Nutrients Management Research
Excess nutrients (nitrogen and phosphorus) are among the most prevalent cause of water quality impairment in the United States. To make our water, land and air sustainable and to protect our health while also providing the material, food, and energy required by society, EPA's researchers are exploring solutions to
- reduce and control nutrient pollution and harmful algal blooms,
- maximize efficient nutrient use,
- promote nutrient removal processes, and
- protect people and natural resources.
EPA's research provides innovative solutions to address the problem of nutrient pollution. Below are some examples of research areas being studied at EPA:
- Sources of nutrient pollution
- Harmful algal blooms
- Fate and transport of nutrients in the environment
- Chemical changes that happen as nutrients move in the environment
- Effects of nutrient pollution on our environment and health
- Benefits and costs associated with different nutrient management choices
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.
