Nutrient pollution is one of America's most widespread, costly and challenging environmental problems and is caused by excess nitrogen and phosphorus in the air and water.
EPA has a website on nutrient pollution policy and data to help individuals access information on EPA actions to reduce nutrient pollution, state efforts to develop numeric nutrient criteria, and EPA tools, data, research, and reports related to nutrient pollution.

EPA also has a website on nutrient pollution for homeowners, students, and educators. The site features information explaining the problem of nutrient pollution; the sources of the pollution; how it affects the environment, economy, and public health; and what people can do to reduce the problem. The site also features an interactive map of local case studies in reducing nutrient pollution.
