If the decline of the <br /> ground water level is not satisfactory within the first eight hours of the pilot test, additional testing <br /> will be performed to achieve sufficient ground water draw-down. <br /> The 12-hour pump test will be conducted at a constant rate determined by the results of the 8-hour <br /> pump test and the available storage or handling capacity for the produced ground water. Results of <br /> the 12-hour pilot test will be utilized to assess the feasibility of ground water extraction at the site. <br /> During the 12-hour pump test, three ground d water samplgs,�yill be collected from the effluent line <br /> at the initiation of the test, approximately 6 hours after pumping is initiated and just before the end <br /> of the pump test. The samples will be handled as described in Section 3.4. above and will be <br /> analyzed by a DHS-certified laboratory for the same constituents listed in Section 3.2. <br /> All extracted groundwater will be stored in a temporary, above-ground(Baker-type), storage tank. W'1 k <br /> Subsequently, the purged ground water will be transported to a suitable non-hazardous waste �f{+?A <br /> disposal/recycling facility. f <br /> 4.5. EQUIPMENT DECONTAMINATION <br /> All sampling tools used for sample collection will be thoroughly rinsed with clean water after being <br /> washed with a solution of Alconox.All down-hole drilling and sampling equipment will be pressure <br /> washed prior to starting each boring. <br /> Advanced GeoEnvironmental,Inc. <br />
