PHS/EHD has the following comments <br /> regarding the recommendations contained in the report: <br /> 1. A groundwater investigation will be required due to the fact that <br /> i contamination in the pit has been documented down to 20 feet and San <br /> Joaquin County Flood Control Maps (August '86) document <br /> groundwater level at 20 feet. <br /> 2. It is recommended that the overexcavation of contaminated soil <br /> should continue until the pit is clean (4 sides and bottom). Borings <br /> should be considered on the perimeter of the excavation in order <br /> to define both the vertical and horizontal limits of contamination. <br /> 3. If it becomes necessary to abandon in place hydrocarbon contaminated <br /> soil, an estimate of the mass-volume of contaminated soil remaining in <br /> situ should be reported to PHS/EHD. <br /> A I)Msion of San Joaquin County Health rare bmv�= �� <br />
