Tap water in Guam

Generally safe to drink

The WHO and UNICEF put safely managed drinking water within reach of 100% of people in Guam. National figures describe a country, not the tap in front of you.

What the sources say

WHO / UNICEF JMP

100% of the population has safely managed drinking water, meaning it is free from contamination at the point of use.

US CDC Travelers' Health

Advises travellers that tap water is generally not safe to drink in Guam.

Numbeo

52.27/100 on the water drinkability and accessibility index, which Numbeo reads as “Moderate”. This one is crowdsourced from residents rather than measured.

Safe nationally still means ask locally. Older buildings can carry lead or copper pipework, and a single street can differ from the network feeding it. If you are staying somewhere old, ask your host.

What bottled water costs you here

Drinking tap water instead of bottled would save one adult about 1701$ a year in Guam, and keep several hundred plastic bottles out of circulation.
