When necessary after measuring the water level, the hole was refilled with water <br />to a level of approximately six inches above the bottom of the hole. <br />Percolation Test Results <br />The completed percolation test form is included in Appendix 3 of this report. The form <br />was signed by Mr. Ahmed 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 18 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. For the Site to utilize a standard septic system, one <br />percolation test hole must demonstrate a satisfactory percolation rate within the <br />proposed septic system disposal field. <br />Details and results of the percolation testing are summarized in the following table. <br />Table 2.

Satisfactory perc. <br />rate1 <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. <br /> <br /> <br />Discussion of Percolation Test Results <br />The soils near the proposed sewage disposal areas of the Site have demonstrated a <br />satisfactory percolation rate for the use of septic systems in accordance with the <br />requirements of the San Joaquin County Environmental Health Department. This <br />percolation test is considered representative of soils within a 100-foot radius of the test <br />location. <br />Discussion of Septic System Sizing <br />Septic system construction utilizing leach lines with seepage pits should follow the San <br />Joaquin County On-Site Wastewater Treatment Systems Standards (2017) where <br />applicable.
