Approximately 2 inches of "pea gravel' was placed in the <br /> bottom of the open soil boring and then the PVC pipe was installed on top of the gravel. "Pea <br /> gravel'was then used to backfill in the annular space. <br /> Presaturation of the percolation test holes occurred approximately 24 hours prior to the day of <br /> testing. The depth of water used to pre-soak was 12 inches above the bottom of the boring. <br /> 6.4 Condition of Borings after Presaturation <br /> After the 24-hour soak period, the presaturated hole was found to be intact and dry on the day <br /> of testing. <br /> 6.5 Percolation Test Procedure <br /> A percolation test was conducted for the boring on October 31, 2008 in accordance with the <br /> requirements of the EHD. A percolation test with a duration of 4 hours was performed for the <br /> test. The last half an hour of the test was observed by Kadeane, 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 /> "044 <br /> 902 Industria]Way•Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 02008 Nei[O.Anderson&Associates.Inc <br />
