Fourth-Quarter 1996 Monitoring Report. Cargill Feed Product Facility at Port Road <br /> No. 8, Stockton, California; Sierra-Pacific Project No. 95-128.05 <br /> Dear Mr. Holm: <br /> Three monitoring wells were installed at the Port Road No. 8 facility on 10 October 1996. The wells were <br /> developed and surveyed on 15 October 1996. The wells were measured and sampled on 20 November 1996. <br /> The Fourth-Quarter 1996 Monitoring Report is enclosed for your review. Field observations and test results <br /> indicate the following: <br /> • Groundwater was flowing S 57' E with a gradient of 0.003 on 20 November 1996. Inflow from the <br /> nearby San Joaquin River apparently drives the flow of ground water at Port Road No. 8 and dictates <br /> the flow-direction. <br /> • N-NO3 and TKN concentrations detected in the shallow ground-water were relatively low, probably <br /> due in part to the natural flushing effect of inflow from the San Joaquin River. <br /> • Elevated bicarbonate, chlorine, and cation concentrations in ground water samples collected at the <br /> Port of Stockton appear to be derived from the intrusion of mineral-bearing (connate) ground-water. <br /> Please call if you have questions or directives. <br /> Sincerely, <br /> SIERRA-PACIFIC GROUNDWATER CONSULTANTS, INC. <br /> VStepxh_e�app, CEG-1133 <br /> Senior Engineering Geologist <br /> JSR/jb <br /> Enclosure <br /> C.
