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 Satisfactory <br /> 8/28/25 2.07 8.06 4 hr. <br /> Shallow Test perc. 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 30.0 min/in requires an <br /> 8-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 proposed septic disposal area for the new home have demonstrated <br /> a satisfactory percolation rate for the use of a standard septic system in accordance <br /> with the requirements of the San Joaquin County Environmental Health Department. <br /> The percolation test is considered representative of soils within a 100-foot radius of the <br /> test location. <br /> Discussion of Septic System Sizing <br /> Septic system construction should follow the San Joaquin County On-Site Wastewater <br /> Treatment Systems Standards (2017) where applicable. In this area, the San Joaquin <br /> County Environmental Health Department typically recommends that systems utilize <br /> leach lines with seepage pits. <br /> LOGE 2544 Page 7 <br />
