(minutes/inch) (see notes) <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. A satisfactory percolation rate for a "deep" test is greater than 1 but less than or equal to 30 minutes <br />per 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 design <br />or enhancement. <br />2 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 />3 Only one percolation test boring (shallow or deep) is required to pass for the property to be approved for a <br />standard septic system. <br />Per San Joaquin County Environmental Health Department's definition, a shallow <br />percolation test hole has a depth between 24 and 42 inches; a satisfactory percolation <br />rate for a shallow test is greater than or equal to 1 minute per inch (min/in) but less than <br />or equal to 60 min/in drop. A deep percolation test hole has a depth between 3.5 and <br />25 feet; a satisfactory percolation rate for a deep test is greater than or equal to 1 min/in <br />but less than or equal to 30 min/in drop. For the Site to utilize a standard septic system, <br />one percolation test hole (shallow or deep) must demonstrate a satisfactory percolation <br />rate within the proposed septic system disposal field. <br />Details and results of the percolation testing are summarized in the following table. <br />Table 2.
