Is St Croix Tap Water Safe To Drink?
No, it's not advisable to drink the tap water.
Tap water in St. Croix is generally safe to drink when it comes from the Virgin Islands Water and Power Authority (WAPA) public supply and no boil-water advisory is in effect. The system is regulated under U.S. drinking-water standards and treated before distribution.
Many St. Croix homes also use rainwater cisterns, which are not automatically safe to drink and may contain bacteria, sediment, or contaminants from roofs and storage tanks. Cistern water should be properly filtered, disinfected, and tested before consumption.

Source of Water in St Croix,
Tap water in St. Croix comes mainly from groundwater drawn from wells. The Virgin Islands Water and Power Authority treats and distributes this water through the public supply system.
Reverse-osmosis desalination supplements the island’s groundwater supply, especially when demand is high or wells are limited. Many homes also collect rainwater in cisterns, which is separate from the public tap-water system.
St Croix Drinking Fountains
Public drinking fountains in St. Croix are generally safe to use when they are connected to the island’s regulated public water system and properly maintained. The water must meet U.S. drinking water standards, but individual fountains can become contaminated if dirty, damaged, or poorly maintained.
Use fountains that appear clean and functional, and follow any posted boil-water or drinking-water advisories. Avoid using a fountain with cloudy water, unusual odor, visible damage, or poor sanitation around the spout.
