Fry Property <br /> Page 3 <br /> The residences on parcel-1 and parcel-2 currently utilize on-site water wells for their source <br /> of water. The county Health Department requires that samples be obtained for each property to <br /> determine levels of nitrate and the presence of dibromochloropropane (DBCP). <br /> Water was sampled from the on-site wells on August 26, 1997 and tested for the presence <br /> of nitrates and dibromochloropropane (DBCP). For both parcels,test results indicated that DBCP <br /> was non-detected and the level of nitrate was 27 mgll, which is below the Maximum Contaminate <br /> Level (MCL) of 45 mgll. A copy of the test results is included in the Appendix. <br /> VI. SOIL PROFILE AND PERCOLATION TESTS <br /> Two test holes were excavated to a depth of 7.5 feet in the vicinity of the leech fields in <br /> order to determine the soil profile in the general area. For approximate location of the test holes(PT) <br /> see the Parcel Map in the Appendix. The soil profile holes were logged by an engineer and a <br /> description of the soils encountered in the holes is contained in the Appendix. The upper 7 to 7.5 <br /> feet of material encountered in the test holes consisted of very fine to fine sand. The sand was <br /> underlain by a highly cemented stratum of very fine to fine sand which continued to the maximum <br /> depth explored. For a more detailed description of the soils encountered see the Log of Test Holes. <br /> Due to the presence of sandy soils in the upper stratum, 3.0 foot deep percolation tests were <br /> performed at each of the test hole locations. Two 8.0-inch diameter test holes were excavated and <br /> 2-inches of gravel was placed in the bottom of each hole. A 2.0-inch diameter perforated pipe was <br /> then placed in each hole and backfilled with gravel. The test holes were filled with water 24 hours <br /> prior to running the tests. The last half hours of the test readings were witnessed by a county health <br /> official and the test data obtained is enclosed in the appendix. The percolation rates have been <br /> adjusted to account for the gravel and pipe backfill. Calculations for this adjustment are on the test <br /> data sheets. <br /> A summary of the test results is presented next: <br /> Diameter of Depth of <br /> Test No. Hole in. Hole in. Percolation Rate (min/in) <br /> PT-1 8 36 4.5 <br /> PT-2 8 36 4.5 <br />
