GENESIS ENGINEERING&REDEVELOPMENT <br /> 2.3.2 Sampling Equipment Decontamination <br /> The following procedures will be used to decontaminate sampling equipment: <br /> 1. New disposable gloves will be used for each decontamination procedure to <br /> prevent cross-contamination of equipment. <br /> 2. Equipment will be scrubbed with brushes using a solution of AlconoxTM and <br /> 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 <br /> in oil free aluminum foil with the shiny side out. Sampling equipment used to <br /> collect samples for organic analyses will not be allowed to come into direct <br /> contact with plastic. <br /> 4. Sampling equipment that is not readily decontaminated will be discarded after <br /> each use. Discarded decontamination solutions,will be accumulated and <br /> containerized in U.S. DOT rated drums, or equivalent, for further <br /> characterization and disposal. <br /> Groundwater sampling will be performed using new disposable equipment(i.e.,bailer, etc.); <br /> therefore, decontamination of groundwater sampling equipment is limited to the rod used to <br /> deliver the bailer to the groundwater interface. The rod will be decontaminated as discussed <br /> above for the soil sampling equipment. <br /> 2.3.3 Field Instrument Decontamination <br /> The following procedure will be used to decontaminate groundwater field parameter testing <br /> equipment and organic vapor analyzers: <br /> 1. Equipment, or portions of equipment,which are water resistant will be <br /> scrubbed with a solution of AlconoxTm and distilled water. Equipment will be <br /> rinsed with potable water followed by a rinse with distilled water. <br /> 2. Equipment, or portions of equipment,which are not water resistant will be TM <br /> repeatedly wiped with a paper towel moistened with a solution of Alconox <br /> and distilled water until clean. <br /> 3. Discarded decontamination solutions will be accumulated and containerized in <br /> U.S. DOT rated drums, or equivalent, for further characterization and <br /> disposal. <br /> William DePaoli Property 5 of 15 <br /> Sampling and Analysis Plan <br /> June 2009 <br />
