This includes auger rods and sampling devices. In addition, care will be taken to <br /> prevent samples and sampling equipment from coming into contact with potentially <br /> contaminating substances such as fugitive dust,tape, oil, engine exhaust, corroded surfaces, <br /> dirt, or any airborne source of contamination. A temporary decontamination station shall be <br /> set up at the Site to contain decontamination water. Decontamination water will be <br /> containerized in U.S. Department of Transportation("DOT") rated drums, or equivalent. <br /> Waste handling is discussed in Section 2.4. <br /> The following procedures will be used to decontaminate sampling equipment: <br /> . 1. New disposable gloves will be used for each decontamination procedure to prevent <br /> cross-contamination of equipment. <br /> 2. Reusable equipment will be scrubbed with brushes using a solution of AlconoxR <br /> and potable water. Equipment will be triple rinsed with potable water. <br /> 3. If the sampling device is not going to be used immediately, it will be wrapped in oil <br /> free aluminum foil with the shiny side out. Sampling equipment used to collect <br /> samples for organic analyses will not be allowed to come into direct contact with <br /> plastic. <br /> 4. Sampling equipment that is not readily decontaminated will be discarded after each <br /> use. Discarded decontamination solutions,will be accumulated and containerized <br /> in U.S. DOT rated drums, or equivalent, for further characterization and disposal. <br /> Soil samples will be collected in plastic sleeves, which will be sealed with Teflon sheets and <br /> end caps. Decontamination of soil sampling equipment is limited to the rods used advance <br /> the borehole and the sample drive head. <br /> 2.4 Waste Handling <br /> Investigation Derived Wastes ("IDW") such as: soil cuttings, excess sample material, <br /> decontamination rinsate, disposable personal protective equipment, and other waste solids <br /> and liquids will be properly stored in U.S. DOT approved drums,pending waste <br /> • William DePaoli Property 3 of 11 <br /> Sampling and Analysis Plan <br /> February 2012 <br />
