Septic system construction should follow the San Joaquin County On-Site Wastewater Disposal <br /> Standards where applicable. o <br /> rk <br /> r <br /> - 7.0 CONCLUSIONS <br /> In summary, satisfactory percolation rates of the soil were achieved in the proposed septic disposal <br /> areas of the Site. The septic disposal areas of the proposed parcels appear suitable for a standard <br /> septic system. <br /> No ground water was encountered in any of the borings drilled on the property. The depth to <br /> �, ground water was found to be between approximately 60 and 70 feet below the ground surface for <br /> 1 ► the period of Fall 1998 and Spring 1999. The on-site water well was tested for nitrate and DBCP. <br /> i <br /> r <br /> 9 <br /> r <br /> { �s <br />
