Learn how we collect and review tap water safety information using official government sources, public health data, and water authority reports.
Published on

Tap water safety information should be clear, accurate, and based on reliable sources.

All information on this website is based on publicly available data from:

  • Government water authorities
  • Municipal water providers
  • National public health departments
  • International health organisations

We review official water quality reports, safety standards, and public advisories where available.

We do not conduct independent water testing. Instead, we summarise official information to make it easier to understand.

Water safety can vary by region and can change over time due to infrastructure issues, natural events, or temporary advisories. For this reason, we aim to review and update information regularly.

This website is designed to provide a clear starting point for understanding tap water safety in different locations around the world.
