Is San Juan Tap Water Safe To Drink?
Yes! The tap water is safe to drink.
Tap water in San Juan, Argentina, is generally treated and safe to drink when it comes from the public water network. The provincial water utility, OSSE, monitors and treats water according to national drinking-water standards.
Water quality can vary in rural areas or properties using private wells, where treatment and maintenance may differ. If the water looks cloudy, has an unusual odor, or follows a local service interruption, use bottled or boiled water until the supply returns to normal.

San Juan Drinking Fountains
Public drinking fountains in San Juan are generally safe when connected to the municipal drinking-water system, which is regulated under U.S. federal drinking-water standards. Water quality can still vary if a fountain is poorly maintained, damaged, or temporarily affected by a service advisory.
Use fountains that are clean and functioning properly, and avoid any marked as out of service or showing cloudy water, unusual color, or odor. Let the water run briefly before drinking, especially after the fountain has not been used for some time.
