Tap Water Safety in South America

South America's tap water quality tracks closely with infrastructure investment. Chile and Uruguay lead the continent with reliably safe urban water, and Argentina's major cities are largely safe. Elsewhere — Peru, Ecuador, and much of Colombia and Brazil — treatment at the plant is often undone by distribution problems, making bottled or filtered water the sensible default for travelers.
