• � iC <br /> l <br /> ' south of east toward the deepest closing contour of the cone <br /> of depression (Figures 4 , 5) . (The lowest closing contour <br /> ' of the cone is located Just northeast of the intersection <br /> of South Wilson Way and East Charter Way) . This <br /> ' ined by the influence of geology <br /> observation is partly expla <br /> ' on the direction of water movement . Figure 18 shows that <br /> there is more sand concentrated in this immediate direction <br /> ' than toward the southeast . This figure may also explain in <br /> o end portions of the lines on <br /> part the tendency of the tw <br /> ' Figure 17 to bunch in toward one another , since sand s <br /> ' concentrations are less here . However, the major control <br /> on the configuration of these quality lines is pumping <br /> ' pattern and quantity of water withdrawn. <br /> The geologic configuration of sediments in the G <br /> Stockton area is demonstrated on Figure 18 which shows the <br /> i <br /> ' amount of sand in the upper 500 feet of drill depth as <br /> determined from an analysis of drillers ' logs . The <br /> individual sand beds could be of any thickness . All the <br /> ' sand beds in the surface , to 500—foot drill depth, were <br /> added to arrive at the thicknesses in the control wells <br /> ' used for contouring. The contours indicate the amounts of <br /> sand expected at different points in the area of the map . <br /> ' This figure demonstrates that there is no basis for expecting <br /> ' a lithologic "barrier" . If one were present there would be <br /> no sand on one side comQared to significant amounts of sand <br /> ' on the other side . This premise is further supported by <br /> ' -112- <br />
