CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, the soil conditions examined near the proposed septic system drain field <br /> were found to be suitable for a standard deep septic system. A satisfactory soil <br /> percolation rate of 27.8 min/in was observed in the deep soil zone at the test location. <br /> The depth of ground water based on recent aquifer levels is approximately 96 to 100 <br /> feet below ground surface. The ground-water flow beneath the Site is to the east at a <br /> rate of approximately 9 to 11 feet per mile. San Joaquin County experienced its highest <br /> recent ground-water levels in spring of 1983 and 1999; depth to water was <br /> approximately 65 to 70 feet at these times. <br /> The domestic well on the Site is not connected to a power supply at this time; no water <br /> sample was collected. <br /> LOGE 20-10 Page 8 <br />
