Groundwater samples collected on July 28, 1998,by Radian International,Inc.,and analyzed by Core Laboratories of Pasadena,California, <br /> and/or American Environmental Network of Pleasant Hill,California,and analyzed for TPHd,TPHmo,and TPHg using <br /> _l U.S.Environmental Protection Agency(EPA)Method 8015M;and for benzene,toluene,ethylbenzene,xylenes,and MtBE using <br /> 11 EPA Method 8020. Groundwater samples collected on November 5, 1998,by Geomatrix Consultants,Inc.(Geomatrix),and analyzed <br /> by Friedman and Bmya of Seattle,Washington,for TPHd using EPA Method 8015M. Sample extracts were prepared with a silica gel <br /> procedure(based on EPA Method 3630M)prior to TPHd analysis. Groundwater samples collected in May 2002 and August 2003 by Geomatrix <br /> and analyzed by Friedman and Bruya of Seattle,Washington,for TPHd and TPHg using EPA Method 8015M,and <br /> BTEX using EPA Method 8021B. Sample extracts were prepared with a silica gel procedure(based on EPA Method 3630M)prior to <br /> TPHd analysis. <br /> _1 5.
