Report on Soil and Ground-Water Evaluation - September 11, 1989 - <br /> Proposed ARCO Station, Woodbridge, California AGS 39044-1 <br /> These data are summarized in Table 3 and were used to calculate the relative elevation <br /> of the ground-water surface in each well, prepare a Ground-Water Gradient Map (Plate <br /> P-13), and evaluate the slope of the ground-water surface across the site. The <br /> calculations indicate that the average slope of the ground-water surface was in a <br /> southwesterly direction away from the nearby river at the time of the measurement - <br /> (June 22, 1989). The evaluated gradient was 0.02. <br /> 6; TABLE 3 <br /> GROUND-WATER SURFACE ELEVATIONS <br /> Proposed ARCO Station Site <br /> N.E.
