The borings were four inches in diameter, 3.20 <br /> and 3.48 feet deep, and were excavated by hand auger. The locations of the borings <br /> are indicated on Plate 13. <br /> The soil in the borings was similar to that described by the Soil Survey. In boring P1, <br /> silty sand was encountered to a depth of 2.5 feet below ground surface, followed by fine <br /> sand with silt to the full depth of the hole. In boring P2, silty fine sand was encountered <br /> to the full depth of the hole. It was evident that the soil at P2 had been recently tilled; it <br /> was soft and tended to collapse into the boring. The logs for the soil borings are <br /> presented in Plates 14 and 15. <br /> Discussion of Soil Lithology <br /> Based on the soils observed in the borings, there appears to be good 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 /> • LOGE 1714 Page 10 <br />
