Sustainable Watersheds and Nutrient Pollution

Sediment runoff into the Mississippi River.EPA develops the models and tools needed to achieve sustainable solutions for managing nutrients in our watersheds – from freshwater streams to marine coastal environments.

Research Activites:

  • Identify the appropriate nutrient levels for waterbodies and use those levels as targets for resource protection and nutrient reductions.
  • Use new technologies to monitor nutrient levels and water quality.
  • Evaluate the public health and environmental effects originating from waters with excess nitrogen and phosphorus.
  • Predict how management decisions and future climate change impacts will alter nutrient levels and affect aquatic ecosystems.
  • Assess the effectiveness of a range of management practices for achieving sustainable reductions in nutrient pollution of water resources.
