rt i <br />�• + Clays, silts, and organic carbon, components of soils found beneath the site, <br /> tend to hold hydrocarbon impact in place This phenomenon limits the <br /> fraction of soil bound hydrocarbons that may be removed by physical <br /> means <br /> 2.5 Exposure Pathway <br /> Since gasoline constituents have been detected in groundwater beneath the site, it is reason- <br /> able to expect groundwater flow to be the primary exposure pathway The most likely expo- <br /> sure point would be a downgradient water-supply well located near the site In 1989, EA <br /> conducted a survey through the DWR to determine the location of water-supply wells within a <br /> 1/2-mile radius of the site The closest well this survey identified was a domestic well located <br /> approximately 1,700 feet south (upgradient) of the Chevron station The closest downgradt- <br /> ent well identified was a well located approximately 1,900 feet northeast of the site Informa- <br /> tion on the use of this well was not available <br /> A well survey was conducted by EA in order to determine the location of wells within <br /> 112 mule of the site, the survey identified seven wells within this vicinity PACIFIC investi- <br /> gated the construction and use of these wells and the results are presented in Table 1 <br /> 3201337B/CAP_AMD DOC 8 November 30, 1995 <br />
