Following development but prior to pump installation, Contractor shall inspect the <br /> interior of the casing with down-hole video camera to verify that the casing has <br /> not collapsed and that grout has not intruded into the well. <br /> B. Contractor shall install the dedicated well pump in each groundwater monitoring <br /> well in accordance the manufacturer's specification in the presence of the <br /> Engineer. Contractor shall tie the lead wire and safety cable to the discharge <br /> tubing every five (5) feet with zip ties, or as approved by the Engineer. <br /> Contractor shall install the well cap and hang the pump in the well casing at the <br /> appropriate depth as determined by the Engineer. <br /> C. Contractor shall not install pump until well development is complete. <br /> D. Following pump installation and in coordination with the Engineer, the Contractor <br /> shall provide temporary power and perform start-up testing of the pump, including <br /> verification of operation and pumping rate. <br /> E. Following startup testing and in coordination with the Engineer, the Contractor <br /> shall operate the pump to allow the Engineer to collect water quality samples for <br /> laboratory analysis. Samples will be collected once the following criteria are met: <br /> North County G-15&G-16 San Joaquin County <br /> Groundwater Monitoring Well Specifications 11 Public Works Dept <br /> Solid Waste Division <br />
