Is the tap water safe to drink in Iceland?
Yes, from the cold tap. WHO and UNICEF put safely managed drinking water in Iceland at 100% for 2024, and in the capital area the cold tap water is spring water from protected catchments.
What the official figures say
Hot water comes from a separate geothermal district heating system, drawn from wells and power plants to heat buildings. For drinking and filling bottles, always use the cold tap.
Why a public tap can still be different
Outside the towns you'll pass rivers, streams and springs. Glacial rivers carry silt, and streams near grazing land can be contaminated even when the water looks perfectly clear.
Check the tap, then tell the next person
Use the taps at campsites, trailheads and service stations, and check the spout first. When you find one, add it to Fontavio or review it; it helps people plan their refills before a long drive.
