Mission: works to develop better ways to manage water pollution on a watershed-wide basis. By understanding how anthropogenic changes to upland environments result in specific identifiable stresses on receiving water bodies, appropriate management practices can be developed that will minimize the damage that these biological, physical and chemical stressors can cause. Focus areas for our research are point sources, such as Wastewater Treatment Plants and Concentrated Animal Feeding Operations (CAFOS), and non-point sources; such as land use and suburban development resulting in stressors such as nutrients, sediments, metals and other contaminants.Watershed
