Additionally, all electronic data deliverables (EDDs) will be compiled and submitted <br />to the State’s EQUIS database per NCDEQ requirements. This action was previously covered under the <br />regulatory task. <br /> <br />Task-02 <br />Groundwater Sampling Event 38 (Event 2024 S1) <br /> <br />TRC proposes to conduct groundwater sampling event 38 at the Orange County Regional Landfill – Active <br />C&D Facility during May 2024. <br /> <br />TRC shall coordinate field and laboratory services, obtain groundwater samples, review sampling <br />documentation received from groundwater sampling personnel, chemically analyze groundwater samples <br />(Eurofins), validate analytical data provided by the contracted laboratory, update historical summary tables, <br />and prepare a report suitable for direct submission to NCDEQ. <br /> <br />During the subject sampling event, the laboratory will analyze: <br />▪ samples obtained from four compliance wells (6804-MW204S, 6804-MW209, 6804-MW210D, <br />6804-MW211R) for the constituents listed in Appendix I, one of the constituents listed in <br />Appendix II (mercury), and several parameters that are unique to C&D facilities (manganese, iron, <br />tetrahydrofuran, total dissolved solids, chloride, alkalinity, sulfate). <br />▪ all samples (4 monitoring wells) for full list of PFAS compounds (40 analytes) of EPA (draft) <br />method 1633 per NCDEQ requirements. <br />▪ additional samples obtained from well 6804-MW204S for quality control parameters (MS/MSD). <br />▪ one trip blank for quality control parameters and one duplicate, one field blank for PFAS. <br /> <br /> <br />DocuSign Envelope ID: C990D277-21FB-4C06-B4C9-915AC8E361A8
