A percolation test with a duration of four (4) hours was performed <br /> for the test. The last half an hour of the test was observed by Ted Tasiopoulos, Inspector, <br /> EHD. <br /> Measurement of the water level during the percolation test was from a fixed reference point on <br /> the PVC casing using an electric well sounder with a depth accuracy of 1/100th foot. All <br /> tabulated values on the field data sheet are in decimal feet. After water drop was observed, <br /> the holes were checked for refill. The refill level was approximately 0.5 ft (6 inches) of water <br /> above the bottom level of the percolation test hole. The readings were taken every 30 minutes <br /> for a period of four (4) hours. <br /> 6.6 Percolation Test Forms and Results <br /> The completed percolation test form is included in the appendi tof this report. <br /> A shallow percolation test is defined by the EHD as bei etween 36 and 42 inches in depth; a <br /> satisfactory percolation rate for a shallow test is less than or equal to 60 minutes per inch drop. <br /> A deep percolation test is defined as being between 3.5 and 25 feet in depth; a satisfactory <br /> percolation rate for a deep test is 30 min/in or less. One percolation test must demonstrate a <br /> satisfactory percolation rate within the proposed septic system disposal field of each parcel to <br /> utilize a standard septic system. Details of the percolation tests are summarized in the table <br /> below. <br /> Table 3. <br /> Summary of Percolation Tests <br /> Test No., Percolation Percolation Test Comments <br /> Date Tested DepT sfeet) (minutes inch)t RaDuration —tseeno <br /> P-1 (shallow) 3 � Satisfactory <br /> .2 4.54 4-hr , <br /> 1-29-2009 percolation rate <br /> Note: A satisfactory percolation rate for a"shallow"test is-19s than or equal to 60 rn utes per inch. / <br /> A satisfactory percolation rate for a"deep"test is less than or equal to 30 minut per inch. <br /> 6.7 Discussion of Percolation Test Results <br /> The soils within the sewage disposal area of the site have demonstrated a satisfactory <br /> percolation rate in accordance with the requirements of the EHD for the use of a standard <br /> septic system. <br /> '-'44 <br /> 902 Industrial Way•Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 ®2008 Neil O.Anderson&Associates,Inc <br />
