Percolation Test Procedure <br /> Live Oak conducted the percolation test for the boring on October 23, 2020. Due to <br /> initial percolation rates observed, a one-hour test was selected. Water level <br /> measurements were taken every 10 minutes during the one-hour period. The last 30 <br /> minutes of the test were observed by Daria Afonskaia, Registered Environmental Health <br /> Specialist at the San Joaquin County Environmental Health Department. <br /> An electronic well sounder with a depth accuracy of 1/100th foot was utilized for the <br /> water level measurements. The water level was measured against a fixed reference <br /> point on the well casing. Measurements were recorded on the data sheet in decimal <br /> feet. When necessary after measuring the water level, the hole was refilled with water <br /> 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 3 of this report. The form <br /> was signed by Ms. Afonskaia and indicates a percolation rate for the 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. A deep percolation test hole has a depth between 3.5 and <br /> 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 (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 /> LOGE 20-63 Page 7 <br />
