Boil Water Advisory: What to Do

During a Boil Water Advisory, it’s essential to take extra precautions to keep yourself and your family safe. This section provides simple steps for using and storing water safely, along with tips for washing hands, handling food, and even bathing. Follow these guidelines to ensure your water is safe for drinking, cooking, and everyday use.

Important: Boil All Water for Drinking and Cooking
During a Boil Water Advisory, boil tap water for at least one minute before using it for any consumption purposes. Only start timing after the water reaches a full rolling boil.

Uses Requiring Boiled Water

  • Drinking
  • Preparing baby food, formula, or juices
  • Making ice
  • Washing fruits and vegetables
  • Brushing teeth

Washing Produce
Only use boiled or bottled water to wash fruits and vegetables that won’t be cooked.

Handwashing Tips

  • Wash hands with soap and running water, especially after using the restroom, handling pets, or before preparing food.
  • After washing and drying, use a 60% alcohol-based hand sanitizer, ensuring it fully dries to disinfect.

After boiling, cool the water and store it in a clean, sanitized container with a lid. To sanitize, wash the container in a solution of 1 gallon of water mixed with ¼ cup of bleach. Avoid drinking or consuming this cleaning solution.

  • Adults may shower with untreated water but should avoid swallowing any.
  • Young children should use a sponge bath instead of a tub bath to minimize contact.
