Y o t i Ii l E Soil Suitability Study APN: 209-150-16 UP-96-6 'E so near the ground surface is because the test hole was excavated in the winter season and immediately after some recent rains which is when the water table would be at its highest level during the € year . E [ Percolation Tests : A shallow percolation test was conducted and F performed in accordance with the percolation test procedures outlined in the "Manual Of Septic Tank. Practice" , published by the Department Of health, Education And Welfare and the requirements of the San Joaquin County Public Health Service, Environmental Health Division. A shallow Percolation Test Hole, No. PH was excavated to a depth of 35" . Then 2" of rock was placed in the bottom of the test hole and presoaked over--night . Since no water remained in the percolation test hole after the over-night soaking process , the drop in water level was then measured at 30 minute intervals for 4 hours, and the reading in the last 30 minutes resulted in a percolation rate of 120 minutes per inch for the subject property. Under drier test conditions the percolation rate could well have conformed to the County' s minimum standard of 60 minutes per inch since the standard was maintained for 3 1/2 hours and only -illedtconfaori"�tlie las�t1�%2jhour . The test was performed under v' '-satif ated con`d ti'o�ns c ated by recent rainstorms and rainfall occurring on the very day of the percolation rate determination. The result of the percolation test is summarized and tabulated as follows : TEST RESULTS : Test Hole Percolation Rate Minimum Usable Mound or NO .
