CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, the soil conditions examined near the location of the septic system drain <br /> field appear to be suitable. A satisfactory soil percolation rate of 7.14 minutes per inch <br /> was observed. <br /> The depth to ground water based on recent aquifer levels is estimated to be less than <br /> 10 feet below ground surface. The ground-water flow direction is to the east and <br /> southeast. <br /> The on-site domestic water well was tested for nitrate and DBCP. Nitrate and DBCP <br /> were not detected in the sample. <br /> The use of on-site septic tanks and drain field systems on the Site is not expected to <br /> cause a buildup of nitrate in the aquifer above 2.47 mg/L-N, which is well below the US <br /> EPA drinking water recommendation of 10 mg/L-N. In fact, the actual impact to the <br /> aquifer will be much less since the equation is conservative and overestimates impacts. <br /> We believe the Site suitable for development with the use of standard septic systems <br /> utilizing leach lines and sumps or a filter bed. <br /> We do not anticipate that the ground water quality will be negatively impacted by the <br /> project, primarily due to the low calculated nitrate level. No nitrate mitigation is <br /> recommended. <br /> LOGE1120 Page 14 <br />
