (SWS) Environmental Monitoring Report Form, 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 Co. 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, Incorporated (Greenville, NC) personnel on September 4, 2014. 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 & MW-9) and two surface water locations (SW-1 & SW-2). MW-7 was unable to be accessed this event therefore it was not sampled. MW-1 serves as the background location. Figure 1 illustrates 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 (NCDENR, 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. Samples were 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.), within the specified hold times for each analysis. Bladen County Closed MSW Landfill September 2014 Groundwater Monitoring Report November 2014 Page 2 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 at the specified DWM Solid Waste Quantitation Limits (SWSLs)1 for Appendix I constituents. Water samples were analyzed to the laboratory established Method Detection Limits (MDL). The laboratory report is included as Appendix A. Table 3 summarizes the detected constituent list. Several constituents were detected above the method detection limit at concentrations below the SWSLs. These are listed as ‘‘J’’ values on Table 3, indicating they are non-quantifiable values. 5.2.1 Inorganic Constituent Results This event barium (MW-1, MW-5A and MW-9) and selenium (MW-9) were detected above their SWSL. No inorganics were reported above the NCAC 2L.0200 2L Standard (2L). 5.2.2 Organic Constituent Results Only vinly chloride in MW-9 was reported at a concentration above its SWSL and 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. 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. 1 New Guidelines for Electronic Submittal of Environmental Monitoring Data Memo, NCDENR – Solid Waste Section, October 27, 2006 Bladen County Closed MSW Landfill September 2014 Groundwater Monitoring Report November 2014 Page 3 7.0 CONCLUSIONS The reported barium and selenium concentrations are likely due to natural deposit erosion and suspended solids in the sample. The reported organic detections are consistent with historically reported detections in MW-9. 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 2015. Following receipt of laboratory data a report will be prepared and submitted to NCDENR and Bladen County.
