-' There is currently one well on the subject property. The <br /> results of the Dibromochloropropane (DBCP) and nitrates are <br /> included in the enclosed appendix. <br /> 't VI. SOIL PROFILE AND PERCOLATION TESTS <br /> `y Three test holes were ekcavated to depths of 3 . 0 feet in <br /> the areas of the proposed homesites . The purpose of the test <br /> holes was to determine percolation rates in these areas . For <br /> +� approximate location of the test holes, see the Tentative Parcel <br /> Map in the Appendix. Holes were prepared in accordance with <br /> County standards . <br /> Generally the surface soils consisted of a sandy loam as <br /> classified by visual inspection. As shallow percolation tests <br /> Proved adequate for conventional septic systems , no further soil <br /> �-' exploration was necessary, <br /> The Percolation tests were performed in 8 inch diameter by <br /> �. 35 inch deep test holes backfilled with two inches of gravel . <br /> All holes were filled with water 24 hours prior to running the <br /> test. A four hour percolation test was performed and the last <br /> half hour of the test readings were witnessed by a county health <br /> Official and the test data obtained is enclosed in the Appendix. <br /> The results of the tests yield the following results : <br /> Parcel 1 (Hole 1 ) - 7 . 5 min/inch <br /> F Parcel 2 (Hole 3 ) - 7 . 5 min/inch <br /> Parcel 3 (Hole 2 ) - 17 min/inch <br /> La <br /> VII. CONCLUSION <br /> Based on the results of the percolation tests , the <br /> zoilprofile , and the performance of the septic systems in the <br /> surrounding area, it is Dillon & Murphy' s opinion that the new <br /> homesites resulting from the proposed parcel split of the subject <br /> property are suited for the construction of a typical on site <br /> sewage disposal system. The proposed system, however, should be <br /> (NO properly designed and installed according to current San Joaquin <br /> County criteria. <br /> It should be noted that the location of each of the <br /> percolation tests were chosen as the most likely location for a <br /> disposal field. Although it is not anticipated that soil <br /> conditions vary greatly over the subject project, if the actual. <br /> L. location of a proposed disposal field varies significantly from <br /> the test locations, the test data should not be considered <br /> accurate of other locations . <br /> Based on the depth to ground water in the area, and the <br /> size of the proposed parcels, it is our opinion that the <br /> LW 2 <br /> La <br />
