IT CORPORATION <br /> 4585 Pacheco Blvd <br /> Martinez, CA 94553 <br /> CONTACT. Don Kubik, Jr. Project Number 190916 <br /> Four water samples were received by the laboratory on June 30, 1992. <br /> Analytical Methodology <br /> Samples were analyzed for benzene, toluene,ethylbenzene,and total xylenes by EPA method 8020 -Gas <br /> Chromatography/Photo>ton1zat10n detection. Analysis for Total Petroleum Hydrocarbons (gasoline and <br /> diesel were performed by EPA modified method 8015 -Gas Chromatography/Flame ionization detection. <br /> Quality Control <br /> Prior to sample analysis an nutial five point cahbration is performed for all methods On the day of <br /> sample analysts a check standard for each method is analyzed to evaluate instrument performance on that <br /> day Compound response must be within 15% of the initial calibration. <br /> Matrix spike and maty x spike duplicates are prepared and analyzed at a frequency of 1 per 20 samples. <br /> Reviewed and Approved. <br /> f � <br /> Kapne S Starr for <br /> Emanuel Hignutt, Jr. <br /> AaaLytical Project Manager <br /> American Council of independent Laboratories <br /> Intemational Association of Environmental Testing Laboratories <br /> American Association for Laboratory Accreditation <br /> IT Field Analytical Services,4585 Pacheco Boulevard,Martinez, CA 94553 661A 192 <br />
