Yes, you can safely drink the tap water in Key West and throughout the Florida Keys in 2026. The water is provided by the Florida Keys Aqueduct Authority (FKAA) and consistently meets or exceeds all EPA and state health standards. The water primarily comes from the Biscayne Aquifer on the mainland near Florida City and is pumped 130 miles through a massive pipeline to reach the islands. To ensure safety, the FKAA utilizes advanced treatment processes, including lime softening and reverse osmosis, and adds chloramines for long-lasting disinfection. While the water is safe, some visitors may notice a slightly different mineral taste compared to their home supply, but it is high-quality, potable water suitable for drinking, cooking, and ice-making.
