Disposal will be the responsibility of the client. If requested Kleinfelder can assist <br /> with disposal at an additional cost. <br /> Task 3 — Stockpile soil Sampling <br /> Kleinfelder is proposing to collect four discrete soil samples from the estimated 75 yards of soil <br /> reportedly excavated from a former UST excavation located at the site. The four soil samples <br /> will be collected at locations representing approximately equal volumes within the stockpile. The <br /> samples will be submitted to a state-certified laboratory. <br /> Soil sampling depths will range from approximately one to five feet bgs or sides of the soil <br /> stockpile. The shallow borings will be advanced using a pre-cleaned stainless steel auger. The <br /> samples will be collected by slide-hammering a stainless steel sampler containing a 2-inch <br /> diameter by 6-inch long stainless steel sleeve into the stockpile. The stainless steel tube will then <br /> be removed from the sampling device and will be sealed with Teflon° sheeting and tight-fitting <br /> plastic end caps. Sampling equipment will be decontaminated between sample locations with a <br /> LiquinoxO (laboratory-grade detergent) and water wash and a distilled water rinse. <br /> After collection, the samples will be labeled, logged on a c am-of-custody form and immediately <br /> stored in an iced cooler. The samples will be transport d under chain-of-custody control to <br /> Kleinfelder's office and then transported by courier in � sealed container to a state certified <br /> 02001PROP.ENV/ST03P327 Page 7 of 11 <br /> ©2003 Kleinfelder,Inc.
