k'q KLEINFELDER <br /> 2 The leachate elevation is then measured from a set location using a conductivity-based <br /> water-level meter The level is generally measured from a surveyed mark on the north <br />' nm of the casing <br /> 3 A leachate sample is then collected using a clean, disposable bailer <br /> 4 The sample is labeled and immediately stored in an iced cooler pending transport to the <br /> analytical laboratory The sample is logged on a chain-of-custody <br />' A-7 SURFACE WATER MONITORING <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, DlpstikTM, 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 <br />' 3 Care is taken not to disturb the stream bottom and introduce sediment in the sample The <br /> fluid is then poured into appropriate preserved or unpreserved bottles for the requested <br /> analysis <br /> 4 The sample is labeled and immediately stored in an iced cooler pending transport to the <br /> analytical laboratory The sample is logged on a chain-of-custody <br /> A-8 TANK REMOVAL SAMPLING <br /> A-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 Klemfelder, environmentaleolo st will be on site during the tank removal activities to <br /> g In g <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 /> 1 caps <br /> 28209 T03/ST04R1402/DH lv Page A-7 <br /> ©2004,Klemfelder,Inc October 20,2004 <br />
