CONTAMINANT DISTRIBUTION <br /> Soil samples were tested for paint thinner , total <br /> hydrocarbons, phosphates, and halogenated/aromatic volatile <br /> organics (EPA methods 8010/8020) . Water collected from <br /> boreholes prior to closing and bailed monitor/piezometer wells <br /> was tested for phosphates and, purgeable halocarbons and <br /> purgeable aromatics (EPA methods 601/602) . <br /> The investigation to date has not provided enough data to <br /> establish a "zero line" for contaminant distribution. Motor <br /> oil contamination was found in boring 3 soil samples obtained <br /> from 9 and 12 feet of total depth, respectively. Paint thinner <br /> was also found in the 12 foot sample . <br /> Both of the water samples taken out of boring 1 and 3 <br /> showed benzene, toluene and xylene contamination. Soil and <br /> water results for boring 2 reveal no contamination detectable <br /> by the tests run. <br /> Methylene chloride was detected in soil samples collected <br /> from both MWl and PW2 . Other contaminants were detected in <br /> minor amounts and are summarized in the laboratory data <br /> included at the end of this report. <br /> 9 <br />
