LW �' �► <br /> L,, Chevron U.S.A. - Page 12 <br /> 10.0 RESULTS OF CHEMIICAL ANALYSIS <br /> v <br /> A total of 25 soil samples, and 3 ground water samples were submitted to a <br /> 60 State-approved laboratory for chemical analysis. Samples were analyzed to <br /> detect the presence and concentration of benzene, toluene, xylenes, total <br /> 1.0 petroleum hydrocarbons as referenced to diesel and gasoline, an selected soil <br /> samples analyzed for organic lead and ethylene dibromide (EDB) . The result of <br /> Lo <br /> those analyses have been summarized on Tables II and III as follows: <br /> La TABLE II <br /> Concentration of Petroleum Constituents in Soil <br /> (Concentration are expressed in parts per million <br /> Lo <br /> Sample I.D.
