What the notices mean
Full guide →Boil water
Bring tap water to a rolling boil for one minute (three above 6,500 ft) before drinking, cooking, brushing teeth or making ice — or use bottled water.
Do not drink
Boiling won't make it safe — it can concentrate some contaminants. Use bottled water for drinking and cooking.
Do not use
Don't use tap water for anything, including bathing and washing. Follow your water system's instructions.
