table presents a summary of the assumptions for the nitrate loading calculation for the <br /> Site, as presented in Plate 10. <br /> Table 6. Assumptions for Nitrate Loading Calculation <br /> Variable Value Units Description <br /> Q 242 ✓ gpd Effluent flow rate <br /> Nw 85 ✓ mg/L-N Effluent stream concentration <br /> A 6.41,/ acres Site area <br /> Nb 1.00 ✓ mg/L-N Concentration of rain <br /> d 0.25 ,/ constant Denitrification factor <br /> inches per <br /> F <br /> R 4.17 / year Deep percolation of rain water <br /> inches per <br /> W 0.51 year Uniform waste water loading for calculation <br /> The details of the nitrate loading calculation are included in Plate 10. The results of the <br /> J <br /> 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 7.82 mg/L-N 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 from the use of septic systems in the ` I <br /> aquifer is predicted to be 7.82 mg/L-N. The result of the nitrate loading estimate is J <br /> below the maximum drinking water standard. <br /> LOGE1025 Page 11 <br />
