Compound(s)may be present at concentrations below the detection limit. <br /> NR = Analysis not requested. <br /> ' = Chromatogram does not match diesel standard. Early diesel range predominates. <br /> ANALYTICAL PROCEDURES <br /> B=—Benzene,toluene,ethylbenzene,and total xylene isomers(BTEX)are measured by extraction using EPA Method 5030 <br /> followed by analysis using EPA Method 80-0/602,which utilizes a gas chromatograph(GC)equipped with a photoionization detector <br /> (PID)and a flame-ionization detector(FID) in series. <br /> TPIIg—Total petroleum hydrocarbons as gasoline(low-to-medium boiling points)are measured by extraction using EPA Method 5030, <br /> followed by analysis using modified EPA Method 8015,which utilizes a GC equipped with an FID. <br /> TPlid--Total petroleum hydrocarbons as diesel (high boiling points)are measured by extraction using EPA Method 3550 for soils and <br /> EPA Method 3510 for water,followed by modified EPA Method 8015 with direct sample injection into a GC equipped with an FID. <br /> Aueust 13. 1992 <br /> Laboratory R presentative Date Reported <br /> RESNA ENVIRONMENTAL LABORATORY IS CERTII7ED BY THE STATE OF CALIFORNIA <br /> DEPARTMENT OF HEALTH SERVICES AS A HAZARDOUS WASTE TESTING IA130RATORY <br /> (Certification No. E1211) <br /> 42501 Albrae Street • Fremont, CA 94538 9 Phone: (510) 623-0775 • (800) 247-5223 * FAX: (510) 651-8754 <br />
