The borings <br /> were four inches in diameter, 3.10 and 3.24 feet deep, and were excavated by hand <br /> auger (Table 2). <br /> The locations of the borings are indicated on Plate 13. <br /> The soil in the borings was similar to that described by the Soil Survey. Silty, fine to <br /> medium sand was encountered to the full depth of both holes. The soil log is presented <br /> on Plate 14. <br /> Discussion of Soil Lithology <br /> Based on the soil observed in the boring, there appears to be good potential for <br /> percolation in the shallow soil zone. Sandy soils generally have a much greater <br /> potential for percolation than fine-grained or cemented soils. However, a percolation <br /> test is the only accepted method for determining the suitability of the soils for a septic <br /> disposal area. Percolation test results are discussed in the following section. <br /> Percolation Test <br /> Shallow percolation tests were conducted in the proposed septic disposal areas of the <br /> Site. The soil borings discussed above were used for the percolation test holes (Plate <br /> LOGE 1908 Page 6 <br />
