Geospatial Resources at EPA

EPA Geospatial Applications

EPA has developed many applications that allow users to explore and interact with geospatial data. This page highlights some of the flagship geospatial web applications but these represent only a fraction of the total. We recommend EPA’s Environmental Dataset Gateway and Developer Central as the best tools to help connect you with an application that best meets your needs.

Air Quality Tools:

Link to AirNowAir Quality Index (AQI) - AIRNOW provides the Air Quality Index (AQI) forecasts as well as real-time AQI conditions for over 300 cities across the US. Also, the application provides links to more detailed state and local air quality Web sites.

Water Quality Tools:

Link to BeaconBeach Advisory and Closing Online Notification (BEACON) is a system designed to meet the Agency's requirement to provide to the public a database of pollution occurrences for coastal recreation waters.

Link to WatersWatershed Assessment, Tracking & Environmental Results (WATERS) is an integrated information system for the nation's surface waters. Under WATERS, the EPA Office of Water program databases are connected to a larger framework known as the National Hydrography Dataset (NHD). By linking to the NHD, one program database can connect to another, and information can be shared across programs.

Learn about the Environment in your Neighborhood:

Link to ECHOEnforcement and Compliance History Online (ECHO) is used to determine whether compliance inspections have been conducted by EPA or state/local governments. It also shows whether enforcement actions were taken and penalties were assessed in response to environmental law violations.

Link to EnvirofactsEnvirofacts Data Warehouse is an application that allows users to access several EPA databases in order to view information about environmental activities that may affect air, water and land anywhere in the United States. Envirofacts allows users to learn about environmental activities in their area or generate maps of environmental information.

Link to EnviromapperEnviroMapper is a tool that allows users to map various types of environmental information, including air releases, drinking water, toxic releases, hazardous wastes, water discharge permits and Superfund sites. Maps can be created at the national, state and county levels, and linked to environmental text reports.

EJScreenThumbnail EJSCREEN is an environmental justice mapping and screening tool that provides EPA with a nationally consistent dataset and approach for combining environmental and demographic indicators.

Link to MyEnvironment My Environment is a web-based tool that features a wide range of information about environmental conditions in an area of your choice. This tool integrates EPA and other resources through a single mash-up display of environmental information, e.g. MyAir, MyWater, MyHealth.

Link to NEPAssistNEPAssist is a tool that facilitates the environmental review process and project planning in relation to environmental considerations. The web-based application draws environmental data dynamically from EPA's Geographic Information System databases and web services and provides immediate screening of environmental assessment indicators for a user-defined area of interest. These features contribute to a streamlined review process that potentially raises important environmental issues at the earliest stages of project development.

Waste Management Tools:

Link to Cleanups in my communityCleanups In My Community is used to map and list areas where pollution is being or has been cleaned up throughout the United States. Find your community and drill down to cleanup specifics about: Sites, facilities and properties under EPA's Superfund, RCRA and/or Brownfields cleanup programs or Federal facilities under EPA's Superfund and/or RCRA cleanup programs. You can also add tribal lands, Brownfields grant areas and water monitoring stations to your map, and drill down to further information about grants and water quality.

Other Tools and Resources:

Link to FRSFacility Registry System (FRS) is a centrally managed database that identifies facilities, sites or places subject to environmental regulations or of environmental interest. FRS creates high-quality, accurate, and authoritative facility identification records through rigorous verification and management procedures that incorporate information from program national systems, state master facility records, data collected from EPA's Central Data Exchange registrations and data management personnel. The FRS provides Internet access to a single integrated source of comprehensive (air, water, and waste) environmental information about facilities, sites or places.  

EME ThumbnailThe EPA Metadata Editor (EME) is a custom software tool that aids the practical documentation of geospatial datasets. EME v5.0 assists GIS professionals in creating, editing, and validating metadata that complies with EPA’s Metadata Technical Specification, ISO’s 19115 standard endorsed by the Federal Geographic Data Committee (FGDC), and OMB’s Project Open Data (POD) schema. EME v5.0 is EPA’s customization of Esri’s ArcCatalog metadata editor and creates ISO/POD-compliant ArcGIS Metadata.
