Last week, EPA released the Watershed Assessment, Tracking and Environmental Results (WATERS) integration web site. WATERS unites geographically specific water quality data from state web sites and various EPA sites, including EPA's new National Water Quality Standards Database and its Total
Maximum Daily Loads (TMDL) Database, with the US Geological Survey's National Hydrographic Dataset. WATERS users can click on an interactive map to see which waters are classified by states as impaired (those waters not attaining water quality standards), and to learn the purpose or use of each waterbody
(such as whether or not it is designated for protection as a drinking water supply, for recreational use, or for fishing). Although not yet complete, WATERS will eventually cover all 50 states, and contain links to data on ambient water quality, drinking water quality, polluted runoff, fish consumption advisories, facility discharge outfalls, and other information.
