Table 4. Result of Nitrate Loading Calculation <br /> Variable Value Units Description <br /> Nc 4.5 mg/L-N Long-term average concentration of percolating effluent <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 in the aquifer from the use of septic <br /> systems on the Site is predicted to be 4.5 mg/L-N. <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 development on the Site should not cause a <br /> buildup of nitrates in the aquifer above the maximum drinking water standard. <br /> LOGE 20-56 Page 12 <br />
