EPA Nitrogen and Phosphorus Pollution Website

EPA developed an improved website about nitrogen and phosphorus pollution to provide the public with information about this type of pollution—where it comes from, its impacts on human health and aquatic ecosystems, and actions that people can take to help reduce it. EPA's website also includes updated information on states' progress in developing numeric water quality criteria for nutrients as part of their water quality standards regulations. EPA recognizes that states and local communities are best positioned to restore and protect their waters, and the agency is providing technical guidance and tools to help states develop numeric nutrient criteria for their water bodies.

EPA Watershed Academy

EPA's Watershed Academy offers a variety of self-paced online training modules that represent a basic and broad introduction to the watershed management field. The modules are organized by six themes, and several address nutrient-related topics. The Watershed Academy also provides archived audio presentations, PowerPoint files, and other materials from webcasts conducted on nutrient-related topics.
