PHS/EHD has prepared the following <br /> Thank you for submittal of the requested addendum. PHS/EHD agrees that <br /> approximately 1 ,000 cubic yards of hydrocarbon impacted soil remain in place and <br /> that soil not impacted would require removal in order to access all the impacted <br /> soil. The question which remains is how much soil excavation would be necessary <br /> to sufficiently reduce the mass of hydrocarbon impacted soil so that the residual <br /> mass would no longer contribute to groundwater contamination. <br /> It appears as if vapor extraction is the most cost effective soil remedial alternative. <br /> Long screened intervals increase the vertical component of vacuum influence at <br /> the expense of the horizontal component; as the volume of contaminated soil that <br /> requires remediation is re-evaluated, please also consider the proposed construction <br /> of the vapor extraction remediation well, VW1 . Continued monitoring of the affect <br /> on groundwater quality that the remediation system may have is appropriate. <br /> When providing conclusions and recommendations, with regard to groundwater <br /> quality, please consider the construction of the monitoring wells from which the <br /> data is obtained. <br /> The corrective action plan and its numerous amendments, after the bidding process <br /> is complete, should be submitted to the State Water Resources Control Board <br /> Cleanup Fund Unit for pre-approval. PHS/EHD understands that permitting through <br /> the San Joaquin County Building Department and the San Joaquin Valley Unified <br /> Air Pollution Control District will be initiated once a contractor has been selected. <br /> A Division of San joagUin County Health Care Services <br />
