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 />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 on each proposed parcel must demonstrate a satisfactory <br />percolation rate. <br />Details and results of the percolation testing are summarized in the following table. <br />Table 2.

Satisfactory perc. <br />rate` <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 />1 Per San Joaquin County Environmental Health Department, a rate between 5.0 and 30.0 min/in requires an <br />8-foot separation between the bottom of dispersal system and ground water, or mitigation by system design <br />or enhancement. <br />2 Per San Joaquin County Environmental Health Department, a rate between 1.0 and 5.0 min/in requires a <br />20-foot separation between the bottom of dispersal system and ground water, or mitigation by system <br />design or enhancement. <br />Discussion of Percolation Test Results <br />The soils on each proposed parcel of the Site have demonstrated satisfactory <br />percolation rates for the use of septic systems in accordance with the requirements of <br />the San Joaquin County Environmental Health Department. The percolation tests are <br />considered representative of soils within a 100-foot radius of each test location. <br />LOGE 2121 Page 7
