1 <br /> A, <br /> Well Devela me-nt 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 water in the f.-rasing will be withdrawn if possible. Casing <br /> volumes 'will be calculated in the following manner: <br /> � a=i <br /> E Volume of Schedule 40 PVC Pipe <br /> Diameter I.D.
