To investigate this <br /> contamination further, three exploratory trenches were dug and sampled between 6 and 7 feet bgs. <br /> Three soil samples were collected under PHS/EHD inspection, AT,, AZT,, AZT., and evidenced total <br /> petroleum hydrocarbons of up to 65 ppm. PHS/EHD has determined that no further investigation of <br /> petroleum hydrocarbons in Area A will be necessary, based on the limited extent of petroleum <br /> hydrocarbon soil contamination evidenced and that seasonal high depth to groundwater is 30 feet <br /> (1986). <br /> During the 1992 investigation of Area D, contamination was evidenced from total petroleum <br /> hydrocarbons of up to 97 ppm at 10 feet bgs (D-4) and from trichloroethene of up to 46 ppb at 2 feet <br /> bgs (D-3). To investigate this contamination further, three soil borings (D-6, D-7, and D-8) were drilled <br /> to a maximum depth of 16.5 feet bgs. Samples were collected at 5, 10 feet and 15 feet bgs. No <br /> contaminants were detected in the soil samples in Area D. PHS/EHD has determined that no further <br /> investigation of petroleum hydrocarbons in Area D will be necessary, based on the limited extent of <br /> petroleum hydrocarbon soil contamination evidenced and seasonal high depth to groundwater. <br /> During the 1992 investigation of the Concrete Tank Area, contamination was evidenced from total <br /> petroleum hydrocarbons of up to 41,000 ppm at 15 feet (T-1) and from 1,1 dichloroethane of up to <br /> 5.3 ppm at 15 feet (T-1). To investigate this contamination further three soil borings (T-4, T-6 and <br /> A13-3) were drilled to a maximum depth of approximately 45 feet bgs. Soil samples were collected at <br /> 15.5, 20.5 and 40.5 feet bgs for T-4, at 15.5 and 40.5 feet bgs for T-6 and at 20.5, 45.5 and 55.5 <br /> feet for AB-3. No petroleum hydrocarbon contamination was indicated; however, chlorinated solvent <br /> contamination was noted during the installation of T-4 (15.5 and 20.5 ft bgs) of T-6 (15.5 and 40.5 <br /> ft bgs) and of AS-3 (20.5 ft). <br /> A Division of San Joaquin County Health Care Services <br />
