Yes, Portland’s tap water is safe to drink. Most of the city’s tap water comes from rainfall collected in the Bull Run watershed, a drainage basin located 30 miles (48 km) east of Portland. Bull Run water isn’t filtered (though a new filtration system is being installed and is expected to start filtering Bull Run water by 2027), but chlorine is added to the water to disinfect it of any potential natural contaminants.
