TPHg=total petroleum hydrocarbons quantified as gasoline;TPHd=total petroleum hydrocarbons quantified as diesel; <br /> TPHmo=total petroleum hydrocarbons quantified as motor oil;M[BE=methyl ter-butyl ether; <=analyte was not detected above <br /> detection limit indicated;NA=not analyzed. <br /> 2. Designates monitoring well location and sample number. <br /> 3. Sample depth in feel below ground surface(bgs). <br /> 4. Groundwater samples collected on July 28, 1998,by Radian International,Inc.,and analyzed by Core Laboratories of Pasadena,California, <br /> p and/or American Environmental Network of Pleasant Hill,California,and analyzed for TPHd,TPHmo,and TPHg using <br /> U.S.Environmental Protection Agency(EPA)Method 8015M;and for benzene,toluene,ethylbenzene,xylenes,and MtBE using <br /> 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 Brays 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 /> 5. Sample analyzed without/and with silica-gel preparation procedure. <br /> 6. Sample is a blind duplicate collected from well MW-2. <br /> f:NROIECI\5000,�([I o00\501[-04A, <br />
