Our comments on the Draft Plan can be found <br /> in the enclosed memorandum. <br /> The Draft Plan is acceptable provided that the objectives of the investigation <br /> and remediation are revised to include potential impacts to water quality from <br /> the waste disposal sites. It is our understanding that the wells in the vicinity <br /> of the excavation will be sampled and analyzed for potential waste constituents <br /> if the existing data is insufficient. <br /> Our overall comment on the Draft Plan is that the sampling and analyses appears <br /> to be more than we feel is needed and could be reduced to be more site specific. <br /> If you have any questions, please call me at (916)361-5670. <br /> CAMILLA WILLIAMS <br /> Engineering Geologist <br /> CKW:cw <br /> Enclosure <br /> cc: Mr. Michael Work, Environmental Protection Agency, Region IX, San Francisco <br /> Mr. Jim Pinasco, Department of Toxic Substances Control , Region 1 , <br /> Sacramento <br /> Ms. Dianne Hinson, Public Health Services of San Joaquin County, <br /> Environmental Health Department, Stockton <br /> Mr. Marshall Cloud, Defense Distribution Region West, Tracy, Tracy <br />
