. The stainless steel tube will then be driven with a rubber mallet into the newly exposed <br /> soil surface and filled completely so that no headspace remains in the tube at either end. <br /> Immediately after filling, each end of the tube will be covered with aluminum foil and <br /> a plastic cap, and sealed with duct tape The samples will be labeled with the project <br /> name, time, date, sample identification number and sampler's initials, and placed in a <br /> plastic bag All samples will be stored on ice in a cooler chest while in transit to the <br /> laboratory Chain-of-Custody documentation will be maintained for all samples <br /> Because the depth to ground water is about ten feet bgs in the area of the USTs, it is <br /> anticipated that no soil samples will be collected below the removed USTs Because the <br /> excavation will be shored, the sidewalls will also not be accessible for sampling <br /> However, four soil borings have been drilled near the margins of the tank cavity during <br /> previous investigations at the Site, and soil samples from these boreholes have provided <br /> information on soil conditions near the USTs A water sample will be collected from the <br /> tank cavity excavation <br /> 53 Water Sampling in the Former Tank Cavity <br /> Roux will collect a sample of the standing water in the former UST excavation A <br /> disposable polyethylene bailer will be lowered into the standing water, filled and brought <br /> to the surface The water will be decanted from the bailer into two 40-milliliter volatile <br /> organic analysis (VOA) vials These VOA vials will be labeled and stored on ice in a <br /> cooler chest while in transit to the laboratory <br /> 5.4 Laboratory Analyses <br /> All soil and water samples collected during this investigation will be delivered for <br /> chemical analyses to Sequoia Analytical (Sequoia) of Concord, California, a California <br /> Department of Health Services certified laboratory <br /> 5 Doc #A259WO1 15 <br />
