Well Development Protocol <br /> Groundwater monitoring wells will be surged developed prior to <br /> setting the surface seal. Approximately 10 times the volume of <br /> water in the casing will be withdrawn if possible. Casing <br /> volumes will be calculated in the following manner: <br /> Volume of Schedule 40 PVC Pipe <br /> Diameter I .D.

The volume <br /> of water produced versus time will be recorded. <br />
