<br /> ■ analyze additional samples obtained from well 6801-MW110S for constituents required by
<br /> regulations for monitoring of C&D landfills (manganese, iron, mercury, chloride, sulfate,
<br /> tetrahydrofuran, total dissolved solids, alkalinity) (well 6801-MW110S is associated with the
<br /> monitoring programs for both the active C&D landfill and South sanitary landfill)
<br /> ■ analyze samples obtained from well 6801-MW110D for total arsenic
<br /> ■ analyze additional samples obtained from well 6801-MW110S for quality control parameters
<br /> • analyze one trip blank for quality control parameters
<br /> In addition to the above tasks, DAA plans to coordinate with the field personnel to obtain leachate samples
<br /> from the South Facility, and chemically analyze the samples for the constituents listed in Appendix I, plus
<br /> BOD, COD, manganese, mercury, nitrate, sulfate, and phosphate.
<br /> DAA will prepare one printed copy of the report,which will be delivered to OCSWM. DAA will also prepare a
<br /> digital version (Adobe Acrobat or functional equivalent) of the report and provide it to OCSWM and to NC-
<br /> DEQ.
<br /> Task R00592-
<br /> Groundwater Sampling Event 50 (Event 2019 S1)
<br /> DAA proposes to conduct groundwater sampling event 50 at the Orange County Regional Landfill —South
<br /> Facility during May, 2079.
<br /> DAA shall coordinate field and laboratory services, obtain groundwater samples, review sampling
<br /> documentation received from groundwater sampling personnel, chemically analyze groundwater samples
<br /> (ENCO), validate analytical data provided by the contracted laboratory, update historical summary tables,
<br /> and prepare a report suitable for direct submission to NC-DEQ,
<br /> During the subject sampling event, the laboratory will:
<br /> ■ analyze samples obtained from twelve compliance wells (6801-MW101, 6801 MW102S, 6801-
<br /> MW102DR, 6801-MW103S, 6801-MW103D, 6801-MW104, 6801-MW105, 6801-MW106, 6801-
<br /> MW107, 6801-MW11OS, 6801-MW111, 6801-MW112)for the constituents listed in Appendix I
<br /> • analyze additional samples obtained from well 6801-MW110S for constituents required by
<br /> regulations for monitoring of C&D landfills (manganese, iron, mercury, chloride, sulfate,
<br /> tetrahydrofuran, total dissolved solids, alkalinity)
<br /> ■ analyze samples obtained from well 6801-MW11 OD for total arsenic
<br /> ■ analyze additional samples obtained from well 6801-MW110S for quality control parameters
<br /> ■ analyze one trip blank for quality control parameters
