a1 <br /> . SECTION 2 <br /> SOIL AND GROUND WATER INVESTIGATION <br /> .RESULTS <br /> This section presents a summary of the soil and ground water <br /> investigation results acquired during the performance of Phase I and <br /> Phase II Environmental Assessments of the site <br /> Phase I Environmental Site Assessment <br /> A Phase I Environmental Site Assessment was performed at the Heinz, <br /> Tracy site in August 1997 Results of the Phase I ESA indicated that two <br /> formerly used USTs were still present at the site The approximate <br /> locations of the USTs is depicted in Figure 2 Based on information gained <br /> from interviews with Heinz employees, it is believed that both tanks <br /> previously contained gasoline and that one tank was approximately 500 <br /> gallons in volume and the other was between 2,000 and 3,000 gallons in <br /> volume Both tanks were reportedly taken out of service in the 1960's and <br /> were subsequently filled with sand <br /> Phase II Environmental Site Assessment <br /> Based on the collective findings from the Phase I ESA, a Phase II ESA was <br /> performed in September 1997 to determine if any subsurface soil or <br /> ground water contamination was present in the vicinity of the USTs The <br /> Phase II ESA included collection and analysis of shallow soil and ground <br /> water grab samples near each of the USTs Results of the samples are <br /> presented in the paragraphs that follow <br /> Soil Investigation <br /> During the Phase II ESA, soil samples were collected from two Geoprobe <br /> boreholes at each of the two presumed former UST locations UST1 is <br /> located between a loading ramp on the west end of the production <br /> 2-1 <br />
