well Development Protocol <br /> Groundwater monitoring wells will be developed by removing <br /> approximately 10 times the volume of water casing the Casing <br /> Or <br /> until relatively free of sand and silt, if possible. <br /> volumes will be calculated in the following manner: <br /> volume of Schedule 40 PVC Pipe <br /> Diameter 1.D.
