We recommend that any future septic system layout follow the method <br /> prescribed in the Sewage Standards (1996) of the EHD. We do not foresee any adverse <br /> conditions. <br /> 7.0 CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, a satisfactory percolation rate was achieved in the proposed septic disposal area <br /> for the future residence. No ground water was encountered in the boring drilled on the <br /> property, and the depth to ground water is approximately 10 to 20 feet below the roundd <br /> surface for the period of Fall 1998 and Spring 1999. <br /> Based on the results of this study, our office has found the soils to be suitable for a standard <br /> septic system with a filter bed disposal area for the Site. We recommend that the design and <br /> installation of the septic system follow the requirements established by the EHD. <br /> 8.0 LIMITATIONS <br /> The conclusions of this report are based on the information provided regarding the existing <br /> and proposed development, the use of the subject property, and the site conditions as they <br /> existed at the time we excavated our test holes and performed the percolation tests. It was <br /> assumed that the test holes and percolation test results are representative of the subsurface <br /> conditions in the general area. <br /> 8 <br />
