Data and Tools to Assist States, Tribes, & Territories

The U.S. Environmental Protection Agency has collected data, developed tools and supported the efforts of states, Tribes and territories to protect the nation’s water bodies from nutrient pollution as well as improve water quality. The combination of available tools and data not only helps water professionals better understand the distribution and effects of nutrient pollution, it also facilitates their modelling efforts geared towards reducing and managing the effects of such pollution on human health and the environment.

Learn about the data and tools available for better understanding the distribution, movement, and impacts of, and management options for, nutrients in surface and source waters (i.e., those used for drinking water and their contributing areas):
