s•; <br /> will be collected after purging; operations. Appr{�ximately three to four welt vt>lunles of <br /> water will be purged from the wells before sampling using a submersible pumg). During; <br /> purging the ground water will be monitored for pll, temperature, and conductivity <br /> and <br /> purging will continue until these parameters have stabilized. if floating, product is <br /> encountered in a well, the well will not be purged or sampled. <br /> Water developed and purged from the well will be stored in 55-gallon steel drum: <br /> approved for use by the Department of Transportation. <br /> The water samples will be collected using;a clean teflon bailer and transferred slowl <br /> and scaled in appropriate laboratory-cleaned glassware with Teflon-lined lids, labeled, an <br /> promptly placed in iced storage. Chain-of-Custody records will be initiated by the sarnpl( <br /> and will accimpany the samples to the laboratory. <br /> LABORATORY ANALYSES <br /> Selected soil and water sample, will be analyzed for total petroleum hydresarbo <br /> (TPH) as gasoline by the modified EPA Method 8015. The samples will be analyzed I <br /> the volatile hydrocarbon constituents benzene, toluene, ethylbenzene, and total xyle <br /> isomers(13TEX)by EPA Methods 8020 (soil) and 602(water). Laboratory detection lin <br /> will be stated on the laboratory report. This analytical work will be conducted b, <br /> laboratory certified by the State of California. Additionally, the soil sample showing <br /> 8 <br />
