WELL DEVELOPMENT <br /> Development of the proposed wells will consist of a combination of bailing with a stainless <br /> steel bailer to remove the major portion of fine-grained sediment from inside the well, <br /> surging to flush out or draw in sediment from the filter pack, and additional groundwater <br /> evacuation with a Waterra inertia pump to finish the removal of fine-grained sediment. <br /> Developmental purging activities will be continued until field parameters (pH, electrical <br /> conductivity, and temperature) have stabilized and purged water is visually sediment-free. <br /> 3.4. GROUNDWATER SAMPLING PROCEDURES <br /> Groundwater sample collection will be performed in accordance with AGE's standard <br /> monitoring and sampling procedures, which have been included as Appendix B. <br /> 3.5. EQUIPMENT DECONTAMINATION/WASTE MANAGEMENT <br /> All sampling tools will be thoroughly rinsed with clean water after being washed with a <br /> solution of Alconox. All down-hole drilling equipment will be pressure washed prior to <br /> starting each boring. Rinseate and soil cuttings generated during drilling and groundwater <br /> sampling activities will be containerized in properly labeled, Department of Transportation <br /> (DOT)-approved 55-gallon drums and stored on-site in an area lacking public access. <br /> Disposal alternatives will be evaluated based on the results of soil analysis. <br />
