A percolation test with a duration of 4 hour was performed for the <br /> test. The last half an hour of the test was observed by Ted Tasiopoulos, Inspector, 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 feet (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 hours. <br /> 6.6 Percolation Test Forms and Results <br /> The completed percolation test form is included in the appendix of this report. <br /> A shallow percolation test is defined by the EHD as being between 36 and 42 ''fiches in depth; a <br /> satisfactory percolation rate for a shallow test is less than or equal to 60 r> inutes 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 minutes per inch or less. One percolation test must <br /> demonstrate a satisfactory percolation rate within the proposed septic system disposal field of <br /> each parcel to utilize a standard septic system. Details of the percolation tests are summarized <br /> in the table below. <br /> Table 3 <br /> Summary of Percolation Tests <br /> Percolation Percolation <br /> Test No., Comments <br /> Test Rate Test Duration <br /> Date Tested Depth (feet) (minutes/inch) ( notes) <br /> P-1 (shallow) 3.13 4.90 4-hr Satisfactory <br /> 7-11-08 percolation-_ <br /> P-2 (shallow) 3.12 11.9 4-hr Satisfactory <br /> 7-11-08 \; percolation rate <br /> Note: A satisfactory percolation rate for a"shallow"test is less than or equal to 60 minutes per-inch. <br /> A satisfactory percolation rate for a"deep"test is less than or equal to 30 minutes per inch. <br /> "044 <br /> 902 Industrial Way• Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 (02008 Neil O.Anderson&Associates,Inc <br />
