w <br /> October 13, 2004 <br /> OA Project Number: E040109A <br /> 6.8 Discussion of Septic System Sizing <br /> Septic System Construction should follow the San Joaquin County On-Site Wastewater Disposal <br /> Standards where applicable. <br /> 7.0 CONCLUSIONS <br /> 6. In summary, satisfactory percolation rates of the soil were achieved in the proposed septic disposal <br /> areas of both parcels. The parcels appear suitable for a standard septic system. We recommend that <br /> v <br /> the design and installation of the septic systems follow the requirements established by the EHD. <br /> No ground water was encountered in any of the borings drilled on the property, and the depth to <br /> ground water is approximately 100-110 feet below the ground surface for the period of Fall 1998 <br /> ` and Spring 1999. The water sample collected was found to have 6 Mg/L- 3,well below the <br /> maximum contaminant level (MCL) set by the US EPA of 45 mg/L-N 3 BCP w�s not detecte <br /> vim in the water sample. — <br /> 8.0 LIMITATIONS <br /> ` The conclusions of this report are based on the information provided regarding the existing and <br /> proposed development, the use of the subject property, and the site conditions as they existed at the <br /> time we excavated our test holes and performed the percolation tests. It was assumed that the test <br /> ` holes and percolation test results are representative of the subsurface conditions in the general area. <br /> Our professional services were performed, our findings obtained, and our conclusions proposed in <br /> accordance with generally accepted engineering principles and practices.
