LOGE 1946: Cain NLS Addendum Page 2 <br /> March 10, 2020 <br /> Table 1. Inputs and Results for Nitrate Loading Calculation, <br /> Wastewater Flow Calculated by March 2020 Method <br /> Variable Value Units Description <br /> Q 400 gpd Effluent flow rate <br /> Nw 35 mg/L-N Effluent stream concentration <br /> A 2.25 acres Site area <br /> Nb 0.3 mg/L-N Concentration of rain <br /> d 0.35 constant Denitrification factor <br /> R 3.68 inches per year Recharge rate of rainfall <br /> W 2.4 inches per year Uniform waste water loading (calculated) <br /> Nc 9.1 mg/L-N Long-term average concentration of percolating effluent <br /> For this Site, the long-term average concentration of percolating effluent is found to be <br /> 9.1 mg/L-N when calculated as shown. This value is below the US EPA recommended <br /> MCL for nitrate in drinking water of 10 mg/L-N. The nitrate loading calculation is <br /> attached. <br /> It has also been brought to our attention that there is an error on page 3 of the report, in <br /> the section titled "On-Site Wells." One domestic well is located on the Site, as depicted <br /> in Plate 2 of the original report. <br /> Please feel free to contact us with any questions about this project. <br /> Sincerely, <br /> Live Oak GeoEnvironmental, Inc. <br /> r _ <br /> S\nNA Fp\ <br /> Abigail Racco, Project Manager DAVID J.MELCH -A <br /> N0.2151 <br /> r ( CERTIFIED ! <br /> MINEERING <br /> GEOLOGIST <br /> David J.
