KLEINFELDER <br />A-7 Surface Water Monitorin« <br />1. Prior to collecting surface water samples, the depth of water is estimated at a designated <br />location in the surface water body. <br />2. Surface water samples are collected directly from the stream or surface water using a <br />clean unpreserved plastic bottle, disposable bailer, bailer, coliwasa, DipstikTM, dipper, <br />peristaltic pump, etc., or by directly filling the sample containers. Sampling equipment <br />will either be disposable, ' dedicated or decontaminated in accordance with the above - <br />defined decontamination protocols. Care is taken not to disturb the stream bottom and <br />introduce sediment in the sample. The fluid is then poured into appropriate preserved or <br />unpreserved bottles for the requested analysis. <br />3. The sample is labeled and immediately stored in an iced cooler pending transport to the <br />analytical laboratory. 'flhe sample is logged on a chain -of -custody. <br />iA-8 TANK REMOVAL SAMPLING <br />A-8.1 Collection of Soil Samples and Laboratory Analvsis <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 CalilOnila Rc(,ional Water Quality Control Board (RWQCB). <br />A Kleinfelder, environmental (,eologist 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 vv -ill then be sealed with Teflon sheets and tight fitting plastic <br />caps. <br />20-3978-03.W36/2019766 Page A-9 <br />© 1999, Kleinfelder_ Inc September 9, 1999 <br />� � i <br />
