0 <br /> Percolation Test Results <br /> /The completed percolation test form is included in Appendix 3 of this report. The form <br /> was signed by Ms. Medina and indicates a percolation rate for the hole based on the <br /> 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 less than or equal to 60 minutes per inch (min/in) drop. A deep <br /> percolation test hole has a depth between 3.5 and 25 feet; a satisfactory percolation <br /> rate for a deep test is 30 min/in or less. For the Site to utilize a standard septic system, <br /> one percolation test must demonstrate a satisfactory percolation rate within the <br /> proposed septic system disposal field. <br /> Only a shallow percolation test was required. Details and results of the percolation test <br /> are summarized in the following table. <br /> Table 3.
