Generally speaking, sandy soils have much <br /> greater potential for percolation than fine-grained or cemented soils. <br /> Ap ercolation test is the best method to determine the suitability of the soils. Please see the next <br /> section for percolation test results. <br /> f-? 6.0 PERCOLATION TEST INFORMATION <br /> 6.1 Percolation Test Locations <br /> A site map indicating the locations of the percolation test holes is included as Plate 1 in the appendix <br /> of this report. <br /> 6.2 Number of Percolation Tests <br /> FI One shallow percolation test were conducted on each parcel of the Site, and one deep percolation <br /> test was conducted on Parcel one and two of the Site, for a total of three shallow and three deep <br /> percolation tests. <br /> 6.3 Boring Preparation and Presaturation <br /> F1__1 Two deep soil borings were drilled on the Site with a truck-mounted deep rock augur rig on <br /> October 20, 2005. One deep boring was drilled on October 27, 2005. Three shallow borings were <br /> F1advanced by hand-auguring on October 13,2005. <br /> 7 <br /> I <br /> Fit <br />
