Nutrients Management Research
Excess nitrogen and phosphorus (nutrients) is among the most prevalent cause of water quality impairment in the United States. Research at EPA provides innovative solutions to address the problem of nutrient pollution in the Nation’s air, water and land. Researchers are:
- Studying the sources of nutrient pollution
- Determining where they go and how they move in the environment
- Evaluating the chemical changes that happen as they move in the environment
- Studying the effects on our environment and health
- Evaluating the benefits and costs associated with different nutrient management choices
How do we protect and sustain our water, land and air and protect our health while also providing the material, food, and energy required by society? To help answer this question, researchers are exploring solutions to:
- Reduce and control nutrient pollution
- Maximize efficient nutrient use
- Promote nutrient removal processes
- Protect people and natural resources
Much of this research supports the development of regulatory limits on nutrient pollution in water resources. At the same time, researchers work to understand the social and economic costs and benefits associated with potential solutions to excess nutrient problems so that optimal solutions for managing water quality over the long term can be achieved.
