EJSCREEN Resources

EJSCREEN is a tool that provide a great deal of information, based on data sources and methods that have been fully described in great detail in the EJSCREEN Technical Documentation, which is the most comprehensive source of information about EJSCREEN. For those simply wanting to learn how to start using the maps and reports, we have also provided a User Guide that walks through the steps involved. A fact sheet and list of common questions and answers are also available.

Other EPA Data and Mapping Tools

Below are links to a number of different data and mapping tools that have been developed by EPA. They may provide additional resources for screening and analyzing different areas for environmental and environmental justice concerns. EPA has created a comparison chart to explain key differences between commonly used mapping tools.

  • Cleanups in My Community (CIMC)

    CIMC enables you to map and list hazardous waste cleanup locations and grant areas, and drill down to details about those cleanups and grants and other, related information.

  • EnviroAtlas

    EnviroAtlas allows analysis of "what if?" scenarios and provides national to local scale data and analysis of the distribution of:

    • ecosystem services
    • benefits
    • stressors
    • drivers of change

  • Watershed Assessment, Tracking and Environmental Results System (WATERS)

    WATERS integrates water-related information by linking it to the NHDPlus stream network. The National Hydrography Dataset Plus (NHDPlus) provides the underlying geospatial hydrologic framework that supports a variety of network-based capabilities including upstream/downstream search and watershed delineation.

  • National Air Toxics Assessment (NATA)

    The National-Scale Air Toxics Assessment (NATA) is EPA's comprehensive evaluation of air toxics in the U.S. NATA is a screening tool that estimates cancer and noncancer risks based on chronic inhalation exposure to outdoor sources of air toxics. NATA is used to help prioritize areas that may need further study based on air toxics emissions, emission source types, and population risk. These assessments can help air pollution experts focus limited analytical resources on high-priority areas.

  • 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.

  • Risk-Screening Environmental Indicators (RSEI)

    The RSEI model is a computer-based screening tool developed by EPA that analyzes factors that may result in chronic human health risks. These factors include the amount of toxic chemical releases, the degree of toxicity and the size of the exposed population. RSEI analyzes these factors and calculates a numeric score. To give the score meaning, it must be ranked against other scores also produced by RSEI. The model highlights releases that pose the highest potential risk or potentially pose the highest risk. This way, RSEI helps policy makers and communities quickly identify situations that require further evaluation and set priorities for action.

  • Toxic Release Inventory (TRI)

    TRI tracks the management of certain toxic chemicals that may pose a threat to human health and the environment. U.S. facilities in different industry sectors must report annually how much of each chemical is released to the environment and/or managed through recycling, energy recovery and treatment. (A "release" of a chemical means that it is emitted to the air or water or placed in some type of land disposal.) The information submitted by facilities is compiled in the Toxics Release Inventory. TRI helps support informed decision-making by:

    • industry
    • government
    • non-governmental organizations
    • the public

State EJ Mapping Tools

Below are links to a number of different state environmental justice mapping tools. They may provide additional map layers and information not available at a national level or in the EJSCREEN tool. These tools are often at different resolutions and consider different datasets, so the results are not necessarily comparable.

  • CalEnviroScreen
    Developed by California’s Office of Environmental Health Hazard Assessment, CalEnviroScreen is a mapping tool that helps identify California communities that are most affected by many sources of pollution, and where people are often especially vulnerable to pollution’s effects. It uses environmental, health, and socioeconomic information to produce scores for every census tract in the state.
  • Colorado Demo EJ Map
    Mapping for Environmental Justice is a team of policy, data science, and community outreach experts aiming to increase the power of communities in ending environmental injustices. They developed an environmental justice map for Colorado, with additional state maps coming soon. The map displays the intersecting environmental, public health, and socioeconomic disparities experienced by low-income communities and communities of color, allowing users to identify disproportionately impacted communities. This cumulative impacts approach aggregates this information into a single indicator of cumulative environmental justice impact that paints a holistic picture of inequities.
  • Maryland Environmental Justice Screen Tool
    The Maryland Environmental Justice Screen Tool was developed to allow users to explore layers of environmental justice concern, determine the overall ‘EJ Score’ for census tracts in the state, and view additional context layers relevant to their area of concern or story they would like to tell. The tool combines the average pollution burden of a community with the average population demographic characteristics to produce an Environmental Justice (EJ) score. It was developed by the Community Engagement, Environmental Justice, and Health Laboratory at the University of Maryland School of Public Health.
  • DEQ North Carolina Community Mapping System
    The N.C. Department of Environmental Quality (DEQ) has created a department community mapping system, which is used to inform some department decisions, such as specific plans for local outreach and public participation. It provides permitting and other environmental information for the purpose of increasing knowledge, understanding, local outreach and public participation. It was developed to be an interactive tool that allows a variety of constituents to access important data about their communities.
  • Washington Environmental Health Disparities Map
    The Washington Environmental Health Disparities Map is an interactive mapping tool that compares communities across the state for environmental health disparities. It shows pollution measures such as diesel emissions and ozone, as well as proximity to hazardous waste sites. In addition, it displays measures like poverty and cardiovascular disease. The map also provides rigorous insights into where public investments can be prioritized to buffer environmental health impacts on Washington's communities, so that everyone can benefit from clean air, clean water, and a healthy environment. It was developed by the Washington State Department of Health.
