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.
