rt <br /> w <br /> K <br /> a <br /> WaterWork <br /> Monitoring Well Develo ment Protocol <br /> ' Groundwater monitoring wells will be developed prior to setting <br /> the surface seal. Approximately 10 times the volume of water in <br /> the casing will be withdrawn if po-isible. Casing volumes will be <br /> calculated in the following manner: <br /> Volume of Schedule .40 PVC Pipe <br /> Diameter I.D.
