s <br /> KLEINFELDER <br /> EXPECT MORE <br /> A Kleinfelder, environmental geologist will be on site during the tank removal activities <br /> to collect soil samples for qualitative field screening and laboratory analysis. Tank <br /> excavation soil samples will be obtained by scraping the sidewalls or excavation bottom <br /> at the desired locations with the backhoe bucket. Samples will then be collected from <br /> the bucket by packing soil in a clean brass tube with a clean hand trowel. The soil <br /> samples may also be collected using a slide hammer lined with a clean brass tube with <br /> appropriate extension to reach the desired sampling depth. The collected brass tubes <br /> will then be sealed with Teflon sheets and tight fitting plastic caps. <br /> D-8.2 Collection of Water Samples and Laboratory Analysis <br /> If water is encountered in the excavation after the tank is removed, a representative <br /> sample will be collected for laboratory analysis. The tank excavation may be purged <br /> and allowed to refill before sampling. The water sample will be collected using a clean <br /> disposable bailer with new nylon cord. The bailer will be retrieved and the water will be <br /> contained in appropriate bottles supplied by the analytical laboratory for the requested <br /> analysis. <br /> In accordance with the Tri-Regional Guidelines one water sample will be collected from <br /> the tank excavation. The water sample will be delivered under chain-of-custody <br /> procedures to a state certified laboratory. <br /> 48093.E01/ST07R052/CJC/Iv Page D-8 <br /> ©2007 Kleinfelder, Inc January 26, 2007 <br />
