The subject proposal is intended to encompass services that will be provided to conduct the Fall 2024 and Spring 2025 groundwater sampling/reporting events (July 2024 through June 2025). This proposal is restricted to services to be provided for the active C&D Landfill. Specific tasks to be performed during the service period are detailed as follows. Task-01 - Groundwater Sampling Event 39 (Event 2024 S2) TRC proposes to conduct groundwater sampling event 39 at the Orange County Regional Landfill – Active C&D Facility during November 2024. TRC shall coordinate field and laboratory services, obtain groundwater samples, review sampling documentation received from groundwater sampling personnel, chemically analyze groundwater samples (Eurofins), validate analytical data provided by the contracted laboratory, update historical summary tables, and prepare a report suitable for direct submission to NCDEQ. During the subject sampling event, the laboratory will analyze:  samples obtained from four compliance wells (6804-MW204S, 6804-MW209, 6804-MW210D, 6804-MW211R) for the constituents listed in Appendix I, one of the constituents listed in Appendix II (mercury), and several parameters that are unique to C&D facilities (manganese, iron, tetrahydrofuran, total dissolved solids, chloride, alkalinity, sulfate).  additional samples obtained from well 6804-MW-204S for quality control parameters (MS/MSD) Docusign Envelope ID: F9B80C56-CC66-4711-BEB6-35604883595F Mr. Bruce Woody July 9, 2024 Page 2  QA/QC samples (trip blank, duplicate, and field blank). TRC will prepare a digital version (Adobe Acrobat or functional equivalent) of the report and provide it to OCSWM and to NCDEQ. Additionally, all electronic data deliverables (EDDs) will be compiled and submitted to the State’s EQUIS database per NCDEQ requirements. Task-02 - Groundwater Sampling Event 40 (Event 2025 S1) TRC proposes to conduct groundwater sampling event 40 at the Orange County Regional Landfill – Active C&D Facility during May 2025. TRC shall coordinate field and laboratory services, obtain groundwater samples, review sampling documentation received from groundwater sampling personnel, chemically analyze groundwater samples (Eurofins), validate analytical data provided by the contracted laboratory, update historical summary tables, and prepare a report suitable for direct submission to NCDEQ. During the subject sampling event, the laboratory will analyze:  samples obtained from four compliance wells (6804-MW204S, 6804-MW209, 6804-MW210D, 6804-MW211R) for the constituents listed in Appendix I, one of the constituents listed in Appendix II (mercury), and several parameters that are unique to C&D facilities (manganese, iron, tetrahydrofuran, total dissolved solids, chloride, alkalinity, sulfate).  additional samples obtained from well 6804-MW204S for quality control parameters (MS/MSD).  QA/QC samples (trip blank, duplicate, and field blank). TRC will prepare a digital version (Adobe Acrobat or functional equivalent) of the report and provide it to OCSWM and to NCDEQ. Additionally, all EDDs will be compiled and submitted to the State’s EQUIS database per NCDEQ requirements. Task-03 – PFAS Sampling and Analysis – If Necessary A memorandum dated March 13, 2023, by North Carolina Department of Environmental Quality (NCDEQ) Division of Waste Management (DWM), Solid Waste Section (Section), stated that all groundwater, surface water, and leachate samples collected at solid waste sanitary landfills after July 1, 2023, are required to be analyzed for per- and polyfluorinated substances (PFAS). Per this requirement, PFAS sampling and analysis was completed at the Active C&D Landfill during the 2023 S2 and 2024 S1 sampling events. Results of the PFAS analysis were submitted to the NCDEQ under separate cover with the regularly submitted semi- annual monitoring reports. Upon review of the PFAS analysis results, the NCDEQ may require additional analysis for PFAS at select and/or all monitoring wells at the Active C&D facility. Accordingly, laboratory costs for additional PFAS analysis during the upcoming 2024 S2 and 2025 S1 sampling events is included as a separate line item until further direction from the NCDEQ.
