point on the well casing. Measurements were recorded on the data sheet in decimal <br /> feet. When necessary after measuring the water level, the deep hole was refilled with <br /> water to a level of six inches or more above the bottom of the hole. <br /> Percolation Test Results <br /> The completed percolation test form is included in Appendix 2 of this report. The form <br /> was signed by Ms. Kaur and indicates a percolation rate for each 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 greater than or equal to 1 minute per inch (min/in) but less than <br /> or equal to 60 min/in drop. A deep percolation test hole has a depth greater than 3.5 up <br /> to 25 feet; a satisfactory percolation rate for a deep test is greater than 1 min/in drop but <br /> less than or equal to 30 min/in. For the Site to utilize a standard septic system, one <br /> 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 testing are summarized in the following table. <br /> Table 2.

A satisfactory <br /> percolation rate for a"deep"test is less than or equal to 30 minutes per inch. <br /> `Only one test(shallow or deep) is required to pass per parcel for that parcel to utilize a standard septic system. <br /> Discussion of Percolation Test Results <br /> The soils within the proposed sewage disposal area of the Site have demonstrated a <br /> satisfactory percolation rate for the use of a standard septic system in accordance with <br /> the requirements of the San Joaquin County Environmental Health Department. <br /> LOGE 1848 Page 7 <br />
