ATC Associates Inc. <br /> Quality Assurance/Quality Control Plan <br /> Revised March 1998 <br /> 10.0 WELL DEVELOPMENT PROTOCOL <br /> Groundwater monitoring wells will be surged and developed prior to setting the surface seal. <br /> Approximately 10 times the volume of water in the casing will be withdrawn if possible. Casing <br /> volumes will be calculated in the following manner: <br /> ......... .... <br /> v-6 <br /> 4 <br /> A.

The volume of water produced versus time will be recorded. <br /> All withdrawn groundwater will be stored on-site in 55-gallon waste drums unless permission is <br /> granted by the appropriate regulatory agency to discharge the water to the ground surface or <br /> WAAdmin\ShcJls\QAQC-98.D0C <br /> 9 <br />
