Discussion of Percolation Test Results <br />The soils within the proposed sewage disposal area of the Site have demonstrated a <br />satisfactory percolation rate for the use of a septic system in accordance with the <br />requirements of the San Joaquin County Environmental Health Department. <br />Because of the percolation rate between 5.0 and 30 min/in encountered in the test hole, <br />the San Joaquin County Environmental Health Department will require an eight-foot <br />separation from the bottom of the dispersal system to ground water, or mitigation by <br />system design or enhancement (see Table 2). Ground water is anticipated to be <br />encountered approximately 35 to 40 feet below ground surface at the Site; as a result, <br />no modification to standard shallow septic systems should be required. <br />Discussion of Septic System Sizing <br />Septic system construction utilizing leach lines or a filter bed should follow the San <br />Joaquin County On-Site Wastewater Treatment Systems Standards (2017) where <br />applicable. <br />LOGE 1924 Page 7
