CALCULATED NITRATE-NITROGEN LOADING NLS§3.3.%The calculated nitrate-nitrogen impact to the soil and ultimately to the groundwater is difficult to quantify due to the number of variables involved. These variables include 1.)Variability in wastewater flows, nitrogen concentrations and dilution effects that may occur, 2.) Upgradient nitrate sources from agricultural farmland, 3.) Changes in groundwater directional flow and elevation, 4.) Denitrification potential of the underlying soil, and 5.) Rainfall and irrigation recharge. NLS§_f4_,3.5,3.6.
