I The soundings were converted using casing-top elevations previously established by RFA The elevation data were used to calculate the present ground-water flow direction and gradient by I the three-point method The local flow direction on November 30, 1995 was calculated at N87°E along a virtually flat gradient of 0 004 foot/foot (see the Ground-Water Gradient Map, Figure 3) The flow direction has shifted dust 4° to the north since August 11 when it was approximately S89°E along a gradient of 0 003 foot/foot Sounding and flow direction data are listed in Table 1 TABLE 1 Ground-Water Sounding Data Carmen Punta Property-Stockton Weil Sounding Depth to Casing-Top Water Table Flow Direct"0 ' Number Date Water Elevation Elevation Gradient(FC/Ft) (Ft) (Ft AMSL) (Ft BMSA.)
