What Should I do?
- Use bottled or boiled water for drinking, and to prepare and cook food.
- If bottled water is not available, bring water to a full rolling boil for 1 minute (at elevations above 6,500 feet, boil for 3 minutes). After boiling, allow the water to cool before use.
- Boil tap water even if it is filtered (for example, by a home water filter or a pitcher that filters water).
- Do not use water from any appliance connected to your water line, such as ice and water from a refrigerator.
- Breastfeeding is the best infant feeding option. If you formula feed your child, provide ready-to-use formula, if possible.
- In many cases, you can use tap water and soap to wash hands during a boil water advisory. Follow the guidance from your local public health officials.
- Be sure to scrub your hands with soap and water for at least 20 seconds. Then, rinse them well under running water.
- If soap and water are not available, use an alcohol-based hand sanitizer that contains at least 60% alcohol.
- Be careful not to swallow any water when bathing or showering.
