IM KLEINFELDER <br /> . The resulting ground water elevations will be contoured to assess the direction of the <br /> ground water gradient at the time of sampling. This information can then be used to <br /> assess which wells represent upgradient and which wells represent downgradient ground <br /> water conditions <br /> Task 4 Collection of Ground Water Samples <br /> Kleinfelder will collect samples from the three wells at the site The wells will be <br /> purged, and samples will be collected as described in Attachment A, Section A-4 2 <br /> Task 5: Laboratory Analysis and Database Management <br /> Three soil samples from B-3, and two soil samples each from MW-1, 2 and 3 will be <br /> submitted under chain-of-custody to a laboratory certified by the State of California <br /> Department of Toxic Substances Control (DTSC) The nine soil samples will be <br /> analyzed for <br /> ► Extractable Total Petroleum Hydrocarbons (TPH) <br /> Purgeable TPH <br /> ► Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX) <br /> The three water samples will be submitted under chain-of-custody to Superior The <br /> water samples will be analyzed for: <br /> ► Extractable TPH <br /> ► Purgeable TPH <br /> ► BTEX <br /> ► EDB <br /> Lead <br /> The samples will be analyzed on a regular turnaround schedule, usually requiring <br /> 15 working days for completion. <br /> Task 6. Tank Removal <br /> Upon completion of the initial assessment, tanks T2 and T3 will be removed. <br /> Kleinfelder currently anticipates that soil remediation may be accomplished during the <br /> tank removal. The soil will be over-excavated and remediated, recycled, or disposed <br /> of at a proper facility <br /> Task 7 Report of Findings <br /> Upon completion of soil and ground water sampling, and receipt and review of <br /> analytical results, a report of findings will be prepared for client review The report <br /> will include <br /> . A description of field activities, observations, and protocols, <br /> Lithologic logs, <br /> FWP2-92-25 Page 3 of 4 24-220152-DOO <br /> Copynght 1992 Klemfelder, Inc <br />
