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.

For how our numbers are calculated, see the methodology; for the limits of our scores, see the disclaimer.
