6.5 The Test Conformed to San Joaquin County Policy EHD 02-02 (Correct Depth, <br /> diameter, 2" gravel, 6" Water Refill, Correct Readings Recorded): The percolation test <br /> conformed to San Joaquin County Policy EHD 02-02. <br /> 6.6 Complete Percolation Test Form (Including Readings) Was Provided With REHS <br /> Verification Signature. The Rate Was Correctly Calculated Using the Last Reading: <br /> See Appendix for Test Result Form. <br /> SHALLOW TEST HOLE PERCOLATION RATE <br /> 1 30.00 MINJIN. <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 a an Archerdale Clay Loam. <br /> Due to this classification and percolation rates, a standard septic system similar to those found on <br /> surrounding parcels would be recommended (See Appendix). <br /> 6.8 Discussion of Percolation Rates in Relation to the Type, Size and Location of future <br /> leach fields at the site: Based on the results of the percolation rates and the soils profile, it is <br /> Dillon &Murphy's opinion that the subject proposed parcel is suited for a typical on-site sewage <br /> disposal system. This system should be properly designed and installed according to the current <br /> San Joaquin County criteria for standard septic systems. <br /> Based on the depth to groundwater in the area, and the size of the proposed parcel, it is our <br /> opinion that the installation of any new proposed septic system, if properly installed, should not <br /> adversely affect 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 <br /> we excavated our test hole and performed the percolation test. It was assumed that the test hole <br /> and 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.
