<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 three monitoring wells associated with the sanitary landfill (6801-
<br /> MW6R, 6801-MW7R, 6801-MW17), and analyzed for the constituents listed in 40 CFR Part 258
<br /> Appendix I (15A NCAC 13B .1600), plus those constituents listed in Appendix II that have been
<br /> previously and reliably detected at this facility(mercury, naphthalene, sulfide)
<br /> ■ analyze samples obtained from nine monitoring wells associated with the sanitary landfill (6801-
<br /> MW4, 6801-MW14A, 6801-MW14B, 6801-MW15, 6801-MW16, 6801-MW20, 6801-MW21 S, 6801-
<br /> MW21 D, 6801-MW22), and analyzed for the constituents listed in 40 CFR Part 258 Appendix II (15A
<br /> NCAC 13B .1600)
<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 13B.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-MW215, 6801-MW21 D, 6801-MW23,
<br /> 6801-MW24) for chloride and carbon dioxide
<br /> ■ samples shall be 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 II (15A NCAC 13B .1600)
<br /> ■ analyze additional samples obtained from well MW-04 for constituents required by regulations for
<br /> monitoring of C&D landfills (manganese, iron, chloride, sulfate, total dissolved solids, alkalinity)
<br /> ■ analyze additional samples obtained from well MW-04 for quality control parameters
<br /> ■ analyze one trip blank for quality control parameters
<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.
