EPA Region 8 Drinking Water Watch

Drinking Water Watch Logo

Drinking Water Watch is a tool that lets you view data we maintain about your water system(s). The information includes:

  • size and type of population served
  • water system facilities, such as wells, intakes, treatment plant, storage tanks, and distribution system
  • treatment used
  • sampling results reported to us,
  • violations, and
  • contact information.

Navigating within Drinking Water Watch is self-explanatory. If you have questions about terms, please click on the Glossary button. Feel free to call for assistance at (303) 312-6287 or contact us by email.

The Public Access Version of DWW (DWWPUB) allows anyone who is interested to view much of the available information for each regulated Public Water System (PWS) in Wyoming and within EPA R8 Tribal Lands.

In the restricted access version of Drinking Water Watch, we limit access to each system's data to registered users who work for the water system or who provide technical and program assistance to the system. We do this by requiring registered users to log in to DWW with unique user names and passwords. Unfortunately, due to recent changes to the user registration process, we are unable to support the registration of new DWW users.

Among many useful features, DWW users can generate ChemRad Sample Forms that are intended to aid in the collection of ChemRad samples and the reporting of lab results. These ChemRad Sample Form Instructions may be helpful to DWW users who wish to create ChemRad Sample Forms for their required monitoring.
