Table 5. Result of Nitrate Loading Calculations <br /> Variable Value Units Description <br /> Nc 7.9 mg/L-N Long-term average concentration of percolating effluent, <br /> homesite parcel <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 7.9 mg/L-N. <br /> The result of the nitrate loading estimate is 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 existing development on the homesite parcel of the Site <br /> should not cause a buildup of nitrates in the aquifer over the MCL of 10 mg/L-N. No <br /> nitrate mitigation is recommended. <br /> LOGE 20-12 Page 14 <br />
