How does EPA use Geographic Information Systems in its work? Does EPA have GIS data available online?

Much of EPA's geospatial data is available from EPA's National Geospatial Program home page at http://www.epa.gov/geospatial/.  For additional information about EPA’s GIS data, please contact the Geospatial Program: http://www.epa.gov/geospatial/contact.html.

Several EPA Regional websites have information about how GIS data is used specifically in the region. Some are listed on the National Geospatial Program website (above) and also here:

EPA Region 2 GIS: http://www.epa.gov/region02/gis/
EPA Region 3 GIS:

EPA Region 6 GIS:

EPA Region 7 GIS:

EPA is currently using GIS for the following activities:

-Environmental Justice Applications
-Risk Assessment
-Superfund Site Assessment
-CBEP Projects
-Total Maximum Daily Load for streams (TMDL)
-Track pollutant distribution
-Identify threatened/endangered species in watersheds
-R-EMAP: Regional Environmental Monitoring & Assessment Program: Regional scale analyses of water quality and fishery health


EPA's has developed publicly accessible applications to help the public access and visualize environmental information. You can explore these applications at the following Web page:      http://www.epa.gov/geospatial/tools.html

To find EPA's geospatial data you can visit EPA's Environmental Dataset Gateway (EDG). The EDG is a gateway to Web-based geospatial information and information services. It enables data consumers to discover, view and access geospatial resources (e.g., data, services, or applications) made available by EPA's program offices, regions, and labs.

You can search EPA's Environmental Dataset Gateway at the following Web page: http://www.epa.gov/geospatial/data.html
