GROUND WATFR <br /> The owner stated that the ground water on-site Is thirty feet below the surface. <br /> From the San Joaquin County Flood Control and Water Conservation Study, we <br /> find that the ground water depth Is approximatey twenty-two feet (Fxhibft 2) <br /> and that the water gradient Is approximated four feet/mlle, falling westerly. <br /> (Exhibft 3). <br /> We contacted F.G.L. 1-aboratory to take and test their water. The results are <br /> attached as Exhibits 4 and 5. <br /> 5011-5 AND PFRCOLATION TESTS <br /> Per the "Soils of San Joaquin County'as published *the University of California, <br /> the roll Is Hanford Loamly Sand. <br /> Under permit from the San Joaquin County Health Department, percolation tests <br /> were run September 19.1992, The tarts passed with results as shown on Exhlblt <br /> 6. <br /> Test 1 war near the home (Parcel 1) and percolated at 10 minutes/Inch. This Is <br /> compatlble with the septic system, history and roll type. <br /> Test 2 was run In the vineyard and percolated at 7.5 minutes/Inch. <br /> Barad upon the range of the percolation test results the following <br /> recommendations are conservative. <br /> CONCLUSION <br /> Although the percolation rates qualify for 6,000 S.F. percolation areas. I <br /> recommend that 8.000 S.F. ba set aside for leach arae&. The percolation rates <br /> we obtained are the best we have had in this area end I chose to Interpret them <br /> conservatively. <br /> Ba&ed upon the parcolation test results. Interviews and &oil typo, it Is my opinion <br /> that the subJect property Is rultable for septic tank and leach field,and that the <br /> use of the septic system should not daarada the existing groundwater at the <br /> density proposed.
