Date | Type | Title | Description | Link (if available) |
---|---|---|---|---|
06/2023 | New Data | Animal Feeding Operations (AFOs) data | Summarizes numbers of animals and Animal Feeding Operations (AFOs) by type and county | https://enviroatlas.epa.gov/enviroatlas/interactivemap/?eaLayer=eaLyrNum_414 |
10/2023 | Updated Data | Assessed and Impaired Water Areas | Combines impaired and assessed waters and allows user to specify the type of geography they would like to display | https://enviroatlas.epa.gov/enviroatlas/interactivemap/?eaLayer=eaLyrNum_447 |
01/2023 | New Tool | Summarize My Area Tool | The tool, denoted as the sigma symbol, allows users to calculate landscape characteristic metrics for any area of interest using current or historic land cover or land cover change statistics | https://enviroatlas.epa.gov/enviroatlas/interactivemap/ |
10/2023 | New Data | Stream Confluence Catchments and Watershed | National dataset which classifies a waterbody's ability to function on a scale of "poor" to "good" | https://enviroatlas.epa.gov/enviroatlas/interactivemap/?eaLayer=eaLyrNum_411 |
07/2023 | Updated Toolbox |
Dasymetric Toolbox |
Allows users to more accurately distribute population data that has been assigned to arbitrary boundaries, such as census blocks | https://www.epa.gov/enviroatlas/dasymetric-toolbox |
07/2023 | Updated Data | Dasymetric Allocation of Population | Data recalculated for 2010 and new data added for 2020. Improved analyses allow a more accurate representation of population density. | https://enviroatlas.epa.gov/enviroatlas/interactivemap/?eaLayer=eaLyrNum_714 |
05/2023 | Updated Toolbox |
Analytical Tools Interface for Landscape Assessments (ATtILA) |
New tools and functionality were added and allows users to calculate many of the EnviroAtlas metrics faster and reduce the chance of errors | https://www.epa.gov/enviroatlas/attila-toolbox |
05/2023 | Updated Data | Nitrate violation index - Groundwater | Data added for missing 12-digit HUCs | https://enviroatlas.epa.gov/enviroatlas/interactivemap/?eaLayer=eaLyrNum_403 |
05/2023 | Updated Data | Nitrate violation index - Surface water | Data added for missing 12-digit HUCs | https://enviroatlas.epa.gov/enviroatlas/interactivemap/?eaLayer=eaLyrNum_404 |
03/2023 | New Data | Total Evapotranspiration (m/yr) | Estimates the average annual evapotranspiration rate in meters/year across each subwatershed (12-digit HUC) for 2000-2013 | https://enviroatlas.epa.gov/enviroatlas/interactivemap/?eaLayer=eaLyrNum_437 |
03/2023 | New Data | Surface runoff - (Quick flow ) (m/yr) | Estimates the average quick-flow surface runoff from precipitation in meters per year across each subwatershed (12-digit HUC) for 2000-2013 | https://enviroatlas.epa.gov/enviroatlas/interactivemap/?eaLayer=eaLyrNum_438 |
03/2023 | New Data | Simulated depth to water table (m) | Estimates the average depth to the water table in meters across each subwatershed (12-digit HUC). The map reflects simulated natural conditions without withdrawals. | https://enviroatlas.epa.gov/enviroatlas/interactivemap/?eaLayer=eaLyrNum_439 |
03/2023 | New Data | Unsaturated zone water transit time (yrs) | This map estimates the average travel time of a solute in water across the unsaturated zone (the area between the surface and the water table) in years by subwatershed (12-digit HUC); this represents the time it takes for a solute to travel from the land surface to the water table. | https://enviroatlas.epa.gov/enviroatlas/interactivemap/?eaLayer=eaLyrNum_440 |
