• Percolation Test Results <br /> The completed percolation test forms are included in Appendix 3 of this report. The <br /> forms were signed by Mr. Ahmed and indicate the percolation rate for each hole based <br /> on the final water drop observed. <br /> Per San Joaquin County Environmental Health Department's definition, a shallow <br /> percolation test hole has a depth between 36 and 42 inches; a satisfactory percolation <br /> rate for a shallow test is greater than 1 minute per inch (min/in) drop but less than or <br /> equal to 60 min/in drop. A deep percolation test hole has a depth greater than 3.5 feet <br /> and up to 25 feet; a satisfactory percolation rate for a deep test is greater than 1 min/in <br /> drop but less than or equal to 30 min/in. For the Site to utilize a standard septic system, <br /> one percolation test (either a shallow or deep test) must demonstrate a satisfactory <br /> percolation rate within the proposed septic system disposal field. <br /> Details and results of the percolation tests are summarized in the following table. <br /> Table 2. Percolation Test Summary <br /> Test No., Percolation Percolation Test Duration Comments <br /> Date Tested Test Rate (see notes) <br /> Depth (ft.)

A satisfactory percolation rate for a"deep"test is greater than 1 min/in but less than or equal to 30 minutes <br /> per inch. Only one test(shallow or deep) is required to pass per parcel for that parcel to utilize a standard septic <br /> system. <br /> 1 Requires 20' separation between bottom of dispersal system and ground water, or mitigation by system <br /> design or enhancement. <br /> 2 Requires 8' separation between bottom of dispersal system and ground water, or mitigation by system <br /> design or enhancement. <br /> • <br /> LOGE 1809 Page 6 <br />
