CALCULATED NITRATE-NITROGEN LOADING <br /> /wLS§ 3.3. The calculated nitrate-nitrogen impact to the soil and ultimately to the groundwater is <br /> diffic t-Yo quantify due to the number of variables involved. These variables include 1.) Variability <br /> in wastewater flows, nitrogen concentrations and dilution effects that may occur, 2.) Impact from <br /> previous on-site operations, 3.)Upgradient nitrate sources from agricultural farmland, 4.) Changes in <br /> groundwater directional flow and elevation, 5.) Denitrification potential of the underlying soil, and <br /> 5.) Rainfall and irrigation recharge. <br /> NLS§3.4,3.5,3.6.
