Percolation Test Procedure <br /> Live Oak conducted the percolation tests for the borings on July 18, 2013. Due to initial <br /> percolation rates observed, four-hour tests were selected. Water level measurements <br /> were taken every 30 minutes during this four-hour period. The last half hour of each <br /> test was observed by Ted Tasiopoulos, Senior Registered Environmental Health <br /> Specialist at the San Joaquin County Environmental Health Department. /6 \ <br /> An electronic well sounder with a depth accuracy of 1/100th foot was utilized for the ( J <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 forms are included in Appendix 3 of this report. The <br /> forms were signed by Mr. Tasiopoulos and indicate the percolation rate for each hole <br /> based on 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. A deep <br /> percolation test hole has a depth greater than 3.5 up to 25 feet; a satisfactory <br /> percolation rate for a deep test is 30 min/in or less. For the Site to utilize a standard <br /> septic system, one percolation test (either a shallow or deep test) must demonstrate a <br /> satisfactory percolation rate within the proposed septic system disposal field. <br /> Details and results of the percolation tests are summarized in the following table. <br /> I naF Vsrn Page 6 <br />
