Concentrations of <br /> gasoline ranged from, 4,900 to 38,000 ug/l. BTEX compound were detected in. both <br /> samples. The highest concentrations were consistently detected in sample 67713 collected <br /> '{ froin MW 2. Benzene was detected in this sample at 13,000 ug/1 and gasoline at 38,000 <br /> l : <br /> ug/l. <br /> - Soil Samples <br /> I <br /> t <br /> t Sample 6751.1 collected from B-10/MW-1 and sample 67521 collected ficm B-11/MW-2 <br /> were analyzed for purgeable TIPH as gasoline and BTEX compounds. Both samples were <br /> collected at a depth of 31 feet. The analytical results indicated relatively lmv- <br /> I`I concentrations of several BTEX compounds when compared to the concentration detected <br /> in the ground water. Benzene was detected in B-10 at 11 ug/kg. Xylenes were detected at <br /> 21 and 33 ug/kg in B-10 and B-11, respectively. Concentrations of gasoline were not <br /> k detected in either sample. <br /> ` 4,3 OFFSITE WELL LOCATION SURVEY <br /> The SJCEHO in letter dated December 18, 1990 requested that a well location survey be <br /> conducted to locate wells within 2,000 feet of the site which potentially may affected by <br /> E the plume of contaminated ground water beneath the Nomellini site. Kleinfelder reviewed <br /> the California Department of Water Resources (DWR) and conducted a ground survey to <br /> . locate wells not listed in the DWR files. Kleinfelder also attempted to review SJCEHD file <br /> k ^' of drilling permit applications, but they were not available for review. Eleven wells were <br /> located either in the agencies records or during the ground survey(Table 5). <br /> Fivy;;it estxc.wells and cme indusirial well are locate(!between 1,600 to 2,OM feet south of- <br /> ,.. <br /> thy,site Tbxee shallow monitoring wells and one well of unknown.purpose-are loczted <br /> i w t„dr•the si The well locations are summarized on Table 5 and are shown <br /> yrf,s. _ <br /> lea-the Intersection of.l��shin Street d.Nar ;Dnve a roxtm_a;e :800. tc ,Gl0 fee <br /> pi Tth es •to <br /> 'M relative to the site on Plate 7. <br /> F18-91-62 9 <br /> Copyright 1991 Kleinfelder, Inc. <br /> is <br /> t:: <br /> f <br /> st <br />
