Satisfactory perc. <br /> rate <br /> Shallow Test <br /> Note: A satisfactory percolation rate for a "shallow" test is greater than one min/in and less than or equal to 60 <br /> min/in. <br /> 1 Requires 8' separation between bottom of dispersal system and ground water, or mitigation by system <br /> design or enhancement, per San Joaquin County Environmental Health Department requirements. <br /> 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 standard septic system in accordance with <br /> the requirements of the San Joaquin County Environmental Health Department. <br /> Because of the percolation rate between 5.0 and 30 min/in, the San Joaquin County <br /> Environmental Health Department will require an eight-foot separation from the bottom ` <br /> of the dispersal system to ground water (see Table 2). Ground water is anticipated to <br /> be encountered from 200 to 240 feet below ground surface at the Site; consequently, no L� <br /> modifications to standard septic systems should be required. <br /> Discussion of Septic System Sizing <br /> Septic system construction utilizing leach lines and seepage pits should follow the San <br /> Joaquin County On-Site Wastewater Treatment Systems Standards (2017) where <br /> applicable. <br /> LOGE 1849 Page 7 <br />
