MCLEOD PROPERTY Page No. 3 of nitrates was well below the Maximum Contaminant Level (MCL) allowed by law. VI. SOIL PROFILE AND PERCOLATION TESTS Two, 10 foot deep test holes were excavated by hand in the area of the existing and proposed homesite in order to determine the soil profiles in the general area. For approximate location of the test holes (PT) see the Parcel Map in the Appendix. The tests holes were logged by a civil engineer and a description of the soils encountered in each test hole is contained in the Appendix. The soils varied slightly between the two sites. The shallow percolating stratum at the existing homesite is a sandy silt and the shallow percolating stratum at the proposed homesite on the Designated Remainder property is a sandy clayey silt. The clay content at the second test location is reflected in a slower percolation rate. Two 36 inch deep by 8 inch diameter test hole were excavated by hand adjacent to the soil profile holes for performing shallow percolation tests. Two inches of gravel was placed in the bottom of each hole. A 3 inch diameter perforated pipe was then placed in. each hole and backfilled with gravel. Both holes were filled with water 24 hours prior to running the tests. The last half hour of the tests readings were witnessed by a county health official and the test data obtained is enclosed in the appendix. The percolation rates have been adjusted to account for the gravel and pipe backfill . Calculations for adjustments are on the test data sheets. A summary of the test results is presented next: Diameter of Depth of Test No. Hole (in. ) Hole (in. ) Percolation Rate min in PT-1 8 36 3 . 3 PT-2 8 36 11.5 VII CONCLUSION Based on the results of the shallow percolation tests, the soil profile, and the performance of the septic systems in the surrounding area, it is our opinion that both the existing and proposed homesites resulting from the proposed parcel split should IDERSG N P so G�
