The National Recommended Water Quality Criteria is a compilation of national recommended water quality criteria for the protection of aquatic life and human health in surface water for approximately 150 pollutants. These criteria provide guidance for states and tribes to use in adopting water quality standards.
This map shows the changes in stream water temperatures in the Chesapeake Bay region from 1960 to 2014. Blue circles represent cooling trends in stream water temperatures, and red circles represent warming trends in stream water temperatures. Data were analyzed by Mike Kolian of EPA in partnership with John Jastram and Karen Rice of the […]
Information on sole source aquifers (SSAs) is widely used in assessments under the National Environmental Policy Act and at the state and local level. A national layer, including all available SSA coverages, is available for use in GIS. This layer includes the GIS polygons for SSAs. In addition to single SSA designated area polygons, some […]
SDWIS/State is a data system that EPA is developing for states that will improve the quality of drinking water information.
