�.AWAW..►.. <br />. Working to Restore Nature <br /> Evaluation of Groundwater Gradient <br /> The elevation of the top of each well casing was measured by RESNA using well MW-4 as <br /> the datum point. The U S G.S Quadrangle Map, Stockton West, California 1976, was used <br /> to evaluate the elevation of the ground surface around well MW-4 The tops of the <br /> monitoring and recovery wells were surveyed relative to mean sea level on September 9, <br /> 1992 The elevation of the well casing and the depth to groundwater measured in each <br /> monitoring well were combined to evaluate the relative elevation of the groundwater surface <br /> in each well and the slope of the groundwater surface across the site <br /> 1112jesc/3soc9-4 <br />
