Percolation Test Results <br />The completed percolation test form is included in Appendix 3 of this report. The form <br />was signed by Mr. Garcia Ruiz and indicates a percolation rate for the 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 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. A deep percolation test hole has a depth between 42 inches <br />and 25 feet; a satisfactory percolation rate for a deep test is greater than or equal to 1 <br />minute per inch (min/in) but less than or equal to 30 min/in drop. For the Site to utilize a <br />standard septic system, one percolation test hole (shallow or deep) 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.

Satisfactory perc. <br />Deep Test 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. A satisfactory percolation rate for a "deep" test is greater than 1 but less than or equal to 30 minutes <br />per inch. <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 septic system 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 should follow the San Joaquin County On -Site Wastewater <br />Treatment Systems Standards (2017) where applicable. We understand that the septic <br />system repair will be designed by Mr. Wert of Environmental Enterprises, Inc. <br />LOGE 2218 Page 8 <br />
