After recovery, samples will be collected <br /> using a clean Teflon bailer and promptly decanted into 40 ml <br /> VOA vials and/or one liter amber bottles, as appropriate. <br /> Vials and/or bottles will be sealed with Teflon-lined screw <br /> caps, labeled and stored on ice for delivery to a state <br /> certified laboratory. The sampling bailer will be cleaned <br /> with soap and a clean water rinse between uses. <br /> Wells will be checked for free product and sheen (using an <br /> interface probe and/or paste tape) prior to development and <br /> sampling. <br /> Properly executed chain of custody documentation will accom- <br /> pany all samples. <br /> 8. Laborators,� Analyses: <br /> Water and selected soil samples will be analyzed by Sequoia <br /> Analytical Laboratory in either Concord or Redwood City, <br /> California, both state certified laboratories, for TPH as <br /> gasoline using EPA. method 5030 in conjunction with modified <br /> 8015, and BTX&E using EPA method 8020, as recommended by the <br /> RWQCB, and as specified in the Tri-regional guidelines. <br /> Analytical results will be presented in tabular form, showing <br /> sample depths, results and detection limits. <br /> The analytical results will be used to delineate the vertical <br /> and lateral extent of the contaminants in soil and ground <br /> water. <br /> 9. Hydrology' <br /> Ground water flow direction will be determined from the survey <br /> data and water table uepths from both the new and existing <br /> wells. The flow direction will be shown on the site Plan. <br /> 10. conclusions: <br /> Conclusions and results of Phase II will be described in a <br /> 'technical report. <br />
