INC <br /> clays and silts to a depth of approximately 100 feet below ground surface Gravel lenses <br /> were reported to be present at a depth of approximately 100 feet below ground surface in <br /> many of the Lodi municipal water supply well logs that were reviewed The depth of these <br /> gravel lenses implies that they are probably the second of the three channel deposits <br /> mapped by Shlemon (1971) <br /> Water elevation data obtained from the City of Lodi and from the San Joaquin County <br /> Department of Public Works indicate that the groundwater gradient is generally to the <br /> south but that it tends to fluctuate from the south-southwest to the south-southeast (Exhibit <br /> 4) The local gradient is probably dominated by the local municipal supply wells pumping <br /> activity and recharge from the Woodbridge River to the north of Lodi This is generally <br /> supported by the Brown and Caldwell (1988) Final Report on the DBCP study of the City <br /> of Lodi where a groundwater flow direction to the south-southwest is reported and related <br /> to the DBCP concentrations in the municipal water supply wells <br /> • During the course of the Hi Hopes investigation, static groundwater level was first <br /> observed at depths ranging from 80 feet and 76 feet below ground surface from two of the <br /> four groundwater supply wells located on the property (groundwater elevation of <br /> approximately 20 feet below sea level) These depths are consistent with the regional <br /> groundwater surface elevation of approximately 30 feet below sea level in 1995 depicted <br /> on Exhibit 4 <br /> Based on water level measurements of the City of Lodi municipal water supply wells, the <br /> groundwater levels in the Lodi area have dropped almost 13 feet since 1987, which <br /> indicates that more water has been removed from the aquifer than was recharged <br /> 08220010 011 26 <br />
