PHS/EHD has prepared the following <br /> comments for your consideration. <br /> Soil contamination is'-suspected to have developed as a result of the storage of leaking. <br /> machinery. Five soil-samples were collected at depths ranging from 6 to 12 inches below <br /> ground surface. Soil contamination was evidenced up to 1,700 ppm Total Recoverable <br /> Petroleum Hydrocarbons. Based on seasonal high depth to groundwater for the area of less <br /> than 10 feet (1986 San'7oaquin County Flood Control) additional investigation to determine <br /> the vertical and horizontal extent of contamination will be necessary. PHS/EHD concurs <br /> with the recommendation to include more qualitative laboratory analyses during additional <br /> investigation. <br /> Please submit a work plan by August 31, 1993 to continue the investigation. Copies of all <br /> reports, work plans or correspondence should also be forwarded to the Central Valley <br /> Regional Water Quality Control Board.
