Is San Rafael Tap Water Safe To Drink?
Yes! The tap water is safe to drink.
Tap water from the public supply in San Rafael, Mendoza, is generally safe to drink and is treated under Argentina’s drinking-water standards. It may have a noticeable mineral or chlorine taste, but this does not usually indicate a health risk.
Water from private wells, rural systems, or storage tanks may not receive the same treatment or testing. For those sources, use bottled or properly filtered water unless recent testing confirms it is potable.

Source of Water in San Rafael, Argentina
