Explore EPA's Impaired Waters Data in ArcGIS Living Atlas of the World
Have you ever needed to perform a local water quality assessment?
Getting started with that process is now made easier by having the EPA Impaired Water Bodies dataset available in ArcGIS Living Atlas of the World.
Under Section 303(d) of the Clean Water Act, states and Tribes are required to assess and report water bodies that do not meet water quality standards. These hydrologic features are classified as impaired if they are affected by pollutants or conditions that limit their designated uses—such as drinking water supply, fish consumption, recreation, and more.
Each state or Tribe submits its assessments to the U.S. Environmental Protection Agency (EPA), and in many cases, they also develop restoration plans that include Total Maximum Daily Loads (TMDLs)—the maximum amount of a pollutant that a water body can receive while still meeting standards.
