<br /> Groundwater Sampling Event 52 (Event 2020 S1)
<br /> DAA proposes to conduct groundwater sampling event 52 at the Orange County Regional Landfill — South
<br /> Facility during May, 2020.
<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-MW110S, 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 /> tetra hydrofuran, total dissolved solids,alkalinity)
<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 field personnel to obtain leachate samples from
<br /> the South Facility, and chemically analyze the samples for the constituents listed in Appendix I, plus BOD,
<br /> COD, manganese, mercury, nitrate, sulfate, and phosphate.
<br /> DAA also plans to coordinate with field personnel to obtain groundwater samples from one residential well
<br /> (Ms. Nunn, 1621 Eubanks Road, Chapel Hill, NC 27516; identified as N1) for analysis of the constituents listed
<br /> in 40 CFR Part 258 (15A NCAC 13B .1600) Appendixl.
<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 R00592-2175-03
<br /> Environmental Compliance
<br /> DAA proposes to respond to "unanticipated" issues concerning environmental regulatory compliance that
<br /> may arise at South Landfill during the prescribed service period.
