• Live Oak presaturated the percolation test holes approximately 24 hours prior to the <br /> percolation testing. Each hole was filled with water to a height of 12 inches above they <br /> bottom of the boring for the presaturation. On the day of testing, the holes were found <br /> to be intact and dry. <br /> Percolation Test Procedure <br /> Live Oak conducted the percolation tests for the borings on March 30, April 3, and May <br /> 17, 2017. Due to soil conditions observed, four-hour tests were selected. Water level <br /> measurements were taken every 30 minutes during this four-hour period. The final half <br /> hour of each test was observed by Michael Escotto or Steven Shih, Senior Registered <br /> Environmental Health Specialists 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 an approximate level of six inches 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. Escotto or Mr. Shih and indicate the percolation rate for each f � <br /> hole 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 /> • <br /> LOGE 1704 Page 7 <br />
