feet. When necessary after measuring the water level, each 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. Suszycki and indicates a percolation rate for each hole based on the <br /> least 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 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.

The <br /> percolation tests are considered representative of soils within a 100-foot radius of each <br /> test location. <br /> LOGE 2111 Page 7 <br />
