EPA’s online mapping tool enables water professionals to protect source water

March 5, 2020

The U.S. Environmental Protection Agency is providing Drinking Water Mapping Application to Protect Source Waters (DWMAPS), an online mapping tool, to help state and utility drinking water professionals update their source water assessments and protection plans in concert with other state and local mapping tools.

It can be useful for groundwater protection purposes. Specifically, DWMAPS helps users:

  • Identify potential sources of contamination in locations defined by users
  • Find data to support source water assessments and plans to manage potential sources of contamination
  • Evaluate accidental spills and releases, identifying where emergency response resources for accidental releases must be readily available
  • Promote integration of drinking water protection activities with other environmental programs at the EPA, state, and local levels.

Please note DWMAPS does not display the actual locations of public water system facility intakes but contains a wide variety of data useful to protection of drinking water sources.
