The <br /> borings were four inches in diameter, 3.40 and 3.43 feet deep, and were excavated by <br /> hand auger (Table 2). The locations of the borings are indicated on Plate 9. <br /> The soil in the borings was similar to, though sandier than, that described by the Soil <br /> Survey. Silty sand and sand with silt were encountered to the full depth of both holes. <br /> The logs for the soil borings are presented in Plates 10 and 11. <br /> Discussion of Soil Lithology <br /> Based on the soils observed in the borings, there appears to be moderate to good <br /> potential for percolation in the test locations. 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 /> LOGE 1322 Page 6 <br />
