• r <br /> Evaluation of Contamination January 3, 1989 <br /> Former Texaco Service Station, Manteca, California AGS 38053-1 <br /> 1 <br /> in each well and the slope of the potentiometric surface across <br /> the site. The results are listed in Table 3, <br /> TABLE 3 <br /> GROUND-WATER ELEVATION DIFFERENCES <br /> Former Texaco Service Station <br /> 941 East Yosemite Avenue <br /> Manteca, California <br /> i Monitoring Static Water Level <br /> Well mop of Casing Water Below <br /> Number (feet below datum) Level Datum <br /> MW-1 0.73 23.90 24.63 <br /> MW--2 1.22 23.44 24.66 <br /> MW--3 0.00 24.52 24.52 <br /> Measurements in feet, October 27, 1988 <br /> Static water level measured in feet below top of casing. <br /> Datum is arbitrary elevation corresponding to top of <br /> casing for well MW-3. <br /> These data were interpreted to construct a Ground-Water Poten- <br /> tiometric Surface Map (Plate P-11) . This information indicates <br /> that the slope of the ground-water surface at the time of <br /> measurement was to the northwest at 0.18--foot per 100 feet, This <br /> ground water gradient and flow direction are subject to changes <br /> due to seasonal fluctuations and the rate of ground-water pumping <br /> in the vicinity. <br /> 15 <br /> ,4�,a/ied GeoSyste�s <br />
