' --- — ---- nLEI vFELGER <br /> �� <br /> File No. 20-1147-44 <br /> September 28, 1993 <br /> Soil samples will be recovered at near-surface and approximately every 5 feet for field <br /> screening and logging. Samples are collected by advancing the boring to a point immediately <br /> above the desired sampling depth and then driving a modified California sampler, lined with <br /> three brass tubes, into the undisturbed soil. The sampler is then removed from the bottom of <br /> the boring. The ends of the bottom (third) tube are covered with teflon and sealed with tight <br /> fitting plastic caps. <br /> Samples will be immediately labelled and placed in an iced sample container. At the end of <br /> the day, the samples are delivered to the analytical laboratory under chain-of-custody control. <br /> Drill cuttings will be placed in 55-gallon drums or wrapped in plastic and left on site for <br /> disposal by the site owner. If requested, Kleinfelder can coordinate disposal of soil and water <br /> after analytical results are available. <br /> Upon completion of the field activities and receipt and review of the analytical results, a report <br /> of findings will be prepared for the client. The report will present. <br /> • A description of field activities, observations, and protocols <br /> • Tabularized results of ground water monitoring and soil testing <br /> This letter summarizes the requested information.
