Is Key West Tap Water Safe To Drink?
Yes! The tap water is safe to drink.
Yes, tap water in Key West is safe to drink for most people. The Florida Keys Aqueduct Authority supplies treated water from mainland Florida and monitors it to meet U.S. Environmental Protection Agency and Florida drinking water standards.
The water may sometimes have a chlorine taste or odor because disinfectant is used to protect it during transport through the long pipeline system. Letting water chill in a covered container can improve the taste without affecting its safety.
