placed in the bottom of the open soil boring, followed by a 2.0 -inch diameter PVC pipe <br />with perforations on the bottom. Pea gravel was then used to backfill a few inches of <br />the annular space. <br />Live Oak presaturated the percolation test hole approximately 24 hours prior to the <br />percolation testing. The hole was filled with water to a height of 12 inches above the <br />bottom of the boring for the presaturation. On the day of testing, the hole was found to <br />be intact and dry. <br />Percolation Test Procedure <br />Live Oak conducted the percolation test for the boring on February 23, 2022. Due to <br />the initial percolation rate observed, a one-hour test was selected. Water level <br />measurements were taken every ten minutes during the one-hour period. The last 30 <br />minutes of the test were observed by Naseem Ahmed, Registered Environmental <br />Health 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 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. Ahmed and indicates a percolation rate for the 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 must demonstrate a satisfactory percolation rate within the proposed <br />septic system disposal field. <br />Details and results of the percolation testing are summarized in the following table. <br />LOGE 2213 Page 6 <br />
