Live Oak presaturated the percolation test hole approximately 24 hours prior to the percolation testing. The hole was filled with water to a height of 12 inches above the bottom of the boring for the presaturation. On the day of testing, the hole was found to be intact and dry. Percolation Test Procedure Live Oak conducted the percolation test for the boring on May 17, 2019. Based on initial percolation rates observed, a four-hour test was selected. Water level measurements were taken every 30 minutes during this one-hour period. The last ten minutes of the test were observed by Naseem Ahmed, Registered Environmental Health Specialist at the San Joaquin County Environmental Health Department. An electronic well sounder with a depth accuracy of 1/100th foot was utilized for the water level measurements. The water level was measured against a fixed reference point on the well casing. Measurements were recorded on the data sheet in decimal feet. When necessary after measuring the water level, the hole was refilled with water to a level of six inches or more above the bottom of the hole. Percolation Test Results The completed percolation test form is included in Appendix 3 of this report. The form was signed by Mr. Ahmed and indicates a percolation rate for the hole based on the final water drop observed. Per San Joaquin County Environmental Health Department's definition, a shallow percolation test hole has a depth between 36 and 42 inches; a satisfactory percolation rate for a shallow test is greater than or equal to 1 minute per inch (min/in) but less than or equal to 60 min/in drop. For the Site to utilize a standard septic system, one percolation test must demonstrate a satisfactory percolation rate within the proposed septic system disposal field. Details and results of the percolation test are summarized in the following table. Table 2. Percolation Test Summary Test No., Percolation Test Percolation Rate Test Duration Comments Date Tested Depth (ft.) (minutes/inch) (see notes) P1, 5/17/2019 Shallow Test 3.03 5.2 4 hr. Satisfactory perc rate' Note: A satisfactory percolation rate for a "shallow" test is greater than 1 but less than or equal to 60 minutes per inch. 1 Per San Joaquin County Environmental Health Department, a rate between 5.0 and 30 min/in requires an eight-foot separation between the bottom of dispersal system and ground water, or mitigation by system design or enhancement.
