Total nitrogen concentration of influent waste stream is 45.6 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 25%. <br /> 3. Estimated deep percolation of rainfall is 12.9 in/yr. <br /> 4. Background nitrate-N concentration of rainfall is 1 mg/L-N. <br /> Plate No.: 11 <br /> Nitrate Loading Calculation <br /> 4wo Project No: 1841 <br /> Block 21 Winery Date: November 15,2018 <br /> LIVE OAK 21600 N.Davis Rd. <br /> GEO ENVIRONMENTAL INC.
