h� K L E I N F E L D E R <br /> volume recovered is estimated. The fluid is then poured into appropriate preserved or <br /> unpreserved bottles of the requested analysis. <br /> 4. After the sample is collected, the lysimeter vacuum is reset to the manufacturer's <br /> recommended value. The lysimeter is also tested to evaluate potential leaks that may <br /> cause vacuum pressure loss. <br /> A-6 Leachate Monitoring <br /> 1. The leachate riser or wells are first opened and allowed to equilibrate with the <br /> atmosphere. <br /> I <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 /> rim 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, DipstikTM, dipper, <br /> peristaltid 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. 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 /> 12280.MON/20028394 Page A-7 <br /> 0 2002 Kleinfelder,Inc May 10,2002 <br />
