r.• MULLER RD. Page No. 3 Two ground water samples were obtained from existing wells, one on each of the parcels. For approximate well locations see the location map. Both samples were obtained on September 4, 1998 by a representative of our office and tested for the presence of nitrates and dibromochloropropane (DBCP). Test results indicated that DBCP was non-detected in both wells and nitrate levels were non-detected in well I and 14 mg/L in well 2. 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 areas of the proposed parcel splits in order to determine the soil profile in the general area. The test holes were excavated with a truck mounted drill rig utilizing a 4.5 inch diameter continuous flight auger. For approximate location of the test holes (PT) seethe Parcel Map, Plate No.l. The soil profile holes were logged by an engineer and a description of the soils encountered is contained on the Log of Boring Sheets, Plates No.2 and 3 in the Appendix. A total of 10 shallow, 36" deep, percolation tests were performed, one on each of the proposed lots. For each of the tests a 4.0 inch diameter hole was excavated and 2 inches of gravel was placed at the bottom of each hole. A 2.25 inch diameter perforated pipes was then placed in each hole 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 sheet. A summary of the results is presented next: P PERS y D n Z W O � q'pSpG♦ P
