Table 7. Result of Nitrate Loading Calculation <br /> Variiable Value Units Description <br /> Long-terra average concentration of percolating <br /> Nc 5.30 mg/L-N effluent <br /> The IIS EPA recommended MCL for nitrate in drinking water is 10 mg/L-N. In a worst <br /> case situation, the maximum buildup of nitrates from the use of septic systems in the <br /> aquifer is predicted to be 5.30 mglL-N. The result of the nitrate loading estimate is well <br /> 01, below the maximum drinking water standard. <br /> Discussion of Nitrate Loadinc <br /> i Results <br /> Total Nitrate Impact <br /> Based on the method and assumptions described, the result of the nitrate loading <br /> estimate indicates that the existing and proposed residences and proposed <br /> development on the Site should not cause a buildup of nitrates in the aquifer above 10 <br /> mg/L-N. Because of the satisfactory result, no mitigation measures are warranted. <br /> E <br /> LOGE1005 Page 13 <br />
