Generally the surface soils consisted of top soil underlain with a layer of hard <br /> pan. As shallow percolation tests proved inadequate, deep percolation tests were <br /> performed. (See discussion and results later in this report) <br /> Two shallow percolation tests were performed in holes 9 inches in diameter <br /> by 42 inches deep backfilled with 2 inches of gravel. There was standing water in <br /> the holes at the start of the test. The two holes were filled with water 24 hours <br /> prior to running the test. The test holes for Parcel 1 and Parcel 2 were performed <br /> under a 4 hour test. The last half hour of the test readings were witnessed by a <br /> County Health Official and the test data obtained is enclosed in the Appendix. <br /> Parcel Number Percolation Rate (Shallow Test) <br /> 1 N/A <br /> 2 240 min/in <br /> Deep tests were performed by Neil O. Anderson and Associates (Anderson). <br /> They also performed shallow tests. See appendix for hole location. The <br /> soils lithology, as noted in the test pit, is noted on the data sheet provided by <br /> the County (See Appendix). Also, see section VI of this report for lithology. <br /> Future septic areas will most likely experience similar soil lithology. A <br /> summary of Anderson's results is as follows: <br /> Percolation Rate Percolation Rate <br /> Parcel Number Shallow Test Deep Test <br /> 1 31 .25 min/inch 125 min/inch <br /> 2 62.5 min/inch 83.3 min/inch <br /> The test holes by Anderson were dug with an augur. The holes were <br /> approximately 10" in diameter. The shallow tests were dug to four feet deep and <br /> the deep tests were approximately 25 feet deep. The test holes were dug August <br /> 4, 2003. The test were to be performed on August 6, 2003. The tests would <br /> have been performed on August 5, 2003 but they were postponed due to lightning. <br /> The holes were dug in the morning and the tests were performed in the morning. <br /> There was standing water noted but Anderson but depth was not measured. <br /> The test holes prepared by Anderson were intact when the tests began. <br /> There was standing water in the holes after the 24 hour pre soak period. See <br /> Appendix for the information. <br /> 3 <br /> C:\0338\Soil Suitability Report 072203 <br />
