Table 3. Results of Nitrate Loading Calculations <br /> Parcel Parcel Size (Acres) Nc (No Development) Nc (Hypothetical <br /> Future Homes) <br /> 1 47.77 0.3 mg/L-N 1.1 mg/L-N <br /> 2 49.80 0.3 mg/L-N 1.1 mg/L-N <br /> 3 45.80 0.3 mg/L-N 1.2 mg/L-N <br /> 4 39.66 0.3 mg/L-N 1.3 mg/L-N <br /> Based on the method and assumptions described, maintaining zero development on <br /> each parcel would result in a buildup of nitrates in the aquifer up to 0.3 mg/L-N, <br /> equivalent to the measured rainwater concentration. <br /> Were two houses to be placed on each parcel, the maximum buildup of nitrates in the <br /> aquifer from the use of septic systems on the Site is predicted to be 1.1 mg/L-N for <br /> Parcels 1 and 2, 1.2 mg/L-N for Parcel 3, and 1.3 mg/L-N for Parcel 4. This calculation <br /> assumes future houses which are not planned for the Site. <br /> The US EPA recommended MCL for nitrate in drinking water is 10 mg/L-N. In all the <br /> scenarios, the results of the nitrate loading calculation are well below maximum drinking <br /> water standard. <br /> Discussion of Nitrate Loading Results <br /> Total Nitrate Impact <br /> Based on the method and assumptions described, the results of the nitrate loading <br /> estimates indicate that the impact to the ground water from no development or from the <br /> placement of two houses with up to eight bedrooms total on each parcel would be well <br /> below 10 mg/L-N. <br /> LOGE 20-54 Page 13 <br />
