The depth of water used to pre-soak was 12 inches above the bottom of the boring. <br /> t 6.4 Condition of Borings after Presaturation <br /> After the 24-hour soak period, the presaturated holes were found to be intact and dry on the <br /> day of testing. <br /> 6.5 Percolation Test Procedure <br /> Percolation tests were conducted for the borings on May 29, 2008 in accordance with the <br /> requirements of the EHD. 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 Michael Escotto a Registered <br /> Environmental Health Specialist, 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 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 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 6 <br /> Summary of Percolation Tests <br /> Percolation Percolation <br /> Test Number, Test Comments <br /> Date Tested Dep It(�) (minutes/inch)Rate Duration (see notes) <br /> P-1 (shallow) 3.05 83.3 4-hr Failing percolation rate <br /> 5-29-08 <br /> P-1 (deep) 5.25 62.5 4-hr Failing percolation rate <br /> 5-29-08 <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 /> 902 Industrial Way•Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 12008 Nei(0.And...von&Assuetntes.In( <br />
