(GeoAudit) have visited the property at <br /> 140 West Harding Way in Stockton,California to measure the depth to groundwater(Figure <br /> 1). <br /> On November 10, 1993, the depth to groundwater in the four monitoring wells on the site <br /> (Figure 2) was nieasured. The San Joaquin County Public Health Services - Environmental <br /> Health Division (PHS/EHD) was present to observe the measurements. Table 1 summarizes <br /> the results of the monitoring. No groundwater samples were collected. <br /> The depth to groundwater rose approximately 1/2 foot in each well between September and <br /> November 1993 (Table 1). Groundwater gradient was calculated to be 0.0032 ft/ft in a <br /> northeast dime etion (N 48' F; Figure 3). The results of this monitoring event are similar to <br /> those from the last 3 monitoring events (0.0020 to 0.0027 ft/ft, N 36° E to N 56° E). <br /> Sincerely, <br /> GEOLOGICAL AUDIT SERVICES, INC. <br /> Kevin McKibben Victor B.
