*4/ <br /> B-8 TANK REMOVAL SAMPLING <br /> B-8.1 Collection of Soil Samples and Laboratory Analysis <br /> Soil and water samples will be collected during the tank removal operations in accordance with <br /> the current Leaking Underground Fuel Tank Field (LUFT) Manual and the Tri-Regional <br /> Guidelines issued by the California Regional Water Quality Control Board(RWQCB). <br /> A Kleinfelder, environmental geologist will be on site during the tank removal activities to <br /> collect soil samples for qualitative field screening and laboratory analysis. Tank excavation soil <br /> samples will be obtained by scraping the sidewalls or excavation bottom at the desired locations <br /> with the backhoe bucket. Samples will then be collected from the bucket by packing soil in a <br /> clean brass tube with a clean hand trowel. The soil samples may also be collected using a slide <br /> hammer lined with a clean brass tube with appropriate extension to reach the desired sampling <br /> depth. The collected brass tubes will then be sealed with Teflon sheets and tight fitting plastic <br /> caps. <br /> B-8.2 Collection of Water Samples and Laboratory Analysis <br /> If water is encountered in the excavation after the tank is removed, a representative sample will <br /> be collected for laboratory analysis. The tank excavation may be purged and allowed to refill <br /> before sampling. The water sample will be collected using a clean disposable bailer with new <br /> nylon cord. The bailer will be retrieved and the water will be contained in appropriate bottles <br /> supplied by the analytical laboratory for the requested analysis. <br /> In accordance with the Tri-Regional Guidelines one water sample will be collected from the tank <br /> excavation. The water sample will be delivered under chain-of-custody procedures to a state <br /> certified laboratory. <br /> l <br />
