Percolation Test Procedure <br /> Live Oak conducted the percolation test for the boring on March 2, 2017. Due to soil <br /> conditions observed, a four-hour test was selected. Water level measurements were <br /> taken every half hour during this four-hour period. Ted Tasiopoulos, Senior Registered <br /> Environmental Health Specialist at the San Joaquin County Environmental Health <br /> Department, observed the last.half hour of 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 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 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 test are summarized in the following table. <br /> Table 2.
