The soils of these <br /> parcels appear to be suitable for a septic system udliiing shallow leach lines or a filter bed.- <br /> 6.8; Discussion of Septic System Sizing <br /> Septic system construction should follow the San Joaquin County On-Site Wastewater Disposal <br /> f Standards where applicable. <br /> F1 7.0 CONCLUSIONS <br /> In summary, satisfactory percolation rates of the soil were achieved in the proposed septic disposal <br /> areas of all of the parcels. The proposed Parcels appear suitable for a standard septic system. <br /> I No ground water was encountered in any of the borings drilled on the property. The on-site water <br /> well was tested for nitrate and DBCP. DBCP was concentration in ground water was found to be <br /> .0823 µg/L,which is well below the maximum contaminant drinking water limit of.2 µg/L. Nitrate <br /> was not detected in the ground water sample. <br /> 10 <br />
