Return to Nonpoint Source Pollution: Nutrients

This image is an aerial view along the Fox River in Wisconsin. Nitrogen and phosphorus that come from smokestacks and combustible sources, such as automobiles, are significant sources of nutrients that end up in waterbodies and can lead to eutrophic conditions. Controlling atmospheric nutrient inputs is proving to be a challenge because their sources are difficult to identify.
