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 a four-hour percolation test for the boring on November 12, 2019. <br /> Water level measurements were taken every 30 minutes during this four-hour period. <br /> The last 30 minutes of the test were observed by Sukhreet Kaur, Registered <br /> Environmental Health Specialist at the San Joaquin County Environmental Health <br /> 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. Kaur and indicates a percolation rate for the hole based on the least <br /> water drop observed during the test period, as required by San Joaquin County <br /> Environmental Health Department policy (personal communication with Michael Kith, <br /> Lead REHS, November 19, 2019). <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. 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. Details and results of the percolation test are summarized <br /> in the following table. <br /> LOGE 1946 Page 6 <br />
