L LFebruary 13,2007 NOA Project Number: E07010A 6.7 Discussion of Percolation Test Results The soils within the sewage disposal areas of the site have demonstrated a satisfactory percolation rate in accordance with the requirements of the EHD for the use of a standard septic system. 6.8 Discussion of Septic System Sizing Septic System Construction should follow the San Joaquin County On-Site Wastewater Di posa! j Standards where applicable. L L L7.0 CONCLUSIONS In summary, satisfactory percolation rates of the soil were achieved in the proposed septic disposal areas of the Site. The project appears to be suitable for development utilizing a standard septic Lsystem No ground water was encountered in any of the borings drilled on the property.The on-site water L well was tested for nitrate and DBCP. DBCP was found at 0.05 ug/L,which is below the maximum contaminant drinking water limit of 0.2 ug/L. Nitrate concentration in ground water was found to be 31.8 mg/L-N031which is below the maximum contaminant drinking water limit of 45 mg/Ir NO3. L8.0 LIMITATIONS The conclusions of this report are based on the information provided regarding the existing and L proposed development, the use of the subject property,and the site conditions as they existed at the time we excavated our test holes and performed the percolation tests. It was assumed that the test holes and percolation test results are representative of the subsurface conditions in the general area. Our professional services were performed,our findings obtained, and our conclusions proposed in accordance with generally accepted engineering principles and practices.
