The nitrate concentration of rain fall was estimated to be 1 mg/L-N (Hantzsche <br />and Finnemore, 1992). <br />5.3 Current On-Site Sources of Nitrate <br />The current onsite 4-bedroom residence, and associated septic system and rainfall are <br />recognized as potential current on-site sources of nitrate. <br />5.4 Future On-Site Sources of Nitrate <br />5.4.1 Quantity and Quality of Domestic Wastewater from Proposed Project <br />The following discussion is for determining the long-term wastewater flow anticipated from <br />the planned residential house for the site, to be incorporated into the nitrate loading analysis. <br />The anticipated wastewater flow determined is not intended to be used for septic system <br />design, because septic system sizing includes a peak use factor, whereas the numbers <br />discussed herein are based on a long-term conservative measure of estimated effluent <br />volume. <br />4-bedroom residence with associated septic system onsite.
