I <br /> ' In soil a total of 7 of the 12 samples collected during the n <br /> p g drilling contained detectable <br /> concentrations of gasoline hydrocarbons Vertically, the extent of impacted sod was not fully <br /> defined The lateral extent of impacted soil above 25 feet appeared to be mostly limited to the <br /> vicinity of the former LIST system The lateral extent of impacted soil below 25 feet appeared to <br /> be more extensive and undefined, probably due to lateral migration in groundwater The soil <br /> sample analytical results are summarized in Table 1 <br /> In groundwater, the samples collected from MW-1, MW-2 and MW-3 contained detectable <br /> i <br /> concentrations of gasoline hydrocarbons, including TPH-as-gasoline and benzene, toluene, <br /> ethylbenzene, xylenes (BTEX) The groundwater sample collected from MW-4 did not contain <br /> gasoline compounds MTBE, TPH-as-diesel and TPH-as-motor oil were not detected in any of <br /> the four groundwater samples Since the groundwater flow direction was calculated to be toward <br /> the east-southeast, the downgradient extent of impacted groundwater was not defined The <br /> groundwater analytical results are summarized in Table 2, and the well construction details and <br /> groundwater monitoring data are included in Table 3 <br /> For the area within 2,000 feet of the site, seven water well completion reports were on file at the <br /> California Department of Water Resources (DWR) None of these wells were found, during <br /> reconnaissance The entire site vicinity appeared to be connected to California Water Service, <br /> and none of its water supply wells existed within the site vicinity The site vicinity was almost <br /> entirely commercial property, and city and county government buildings The nearest school to <br /> the site appeared to be the Trinity Lutheran School at 444 American Street, approximately 1,800 <br /> feet northeast of the site No other schools, hospitals, or other potential sensitive receptors were <br /> observed in the site vicinity The nearest surface water body to the site was McLeod Lake at <br /> Weber Point, approximately 1,000 feet west of the site <br /> 7 <br />
