The details of the nitrate loading calculation are included in the attached Plate. <br /> The results of the calculation are presented in the following table. <br /> Table 7. Result of Nitrate Loading Calculation <br /> Variable Value Units Description <br /> Long-term average concentration of percolating <br /> Nc 1.87 mg/L-N effluent <br /> The US EPA recommended MCL for nitrate in drinking water is 10 mg/L-N. In a <br /> worst-case situation, the maximum buildup of nitrates from the use of septic <br /> systems in the aquifer is predicted to be 1.87 mg/L-N. The result of the nitrate <br /> loading estimate is below the maximum drinking water standard. <br /> Page 6-3 <br />
