k <br /> 4.4 Samle Analysis <br /> P y <br /> Samples collected were taken to a California certified laboratory at the end of <br /> the day. The soil samples were analyzed for!�gasoline according to modified <br /> EPA Method 8015. This method quantifies gasoline compounds by a solvent <br /> !� extraction of hydrocarbons from the soil matrix, <br /> ix, injection of the solvent into <br /> x the capillary column of a gas chromatograph; and flame ionization detection <br /> Cof hydrocarbons. Method 8020 will be used for analysis of BTEX. <br /> 4.5 Detection limits for the Analyses <br /> The detection limit for metals in soils is as follows: <br /> Detection <br /> Method Analyte Limit <br /> L Mod 8015 Gasoline 5.0 mg/kg f <br /> I 8020 Benzene 3 gg/kg <br /> 8020 Ethyl Benzene 3 gg/kg <br /> 8020 Toluene 3 gg/�kg <br /> 8020 Xylene 3 gg/kg <br /> - If <br /> I <br /> I} <br /> 1 <br /> Work Plan Addendum Page 4 <br /> Custom Food Machinery <br /> i July r, 1993 <br />
