A percolation test is the best method to determine the suitability of the <br /> L soils. Please see the next section for percolation test results. Generally speaking, sandy non- <br /> cemented soils have much greater potential for percolation than fine-grained cemented soils. <br /> L6.0 PERCOLATION TEST INFORMATION <br /> L6.1 Percolation Test Locations <br /> A site map indicating the locations of the percolation test holes is included as Plate 1 of this report. <br /> L6.2 Number of Percolation Tests <br /> L One shallow percolation test were conducted on each proposed parcel of the Site, for a total of four <br /> shallow <br /> L <br /> L 8 .,04 <br /> L <br />
