Table 6. Result of Nitrate Loading Calculation <br /> Variable Value Units Description <br /> Nc 3.3 mg/L- Long-term average concentration of percolating <br /> effluent <br /> j. <br /> The US 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 3.3 mg/L-N. The result of the nitrate loading estimate is well <br /> below the maximum drinking water standard. <br /> Discussion of Nitrate Loading Results <br /> Total Nitrate Impact <br /> Based on the method and assumptions described, the result of the nitrate loading <br /> estimate indicates that the proposed church expansion on the Site should not cause a <br /> buildup of nitrates in the aquifer above 10 mg/L-N. Because of the satisfactory result, <br /> no mitigation measures are warranted. <br /> LOGE 1917 Page 14 <br />
