(GeoAudit) have visited the property at <br /> 140 West Harding Way in Stockton, California to measure the depth to groundwater(Figure <br /> 1)• <br /> .i On March 1, 1994, the depth to groundwater in the four monitoring wells on the site (Figure <br /> 2) was measured. Table 1 summarizes the results of the monitoring. No groundwater <br /> samples were collected. <br /> The depth to groundwater rose an average of 0.72 feet between January 31, 1994 and March <br /> 1, 1994, continuing the rise noted during each monitoring event since September 1993 <br /> (Table 1). Groundwater gradient was calculated to be 0.0033 ft/ft in a northeast direction <br /> (N 58° E; Figure 3), although it appears to flatten toward the southwest. The results of this <br /> monitoring event are very similar to those from the last monitoring event (0.0031 ft/ft, N 50° <br /> E). Groundwater flow direction has been consistently northeast since GeoAudit began <br /> monitoring this site in March 1993. <br /> Sincerely, <br /> GEOLOGICAL AUDIT SERVICES, INC. <br /> Kevin McKibben _ _ Agisd <br /> Staff Geologist <br /> gist #3489 <br /> c: (2) addressee <br /> • Mr. Michael Infurna, PHS/EHD <br /> q <br /> Full Spectrum Environmental Services• Hydrogeology <br />
