We’d genuinely like to hear from you — especially if you’ve spotted something that looks wrong, know of an official data source we should add, or want to collaborate.
The best way to reach us is by email: hello@tapwaterissafe.com
What to write about
- Corrections — a score or fact that looks off. Please include the place and, if you can, a source.
- Data sources — official, government-grade drinking-water data for a country, state, or region we don’t yet cover in detail.
- Press & partnerships — media, research, or collaboration enquiries.
