THOMING PROPERTY Page No. 3 There is a domestic water well located near the existing mobile home. This well was sampled on July 14, 1995 and tested for the presence of nitrates and dibromochloropropane (DBCP) . Test results indicated that DBCP was non-detected and the level of nitrate was 31 mg/1, which is below the Maximum Contaminate Level (MCL) of 45 mg/l . A copy of the test results are included in the Appendix. VI . SOIL PROFILE AND PERCOLATION TESTS Two test holes were excavated to a depth of 10 feet in the area of the existing and proposed homesite in order to determine the soil profile in the general area. For approximate location of the test holes (PT) see the Parcel Map in the Appendix. The soil profile holes were logged by an engineer and a description of the soils encountered in the holes is contained in the Appendix. The surface soil consisted of a brown clayey silt. The surface soil was underlain by a tan silt which continued to the maximum depth explored. For a more detailed description of the soils encountered see the log of test holes. Shallow ( 36" deep) percolation tests were performed at the test hole locations. 4. 5 inch diameter holes were excavated and 2 inches of gravel was placed in the bottom of each hole. Two inch diameter perforated pipes were then placed and backfilled with gravel . The test holes were filled with water 24 hours prior to running the tests. The last half hour of the test 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 this adjustment is 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 4 36 31 PT-2 4 48 8 . 3 I;,os�e _
