Box 97607 Raleigh, North Carolina 27624 (919) 792-3733 February 20, 2017 Submitted via Electronic Mail Ms. Jaclynne Drummond Compliance Hydrogeologist North Carolina Department of Environmental Quality Division of Waste Management - Solid Waste Section 2090 US Highway 70 Swannanoa, North Carolina 28778 Subject: Semi-Annual Monitoring Report BASF Former Industrial Landfill Facility Permit # 11-02 Enka, North Carolina Dear Ms. Drummond: ELM Site Solutions, Inc., on behalf of BASF Corporation, herein submits an electronic copy of the semi-annual sampling report for the above-referenced site. This letter report presents results of the semi-annual sampling activities conducted on October 13, 2016, which constitutes the second semi-annual sampling event for 2016. The approved groundwater monitoring network consists of MW-3, MW-4R, MW-5 and background well MW-6. The monitoring network also includes surface water sample locations SW-1 and DW-2 from Hominy Creek. In a letter dated November 4, 2010, the North Carolina Department of Environmental Quality (NCDEQ) – Solid Waste Section requested the collection of an additional surface water sample from a seep area in conjunction with the semi-annual groundwater sampling events for a minimum of five (5) years. Sampling results for the monitoring wells, surface water samples and surface seep (Seep-1) are discussed below. In addition to the groundwater samples outlined above, 10 landfill gas monitoring wells (LG-1 through LG-10) were installed at the site in May 2010. Landfill gas quarterly monitoring events were conducted on September 16, 2016 and December 30, 2016 during this reporting period. Gas monitoring results are also discussed below. A completed Environmental Monitoring Report Form follows this letter report. Ms. Jaclynne Drummond February 20, 2017 2 FIELD ACTIVITIES Field Investigation methods for this groundwater monitoring event were conducted in compliance with industry standards and the U.S. Environmental Protection Agency (EPA) Region IV Field Branch’s Quality System and Technical Procedures. Groundwater samples from the site were collected on October 13, 2016 using ‘low-flow’ techniques with either a peristaltic pump (MW-3, MW-4R and MW-5) or a Proactive stainless steel submersible Monsoon pump (MW-6). Water levels were measured at each well prior to sampling using a Testwell water level meter (Table 1). Groundwater elevations were used to construct potentiometric contours for this sampling event (Figure 1). Purging was accomplished by using a variable speed peristaltic or submersible pump with the pumping rate adjusted to equal the approximate recharge rate of the well. Indicator parameters of pH, temperature, specific conductance and turbidity were measured regularly during purging with Horiba U-52 water quality meter until the measured values stabilized. This ‘low-flow’ method targets the collection of groundwater samples that have the least total suspended solid count obtainable without filtering in the field, thus giving a more accurate indication of dissolved constituents present in the aquifer. Surface water samples were collected directly from Hominy Creek by filling pre-preserved laboratory sample containers. The seep sample (Seep-1) was collected from a 4-inch pipe located at the base of the seep area. Sample locations are shown on Figure 2. Water quality parameters for the monitoring wells, surface water locations and seep at the time of sampling are presented in Table 2. As noted above, 10 landfill gas monitoring wells were sampled on September 16, 2016 and December 30, 2016. Well locations are presented on Figure 3. Percent lower explosive limit (% LEL) measurements and other applicable parameters (i.e., % methane by volume, % oxygen and % carbon dioxide) were recorded at the landfill gas monitoring wells using a laboratory calibrated Landtec GEM 2000 instrument. Sample collection record sheets are provided in Appendix A. SAMPLING RESULTS Environmental Conservation Laboratories, Inc. in Cary, North Carolina analyzed the groundwater and surface water samples for Appendix I volatile organic compounds (VOCs) by EPA Method 8260B, Appendix I metals by EPA Methods 6010C/6020A, mercury by EPA Method 7470A, sulfate by EPA Method 300.0 and total dissolved solids by SM 2540C. The surface seep sample was analyzed for Appendix I VOCs. A copy of the analytical data is presented in Appendix B. For data analysis, groundwater monitoring well results were compared to 15A NCAC 2L Groundwater Standards, the regulatory basis established to determine groundwater quality. Surface water results were compared to 15A NCAC 2B Surface Water Standards. Monitoring wells had one or more analyte concentrations that exceeded their respective groundwater standards. No analyte concentrations detected in the surface water samples exceeded their respective standards. Detections are discussed below. Analytical results are summarized in Table 3. Chlorobenzene was the only organic constituent detected above laboratory method reporting limits during the October 2016 monitoring event. This compound was detected at a concentration of 1.2 Ms. Jaclynne Drummond February 20, 2017 3 micrograms per liter (ug/L) in monitoring well (MW-3) and its duplicate sample (DUP). This concentration does not exceed its respective 15A NCAC 2L Groundwater Standard of 50 ug/L. No other organic constituents were detected above laboratory method reporting limits in any of the groundwater or surface water samples during the October 2016 monitoring event. For inorganic constituents, barium, cobalt, nickel and sulfate were detected in groundwater monitoring wells and/or surface water samples. Only cobalt (MW-3 and MW-5) and sulfate (MW-5) were detected above their respective 15A NCAC 2L Groundwater Standard. No 15A NCAC 2B Surface Water Standard has been established for sulfate which was detected in samples SW-1 and DW-2. As noted above, quarterly landfill gas monitoring events were conducted on September 16, 2016 and December 30, 2016 for 10 landfill gas wells located near the waste boundary during the reporting period. All gas wells exhibited 0% LEL through the reporting period. Current and historical landfill gas sampling data are summarized in Table 4. The following summarizes results from this reporting period: • No organic constituents were detected above their respective 15A NCAC 2L Groundwater Standard. • Cobalt was detected in two (2) groundwater monitoring wells (MW-3 and MW-5) at concentrations that exceeded its 15A NCAC 2L Groundwater Standard of 1 ug/L. It should be noted that background soil samples were collected during the initial seep investigation (2010) to assess naturally occurring site conditions. Results from the study included detection of cobalt at a maximum concentration of 9.34 milligrams per kilogram (mg/Kg). The NCDEQ - Inactive Hazardous Sites Branch (IHSB) has established a soil cleanup level protective of groundwater for cobalt at 0.9 mg/Kg. Oxidation Reduction Potential (ORP) measurements in the two (2) monitoring wells listed above indicated the presence of a reducing environment potentially mobilizing background metals from soils. Some, if not all, of the cobalt detected during monitoring may be due to mobilization of background metals from soil. • Sulfate was detected in one (1) monitoring well (MW-5) at a concentration that exceeded its 15A NCAC 2L Groundwater Standard of 250 ug/L. The sample result was 340 ug/L and was analyzed at dilution. • No inorganic element concentrations detected in surface water (barium and sulfate) exceeded their respective 15A NCAC 2B Standards (where a standard has been established) during this monitoring event. Sulfate was detected in surface water but a 15A NCAC 2B standard has not been established for this constituent. • All gas wells exhibited 0% LEL through the reporting period, which is consistent with historical monitoring.
