Best Practices for Boiling Water

To ensure you are consuming safe water during a boil water advisory, follow these best practices:

  • Boiling Method: Bring water to a rolling boil for at least one minute. If you are at elevations above 2,000 meters (6,562 feet), boil for three minutes.
  • Cooling: Allow the water to cool before use. You can also fill clean containers for future use.
  • Storage: Store boiled water in clean, sanitized containers to prevent re-contamination.
  • Filter Applications: If you have a water filter, ensure it is suitable for all contaminant types, as not all filters can purify compromised water.

Implementing these practices helps ensure your drinking water is safe and free from potential pathogens.
