DAA will <br /> also prepare a digital version (Adobe Acrobat or functional equivalent) of the report and provide <br /> copies to OCSWM and to NC-DEQ. <br /> Task R00592-195S <br /> Groundwater Sampling Event 48 (Event 2018 S I) <br /> DAA proposes to conduct groundwater sampling event 48 at the Orange County Regional Landfill <br /> —South Facility during May, 2018. <br /> DAA shall coordinate field and laboratory services,obtain groundwater samples,review sampling <br /> documentation received from groundwater sampling personnel, chemically analyze groundwater <br /> samples (ENCO), validate analytical data provided by the contracted laboratory, update historical <br /> summary tables, and prepare a report suitable for direct submission to NC-DEQ. <br />
