�-� TL 489-0589-02 'Page 5 <br /> metamorphic and igneous rocks (United States Geological society, <br /> 1968) <br /> --' In the Lodi area, the sediments attain a thickness of <br /> approximately 10, 000 .- feet. The �deposits containing fresh <br /> i <br /> L . groundwater are largely unconsolidated silts and -sands comprising <br /> i <br /> 3 <br /> river channel, flood plain, and alluvial fan deposits of Pliocene <br /> to Recent age. <br /> a <br /> The hydrogeology in the general vicinity of the site consists <br /> C of a perched, unconfined water table aquifer. The shallow <br /> L unconfined aquifer is underlain by a weakly confined aquifer. <br /> rw Based on the Map .of Lines ' 'of Equal Depth to Water in Wells <br /> published by the San JoaquinCounty Flood Control.. and Water <br /> 3 <br /> L_ Conservation District for the Fall of 1988, -depth to. groundwater in <br /> 9 - the area is approximately 50 feet below site grade (BSG) and <br /> i <br /> groundwater flow direction is to the east. . However, shallow <br /> groundwater flow is variable depending on groundwater production <br /> L <br /> well pumping within the local vicinity.
