• 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 percolation test <br /> hole was found to be intact and dry. <br /> Percolation Test Procedure <br /> Live Oak conducted the percolation test for the boring on November 16, 2016. Due to <br /> initial percolation rates observed, a one-hour test was selected. Water level <br /> measurements were taken every ten minutes during this one-hour period. Ted <br /> Tasiopoulos, Senior Registered Environmental Health Specialist at the San Joaquin <br /> County Environmental Health Department, observed the test. <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 an approximate level of 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. Tasiopoulos 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 36 and 42 inches; a satisfactory percolation <br /> rate for a shallow test is less than or equal to 60 minutes per inch (min/in) drop. For the <br /> Site to utilize a standard septic system, one percolation test 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.
