GROUND WATER DESCRIPTION FOR THE GENERAL AREA <br /> The San Joaquin County Flood Control and Water Conservation District's Lines of Equal Depth to <br /> Ground Water Spring 1999 indicates the depth to ground water is 90 feet or greater. Ground water <br /> flow direction locally appears to be variable and considered beneficial use. <br /> Ground water was not encountered in the 42-inch percolation test hole on 28 May 2008. <br /> Based upon a review of well permit records at EHD by an AGE representative, the total depth of <br /> domestic water supply well was not known,but the on-site agricultural supply well is over 175 feet, <br /> based upon the recorded pump depth.Other wells in the general area had recorded depth of 218 feet <br /> bsg and 240 feet bsg. <br /> 4.2. GROUND WATER CONTAMINATION IN THE AREA OF THE SITE <br /> The immediately adjacent and outlying land use for the parcel is agricultural in nature. There are <br /> potential ground water contamination issues associated with agricultural uses and local septic <br /> systems.A review ofthe California Department of Toxics and Substance Control(DTSC)Envirostor <br /> Database did not reveal a contaminated site within two miles of the property; however the State <br /> Water Resources Control Board's GeoTracker database indicated two closed leaking fuel <br /> underground storage tank (LUST) sites within a two-mile radius of the site. Both site have been <br /> closed and are located more than one-mile from the subject parcel. <br /> 4.3. ON-SITE EXISTING WELL DESCRIPTION <br /> The date of installation and well specifications of the existing domestic water supply well is not <br /> known. A well installation permit was not available during record review at EHD. The well pump <br /> was reportedly repaired in 1976,but well specifications were not noted on the permit(Appendix B). r <br /> The date of installation of the existing agricultural supply well is also not known.A well installation <br /> permit was not available during record review at EHD. A new well pump was reportedly installed <br /> in 1997. The depth of the pump was reported to be set at 175 feet bsg with the first water reported <br /> to be at approximately 108 feet bsg. <br /> Advanced GeoEnviron mental,Inc. <br />
