Shallow Test <br />TEST HOLE PERCOLATION RATE <br />1 (Parcel 1) 27.8 Min/In <br />*See Results in Appendix. <br />6.7 Discussion of any potential problems predicted and/or the need for an engineered or <br />alternative septic system. In this area, the soils are classified as Acampo Sandy Loam. There is <br />a potential issue with the addition septic system related to percolation. An additional proprietary <br />nitrate reduction system will be required to reduce nitrates to the required standards. <br />6.8 Discussion of percolation rates in relation to the type, size and location of future leach <br />fields needed at the site. Based on the results of the percolation rate and the soils profile, it is <br />Dillon & Murphy's opinion that the subject parcel is suited for a typical on-site sewage disposal <br />system with the addition of the nitrate reduction system. The systems should be properly designed <br />and installed according to the current San Joaquin County criteria for standard septic systems. <br />Based on the depth to groundwater in the area, and the size of the existing parcel, it is our opinion <br />on that the installation of any new proposed septic system, if properly installed, should not affect <br />the quality of groundwater in the area. <br />7.0 CONCLUSION SECTION <br />The conclusions of this report are based on the information provided regarding the proposed <br />development, the use of the subject property, and the site conditions as they existed at the time we <br />excavated our test hole and performed the percolation test. It was assumed that the test hole and <br />percolation test results are representative of the subsurface conditions in the general area. <br />Our services were performed, our findings obtained, and our conclusions proposed in accordance <br />with generally accepted engineering principles and practices.
