The management framework utilizes models of nitrate fate and transport in the unsaturated and saturated zones to simulate nitrate concentration at the critical receptors. To study the impact of different management options considering both environmental and economic aspects, concentrations in groundwater due to the accumulation of animal waste and subsequent seepage into the groundwater system (Becker et al. 2001, Panno et al. 2005). Other potential sources of contamination include agricultural runoff, mine drainage, salt-water intrusion, and industrial discharge (Kim et al. 2015, Panno et al. 2005).
