National Geospatial Program

Geospatial Applications

Below you will find EPA's publicly accessible applications. These applications have been developed to help the public access and visualize environmental information.

Air Quality Tools:

  • Air Quality Index (AQI) - AIRNOW
    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:

  • Better Assessment Science Integrating Point and Nonpoint Sources (BASINS)
    BASINS is a multi-purpose environmental analysis system for use by regional, state and local agencies in performing watershed and water quality based studies. It allows users to assess water quality at selected stream sites or throughout an entire watershed.

  • Watershed Assessment, Tracking & Environmental Results (WATERS)
    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:

  • Enforcement and Compliance History Online (ECHO
    Enforcement 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.

  • Envirofacts Data Warehouse
    This application 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.

  • EnviroMapper
    EnviroMapper 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.

  • EJView
    This tool allows users to conduct environmental justice assessments, or profiles, for a specified geographic area. EJView includes statistics pertinent to social, economic, health and environmental conditions.

  • My Environment 
    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.

  • NEPAssist
    NEPAssist 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:

  • Cleanups In My Community
    Use Cleanups in My Community 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:

  • EPA Metadata Editor (EME)
    The EPA Metadata Editor was developed to simplify and standardize geospatial metadata development across the Agency. It allows users to create and edit geospatial metadata records that meet the EPA Geospatial Metadata Technical Specification Version 1.0. and FGDC CSDGM requirements. Note: This software requires ArcGIS Desktop 9.2 with the .NET Support Feature and Microsoft .NET Framework 2.0.

  • Facility Registry System (FRS)
    The Facility 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.
