<br /> ■ analyze samples obtained from two compliance wells (MW-215, MW-21D) and two nature-and-
<br /> extent wells (MW-23, MW-24) for the following constituents, as specified in the Underground
<br /> Injection Permit: carbon dioxide, chloride, manganese, mercury, potassium, volatile organic
<br /> compounds listed in NC-DEQ Appendix I
<br /> Analytical results will be incorporated into a report pertaining to a regularly scheduled compliance sampling
<br /> events.
<br /> Task R00592-
<br /> Groundwater Sampling Event 50 (Event 2018 S2)
<br /> DAA proposes to conduct groundwater sampling event 50 at the Orange County Regional Landfill — North
<br /> Facility during November, 2018.
<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-MW04, 6801-MW06R, 6801-MW07R,
<br /> 6801-MW14A, 6801-MW146, 6801-MW15, 6801-MW16, 6801-MW17, 6801-MW20, 6801-MW21 S,
<br /> 6801-MW21D, 6801-MW22) and two surface water locations for the constituents listed in 40 CFR
<br /> Part 258 Appendix 1 (15A NCAC 13B .1600), plus those constituents listed in Appendix 11 that have
<br /> been previously and reliably detected at this facility(mercury, naphthalene, sulfide)
<br /> ■ analyze samples obtained from two "nature and extent" monitoring wells (6801-MW23, 6801-
<br /> MW24), and analyzed for the constituents listed in 40 CFR Part 258 Appendix 1 (15A NCAC 1313 .1600),
<br /> plus those constituents listed in Appendix II that have been previously and reliably detected at this
<br /> facility (mercury, naphthalene, sulfide)
<br /> ■ analyze samples obtained from four additional wells (6801-MW21 S, 6801-MW21 D, 6801-MW23,
<br /> 6801-MW24) for chloride and carbon dioxide
<br /> ■ analyze samples obtained from four monitoring wells associated with the groundwater remediation
<br /> injection program (6801-MW21S, 6801-MW21D, 6801-MW23, 6801-MW24), and analyzed for the
<br /> following additional inorganic constituents, in accordance with the approved Underground Injection
<br /> Control permit: manganese, potassium
<br /> ■ analyze samples of surface water obtained from two locations along Old Field Creek, and analyzed
<br /> for the constituents listed in 40 CFR Part 258 Appendix I (15A NCAC 13B .1600), plus those
<br /> constituents listed in Appendix 11 that have been previously and reliably detected at this facility
<br /> (mercury, naphthalene, sulfide)
