Many other applications make use of data from Water Quality Portal web services. This is a partial list.  If you know of an application that uses Water Quality Portal data or services, please let us know so that we can add it to this list.

  • EPA Data Discovery Tool: EPA's Data Discovery tool was developed to help users find, filter, view, and prepare data for analysis using data from the Water Quality Portal. The tool was built in R Shiny and can run on Windows and Mac.  
  • Delaware Water Quality Portal: The Delaware Water Quality Portal presents water quality data collected by Delaware Department of Natural Resources and Environmental Control (DNREC) Surface Water Quality Monitoring Program.
  • EPA Nitrogen and Phosphorus Pollution Data Access ToolEPA’s “Nitrogen and Phosphorus Pollution Data Access Tool” (NPDAT) helps states, other partners, and stakeholders to:
    • Prioritize watersheds on a statewide basis for nitrogen and phosphorus loading reductions.

    • Set watershed load reduction goals based upon best available information.
