Percolation Test Procedure <br />Live Oak conducted the percolation testing for the borings on October 29, 2021 (Parcel <br />2) and December 22, 2011 (Parcel 1). Mr. Chesney completed the percolation test on <br />Parcel 3 on October 12, 2010. Due to the soil types observed, four-hour tests were <br />selected for Parcels 1 and 2. Water level measurements were taken every 30 minutes <br />during the four-hour period. The last 30 minutes of each test were observed by Aldara <br />Salinas or Ted Tasiopoulos, Registered Environmental Health Specialists at the San <br />Joaquin County Environmental Health Department. Mr. Chesney's test was also <br />certified by Mr. Tasiopoulos. <br />An electronic well sounder with a depth accuracy of 1/100th foot was utilized for Live <br />Oak's water level measurements. The water level was measured against a fixed <br />reference point on the well casing. Measurements were recorded on the data sheet in <br />decimal feet. When necessary after measuring the water level, each hole was refilled <br />with water to a level of approximately six inches above the bottom of the hole. <br />Percolation Test Results <br />The completed percolation test forms for Parcels 1 and 2 are included in Appendix 3 of <br />this report. The forms were signed by Ms. Salinas or Mr. Tasiopoulos and indicate a <br />percolation rate for each hole based on the final water drop observed. Live Oak does <br />not have a copy of the original test form for Parcel 3; the permit, however, states, "perc <br />test this date, shallow test passing rate." <br />Per San Joaquin County Environmental Health Department's definition, a shallow <br />percolation test hole has a depth between 18 and 42 inches; a satisfactory percolation <br />rate for a shallow test is greater than or equal to 1 minute per inch (min/in) but less than <br />or equal to 60 min/in drop. For the Site to utilize a standard septic system, one <br />percolation test hole on each proposed parcel must demonstrate a satisfactory <br />percolation rate. <br />Details and results of the percolation testing are summarized in the following table. <br />LOGE 2141 Page 7 <br />
