Groundwater Modeling of Nitrates

Modeling Fate and Transport of Nitrates from Septic Systems, Sewage Effluent, and Agricultural Practices

Nitrate groundwater contamination can originate from a variety of sources including septic system, untreated raw sewage effluent, and agricultural application of fertilizers and pesticides. Visual MODFLOW is commonly used for modeling the fate of nitrates in groundwater. Various approaches can be used, but the most common use a version of MODFLOW (2005 or NWT) and MT3DMS.
