Water Source
Municipal water is treated at the source, but distribution infrastructure and low pressure allow contamination to enter before it reaches the tap, consistent with the rest of Mexico.
Contaminants & Concerns
Bacterial contamination from aging pipes is the primary concern; travelers' diarrhea linked to tap water and ice is common.
Tips
- •Resorts and hotels provide bottled or purified water — use it exclusively
- •Avoid ice unless you know it was made from purified water
