The borings were four inches in diameter and were excavated by hand auger. <br /> Depths of the borings were 3.15, 3.25, 7.79, and 10.05 feet below ground surface. The <br /> boring locations are indicated on Plate 2. �j <br /> The soil in the borings was similar to that described by the Soil Survey. Hardpan was <br /> generally encountered from five to seven feet below ground surface, and a layer of <br /> loose sand was encountered at approximately nine feet depth. The log for the soil <br /> borings is presented in Plate 9. <br /> Discussion of Soil Lithology <br /> Based on the soils observed in the borings, there appears to be some potential for <br /> percolation. Sandy soils generally have a much greater potential for percolation than <br /> fine-grained or cemented soils. However, a percolation test is the only accepted <br /> method for determining the suitability of the soils for a septic disposal area. Percolation <br /> test results are discussed in the following section. <br /> LOGE1017 Page 5 <br />
