ATTAINS - a Gateway to State-Reported Water Quality Information
Internet-based seminar
Hosted by EPA Office of Wetlands, Oceans, & Watersheds, Watershed Academy

EPA recently released a new Web site where water quality managers and the public can go to view a wide range of state-reported water quality information. This Web site, sometimes referred to as ATTAINS, combines two formerly separate databases: the National Assessment Database and the National Total Maximum Daily Load (TMDL) Tracking System. The National Assessment Database is for water quality assessment information reported by the states under Section 305(b) of the Clean Water Act, while the National TMDL Tracking System is for impaired waters information reported by the states under Section 303(d) of the Clean Water Act. ATTAINS gives the "full story" showing which waters have been assessed, which are impaired, and which are being (or have been) restored. This Web site allows the user to view dynamic, continuously updated tables and charts that summarize state-reported information for the nation as a whole, for individual states and waters, and for the ten EPA Regions.
