Water can change locally
Water conditions can vary by city, building, island, rural area and temporary local advisory. Treat this page as general travel planning guidance and check local notices before relying on tap water.
“Not verified” can include useful local evidence without a destination-wide conclusion. Source review dates show when we checked the guidance; historical test results keep their original reporting period.
CDC guidance on food and water when travelling explains general precautions; it does not verify each country record in this list.

Reading country water guidance
Does a country summary cover every tap?
No. Water conditions can vary by locality, building and supply disruption. Follow current local notices and advice from your accommodation, especially after outages or severe weather.
What does an absent source or check date mean?
The record does not establish a recent verification. Treat it as limited background information and consult the local water supplier or health authority before relying on it.
What does an unknown status mean?
We have not verified a country-wide drinking-water classification. Unknown does not mean safe or unsafe. Check the water supplier or health authority for your actual address; a source about one city does not establish the situation nationwide.
Can boiling make any water safe?
No. Boiling can address germs, but it does not remove harmful chemicals. Follow the local water advisory and use a verified drinking-water supply when instructed.
