and after development. The purged water will be monitored for <br /> conductivity, temperature, pH, and turbidity <br /> All purge water and rinsate will be stored in sealed 55-gallon drums <br /> pending the results of laboratory analyses. Each drum will be clearly <br /> labelled to mchcate its contents and boring number. If analytical <br /> results indicate that the water contains petroleum hydrocarbons in <br /> excess of regulatory action limits, they will be disposed of as <br /> hazardous waste or treated on-site. <br /> After the wells are constructed and developed, they will be surveyed <br /> for elevation and located by taping them from known landmarks. <br /> The elevations of the tops of the well casings will be the same <br /> elevation base which has been used during previous investigations at <br /> the West Weber Avenue sites. <br /> The wells will be sampled using a pre-cleaned Teflon® bailer. Water <br /> samples will be placed in containers provided by the laboratory <br /> Water samples will be labeled with a unique sample number, the <br /> project name and location, the date and time, and the sampler's <br /> initials. Samples will then be placed in Zip-Lock® type plastic bags, <br /> sealed, and placed in an iced cooler. Information noted on the label <br /> will be recorded on a chain-of-custody form_ After completion of <br /> drilling, the samples will be delivered under chain-of-custody to a <br /> California-certified laboratory. <br /> Sample Analysis <br /> Soil samples and ground water samples will be analyzed for the <br /> following constituents• <br /> • Total Petroleum Hydrocarbons as Gasoline (TPH-G) (EPA <br /> Method 8015-Modified), <br /> • Benzene, Toluene, Ethylbenzenes, and Xylenes (BTEX) (EPA <br /> Method 8020), <br /> • Total Lead (EPA Method 7421), <br /> • Organic Lead (DHS Method), and <br /> • Ethylenedibromide (EDB) (DHS Specified Method) <br /> 2-h <br />
