Generally the surface soils consisted of a sandy loam. As shallow percolation <br /> tests proved adequate for conventional septic systems, no further soil exploration was <br /> necessary. <br /> Two percolation tests were performed in holes with 8 inch in diameters by 42 <br /> inches deep backfilled with 3 inches of gravel. The two holes were filled with water 24 <br /> hours prior to running the test. The test holes for Parcels 1 and 2 were performed <br /> under a 4 hour test. The last half hour of the tests readings for Parcels 1 and 2 were <br /> witnessed by a County Health Official and the test data obtained is enclosed in the <br /> Appendix. <br /> Parcel Number Percolation Rate <br /> 1 30 minutes/inch <br /> 2 34 minues/inch <br /> VII. GROUNDWATER <br /> A Groundwater test was performed on the existing well. The results can be <br /> found in the appendix. <br /> VIII. CONCLUSION <br /> Based on the results of the percolation tests and the soil profile, it is Dillon & <br /> Murphy's opinion that the existing homesites resulting from the proposed parcel split of <br /> the subject property are suited for a typical on-site sewage disposal system. The <br /> proposed system however, should be properly designed and installed according to the <br /> current San Joaquin County criteria. <br /> Based on the depth to ground water in the area, and the size of the proposed <br /> parcels, it is our opinion that the installation of any new proposed septic system, if <br /> properly installed, should not adversely affect the quality of ground water in the area. <br /> 2 <br /> CA0241\MURRY RD SOILS REPORT 082002 <br />
