We've made some changes to EPA.gov. If the information you are looking for is not here, you may be able to find it on the EPA Web Archive or the January 19, 2017 Web Snapshot.


Status of EnviroAtlas

Current Status

EnviroAtlas has been publicly available since May 2014 (News Release, May 7, 2014). Development plans for EnviroAtlas extend out to 2019, with regular updates taking place as they become available. View the EnviroAtlas Dynamic Data Matrix to search and sort through a list of currently available EnviroAtlas data.  

Latest Updates to EnviroAtlas 

  • Released June 28, 2017. The new EnviroAtlas Interactive Map is easier to use, includes new analysis tools, and has improved performance and speed. 
  • Newest communities: Cleveland, OH and Minneapolis / St. Paul, MN 
  • New Data: Impaired Waters maps for the contiguous U.S. 
    • Stream length impaired by mercury (km)
    • Stream length impaired by metals other than mercury (km) 
    • Stream length impaired by nuisance species (km)
    • Stream length impaired by nutrients (km)
    • Stream length impaired by organic enrichment or oxygen depletion (km)
    • Stream length impaired by pathogens (km)
    • Stream length impaired by pesticides (km)
    • Stream length impaired by pH, acidity, or caustic conditions (km)
    • Stream length impaired by sediment or turbidity (km)
    • Stream length impaired for temperature (km)
  • ​New Data: Recreation demand maps for the contiguous U.S. 
    • Big game hunting recreation demand
    • Bird watching recreation demand
    • Freshwater fishing recreation demand
    • Migratory bird hunting recreation demand 
  • ​New Data: National map showing approximate acres of land within each sub-watershed (12-digit HUC) enrolled in the US Department of Agriculture's (USDA) Conservation Reserve Program (CRP), summarized by 12-digit-HUC.  
  • Tool Update: The Eco-Health Relationship Browser has been updated with evidence from the literature through 2014. The update to include relevant literature published in 2015 and 2016 is also underway.

Planned Updates

A selection of planned improvements, with the projected completion dates in parentheses, is below.


  • New communities, including  New Haven, CT; Baltimore, MD; Birmingham, AL; and Norfolk/VA Beach, VA (2017). Additional communities will be added yearly, with the goal of over 50 communities by 2019.
  • Maps of future scenarios based on land use/land cover projection data and future climate scenario projections (2017).
  • Additional Use Cases that provide descriptive examples of how to use EnviroAtlas data (Ongoing). 

Analysis Tools

  • The ability to graph or analyze the relationship between selected map layers for selected 12-digit HUCs or census block groups (2017).
  • In a statistically robust manner, combine multiple data attributes into single index values that can be used in various analyses, visualization, and graphing tools. Allows user control over variable weighting (2017).
  • A tool to allow the user to calculate metrics for any spatial unit of interest (2018).


  • Simultaneously view two maps that can be spatially synchronized (2017).
  • Create a user profile that will allow you to upload your own data, save map sessions, and create bookmarks for specific areas (2017).
  • Search for specific map layers (2017).
  • The ability to select an area by drawing a box or by clicking on a spatial unit (e.g., county, state, watershed, census block group) and analyze or download user-selected data (2017).
  • The ability to select spatial units by attribute (e.g., selecting all census block groups with high population over 65) and analyze or download user-selected data (2017).

As the project progresses, this webpage will be updated with the latest news on EnviroAtlas.
