Harnett County Anderson Creek Landfill April 2016 Groundwater Monitoring Report June 2016 Page 1 1.0 INTRODUCTION The Harnett County Anderson Creek Landfill, located at 1086 Poplar Drive, Spring Lake, North Carolina, operates a C&D landfill under Solid Waste Permit #43-03 and a MSW transfer station under Solid Waste Permit #43-09T. A permit condition of 15A NCAC 13B.0500 (et. seq.) is submittal of semi-annual groundwater monitoring reports to NCDENR. The Harnett County Anderson Creek Facility has two closed unlined MSW landfill units located in the southeast portion of the site; closure was completed in 1994. Two closed C&D landfill units were closed in accordance with the current closure regulations. One located between the closed, unlined MSW landfill and the second to the west of the larger closed MSW unit. This report presents the results from the semi-annual monitoring event conducted April 27, 2016 and includes a field procedure summary, laboratory analyses, summary tables and graphs and groundwater characterization. 2.0 SITE HYDROGEOLOGY According to the 1985 North Carolina Geological Map the landfill is situated in the Coastal Plain Physiographic Province. The Dunn–Erwin area in Harnett County is underlain by the cretaceous age Middendorf formation that is primarily light gray sand, sandstone and mudstone which acts as a confining unit. The Middendorf formation was deposited in a deltaic system and varies from 15m to over 100m thick1. Groundwater depths generally range from just under 5 ft. to more than 30 ft. below ground surface (bgs) across the facility. Groundwater generally flows southwest towards the local wetland feature. There are minor seasonal variations in the flow pattern, but overall flow direction is consistent. 3.0 SAMPLING LOCATIONS The sampling event, performed by Smith Gardner, Inc. (S+G) personnel, utilized the groundwater monitoring network that includes four monitoring wells. MW-1, MW-2, MW-4 and MW-5 which monitor the closed MSW landfill, four monitoring wells (CDMW-2, CDMW-3, CDMW-5 and CDMW-6) which monitor the C&D landfill, three newly installed monitoring wells (CDMW-7, CDMW-8 and CDMW-9) also designed to monitor the C&D landfill, and two surface water locations (SW-1 and SW-2). MW-1 is used as the background well for the site due to its remote, up-gradient location. A trip blank was also analyzed for quality control. Figure 1 illustrates sampling locations. Available well logs for the groundwater monitoring wells are included in Appendix A. 1 Sohl, Norman F. and Owens, James P. “Cretaceous Stratigraphy of the Carolina Coastal Plain”. The Geology of the Carolinas. University of Tennessee Press, 1991. p191-220. Harnett County Anderson Creek Landfill April 2016 Groundwater Monitoring Report June 2016 Page 2 4.0 SAMPLING PROCEDURES Sampling methods followed the protocol outlined in the North Carolina Water Quality Monitoring Guidance Document for Solid Waste Facilities (DENR, DWM) and the approved site Water Quality Monitoring Plan2. Each well was gauged to determine groundwater depth and then purged three well volumes or until dry. Depth to groundwater is presented in Table 1. Samples were collected by S+G personnel in laboratory prepared containers for the specified analytical procedures. Groundwater samples and quality control blanks, were properly preserved, placed on ice and transported to the laboratory facility within the specified hold times for each analysis. 5.0 FIELD & LABORATORY RESULTS 5.1 Field Results Temperature, pH, turbidity and specific conductance were measured in the field at the time of sampling via direct read instruments. Several wells had high turbidity levelsin samples collected this event.. Increased turbidity has been known to bias-high inorganic sample results. The field parameter results are summarized in Table 2 and are generally consistent with historic sample results. 5.2 Laboratory Analysis Ground and surface water samples were transported to Environment 1, Inc. (Greenville, NC) a North Carolina certified laboratory (Wastewater ID: 10) for metals and Appendix I VOC analysis. C&D samples were also analyzed for alkalinity, sulfide, chloride, total dissolved residue and tetrahydrofuran. The laboratory report is presented as Appendix B. 5.3 Laboratory Results Analytical results were compared to Rule 15A NCAC 2L.0200 (2L Standard), SWS established Groundwater Protection (GWP) Limits and Federal Maximum Contaminant Limits (MCL). Surface water results were compared with the NCAC 2B Standard for Class C waters (2B Standards). Most constituents were either below the method detection limit (MDL) or were “J- values”. J-values are identified by the laboratory as “between the MDL and the SWSL”. 2 Groundwater Monitoring Plan for Construction and Demolition Expansion, Harnett County, Anderson Creek Landfill, prepared for C.T. Clayton, Sr., P.E., by GeoLogix, Revised September 2004. Harnett County Anderson Creek Landfill April 2016 Groundwater Monitoring Report June 2016 Page 3 Historic graphs are not included in this report because the detections in these wells do not have comparable historic data. 5.3.1 Inorganic Constituents Four inorganic constituents were reported at concentrations above their 2L Standard this event.  Chromium (CDMW-7 and CDMW-8);  Iron (CDMW-2, CDMW-3, CDMW-5, CDMW-6, CDMW-7, CDMW-8 and CDMW-9);  Lead (CDMW-8 and CDMW-9) and  Manganese (CDMW-8). Two inorganic constituents were reported at concentrations above their GWP Standards from samples collected this event.  Beryllium (CDMW-2, CDMW-3, CDMW-5 and CDMW-9) and  Vanadium (CDMW-8 and CDMW-9). The inorganic constituents detected are common metals native to North Carolina soils. Turbidity levels were high in the majority of sampled wells for this event; indicating additional presence of suspended solids in the samples, which is known to bias metals results high. The indicator parameters alkalinity, chloride, sulfate and total dissolved residue were measured for samples collected from C&D wells this event. No samples had detections above the 2L Standard for chloride or sulfate. Several samples had reportable concentrations for alkalinity and TDR; however they do not have established 2L Standards. Inorganic detections are summarized in Table 3. 5.3.2 Organic Constituents No organic results were detected at concentrations above their 2L Standard in samples collected this event. Organic detections are provided on Table 4. 5.3.3 Surface Water Results No inorganic or organic constituents were detected above 2B Standards in surface water samples this event. Harnett County Anderson Creek Landfill April 2016 Groundwater Monitoring Report June 2016 Page 4 6.0 GROUNDWATER CHARACTERIZATION A potentiometric surface map was prepared from groundwater data for this sampling event. The data indicates that groundwater is flowing generally southwest towards the wetlands and McLeod Creek. This is consistent with groundwater flow patterns previously reported for the site. The potentiometric surface map is included as Figure 1. Groundwater flow velocities during the sampling event were calculated using the equation: V = Ki/n where: K = hydraulic conductivity i = groundwater gradient n = porosity Calculated groundwater velocities were 0.043 cm/sec (MW-4) and 0.002 cm/sec (MW-5) for the MSW wells; C&D wells averaged 8.06x10-5 cm/sec. Flow velocities and calculated gradients are included in Table 5. 7.0 CONCLUSIONS High turbidity measurements and reported TDS concentrations indicate an excess of solids in the samples collected this event. Beryllium, chromium, iron, lead and vanadium are naturally occurring in the soils of North Carolina. The high sample turbidity can yield inorganic results that are “biased high”. VOC analytical results are similar to previous sampling events with no exceedances detected. The next groundwater monitoring event is scheduled for October 2016. A report with laboratory analysis will be submitted to NCDEQ in accordance with 15A NCAC 13B .0544.
