Percolation Test Results <br /> The completed percolation test forms are included in Appendix 3 of this report. The <br /> forms were signed by Mr. Escotto and indicate a percolation rate for each hole based on <br /> 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 less than or equal to 60 minutes per inch (min/in) drop. For the <br /> Site to utilize a standard septic system, one percolation test must demonstrate a <br /> satisfactory percolation 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.
