Table 2. Percolation Test Summary <br /> Test No., Percolation Test Percolation Rate Test Duration Comments <br /> Date Tested Depth (ft.) (minutes/inch) (see notes) <br /> P1-S, <br /> 9/22/2021 2.49 5.95 1 hr. Satisfactory perc. <br /> Shallow Test rate <br /> Note: A satisfactory percolation rate for a "shallow" test is greater than 1 but less than or equal to 60 minutes per <br /> inch- <br /> 1 Per San Joaquin County Environmental Health Department, a rate between 5.0 and 30 min/in requires an <br /> eight-foot separation between the bottom of dispersal system and ground water, or mitigation by system <br /> design or enhancement. <br /> Discussion of Percolation Test Results <br /> The soils near the existing 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. This <br /> percolation test is considered representative of soils within a 100-foot radius of the test <br /> location. <br /> Because of the percolation rate between 5.0 and 30 min/in encountered in the shallow <br /> test hole, the San Joaquin County Environmental Health Department will require an <br /> eight-foot separation from the bottom of the dispersal system to ground water. Ground <br /> water is anticipated to be encountered approximately 24 to 29 feet below ground <br /> surface at the Site; consequently, no modifications to standard septic systems should <br /> 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. No new construction is proposed. <br /> LOGE 2151 Page 8 <br />
