Coca-Cola Enterprises -West <br /> USTEC Job No.90054.03 <br /> Each monitoring Nell was purged of at least three well volumes of water using a <br /> { deconkaminated Grundfos®purge pump. The specific pH,conductivity,and temperature were <br /> ;•monitored during the purge process. All water from the purging proce.,s was contained in <br /> { approved(DOT)17H,55-gallon steel drums. 'These drums were <br /> Depar►ment of Transportation <br /> i temporarily stored on-site pending completion of the analytical test results. Upon receipt of <br /> f <br /> r-- these results, the water from these drums was transported to Gibson Oil and Refining, Inc. of <br /> Redwood City, California for disposal. The transportation manifest for the purge water is <br /> presented in Appendix A. <br /> The groundwater samples were collected using a decontaminated 2-inch nominal diameter <br /> Teflon®bailer. Groundwater was discharged directly from the bailer into three 40-milliliter(ml) <br /> w, VOA glass vials with Teflon®septum caps and into one 1-liter amber glass bottle. The VOP.. <br /> vials were filled, copped, and inverted to check for passible air bubbles. IF air bubbles were <br /> 3 present, the vials were refilled and checked again. This procedure was repeated until an <br /> acceptable sample was obtained. The 1-liter containers were filled until there was no head space <br /> remaining in the bottle. A duplicate sample was collected From monitor well MW-3 and labeled <br /> t MW-7. An equipment blank was also collected by pouring distilled water through the Teflonm <br /> bailer after the final rinse and discharging directly into two 40-m1 VOA sample containers. A <br /> field blank was collected by pouring distilled water directly into two 40-ml VOA glass sample <br /> c <br /> containers. <br /> j t s <br /> All groundwater samples were labeled,wrapped in a protective wrap,double bagged in plastic <br /> bags and placed on ice and maintained at about 4° Centigrade to minimize potential <br /> �. volatilization of the organic compounds. Chain-of-custody documentation was maintained by <br /> USTEC persomad and accompanied the samples until delivery to Sequoia Analytical in Redwood <br /> y„ <br /> City, California. Sequoia Analytical is a California State certified ]..bnratory. The chin-of- <br /> t # custody documentation is presented in Appendix B. <br /> #y <br /> t• <br /> 4 <br />
