PHS/EHD agrees that re- <br /> excavation is an effective method of soil remediation. WHF estimated that <br /> approximately 2,000 cubic yards of contaminated soil will be removed. Groundwater <br /> which seeps into the excavation will be pumped into holding tanks, analyzed and then <br /> properly disposed. The work plan however, did not address the problem posed by the <br /> sewer Iine which is located in the area of the proposed re-excavation. <br /> Field screening during the re-excavation will be accomplished using a photo ionization <br /> detector. For confirmation sampling of the excavation, PHS/EHD recommends that <br /> samples be taken every 20 linear feet. A mobile state certified lab will be on site to <br /> analyze soil samples. Additionally, an off site laboratory will be used for confirmation <br /> analysis. <br /> Contaminated soil removed will be stockpiled and proposed to be treated by aeration. <br /> PHS/EHD recommends that the stockpiled soil be placed on and covered with plastic <br /> until a determination has been made by the San Joaquin Valley Unified Air Pollution <br /> Control District regarding permitting requirements. <br /> A Division of San Joaquin Counry Health Care Semces <br />
