S <br /> 5 <br /> bottles will be filled directly from the discharge line of the <br /> bladder pump or from the bailer, and will be filled to the brim. A <br /> Teflon-lined cap (septa) will be placed on the bottles, and the <br /> volatile organic analysts (VOA) bottles will be checked to determine <br /> -- that no air bubbles remain within. <br /> All water samples will be labeled and stored as described in the <br /> soil samples section above, and transported to the Eureka laboratory <br /> in Sacramento within 48 hours. <br /> Soil Boreholes <br /> Soil boreholes will be grouted with bentonite-cement slurry or <br /> neat cement from the bottom of the borehole to ground surface. <br /> Decontamination procedures <br /> To prevent cross-contamination, soil sampling equipment and all <br /> pump., bailers, and their related tubing will be washed with <br /> laboratory-grade detergent, rinsed with tap water, and rinsed with <br /> deionized water before sampling and development. <br /> Downhole drilling <br /> equipment and the development <br /> Pump will be steam-cleaned before and <br /> between use at each borehole. <br /> , <br /> Quality Assurance plan <br /> The procedures to be Followed in sample collection, identifica- <br /> tion, and handling at the AR <br /> } c0 site are described below. The <br /> analytical. quality assurance program is also discussed. <br /> Sample Collection and Handlin <br /> Proper collection and handling are essential. to ensure the <br /> quality of the sample. All samples will be collected by experienced <br /> field personnel The samples will be collected in sui <br /> containers which have been table- <br /> containers <br /> " laboratory.
