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 min/in. A <br /> satisfactory percolation rate for a"deep"test is greater than 1 but less than or equal to 30 min/in. <br /> 1 Per San Joaquin County Environmental Health Department, a rate between 1.0 and 5.0 min/in requires a <br /> 20-foot separation between the bottom of dispersal system and ground water, or mitigation by system <br /> design or enhancement. <br /> 2 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 design <br /> or enhancement. <br /> Discussion of Percolation Test Results <br /> The soils in the proposed septic disposal areas of the Site have demonstrated <br /> satisfactory percolation rates for the use of standard septic systems in accordance with <br /> the requirements of the San Joaquin County Environmental Health Department. Each <br /> percolation test is considered representative of soils within an approximate 100-foot <br /> radius of the test location. <br /> Because of the percolation rate between 1.0 and 5.0 min/in encountered in the test <br /> holes on Parcels 1, 2, 3, 4, 5, 6, 9, and 10, the San Joaquin County Environmental <br /> Health Department will require a 20-foot separation from the bottom of the dispersal <br /> system to ground water, unless mitigated by system design or enhancement.
