Displaying Water Quality Standards Information Using Web-based GIS: A Foundation for Water Quality Management
The EPA Office of Water is developing data systems that will enable EPA, States, Tribes, and the public to view water quality standards for the surface waters of the United States on the Internet. Water quality standards have been available as parts of detailed State regulations in text form (U.S. EPA, 1999). Since May 1998, the Water Quality Standards Branch of the Office of Science and Technology (OST), in coordination with other EPA offices, has been developing detailed geographic information system (GIS) coverages of waters and their water quality standards, as well as a national Water Quality Standards Database (WQSDB). These products will allow for the display and spatial analysis of water quality standards information. A complete picture of the locations of waters and their standards will help EPA and State and local governments target their management resources more effectively, and will increase and enhance public access to environmental information.
