Total nitrogen concentration of influent waste stream is 35 mg/L-N. If different influent concentrations exist, use weighted average <br /> 2. Fraction of nitrate-N loss due to denitrification in the soil is 35%. <br /> 3. Estimated deep percolation of rainfall is 3.86 in/yr. <br /> 4. Background nitrate-N concentration of rainfall is 0.3 mg/L-N. <br /> LOGE 20-22 July 6, 2020 <br />
