a Boil Water Advisory?
Local departments and state or local agencies issue drinking water advisories when they believe water quality is or may be compromised. Advisories tell individuals, schools, hospitals, businesses, and others about the situation and how to take immediate action.
When is a Boil Water Advisory recommended?
Boil Water Advisories are issued when there is known contamination of the water supply or when there is a risk of contamination of the water supply.
What is the proper way to disinfect my water so it is safe to drink?
The best treatment method is boiling. Boiling water kills harmful bacteria, viruses, and parasites (freezing will not disinfect water).
- Bring water to a full rolling boil for at least 1 minute to kill most infectious organisms (germs).
For areas without power, disinfect tap water by adding 8 drops (about 1/8 teaspoon) of plain unscented household bleach to a gallon of water.
- Thoroughly mix the solution and allow the water to stand for 30 minutes.
- If the water is cloudy, repeat the process.
- Use a container with a cap or cover for disinfecting and storing water to be used for drinking. This will prevent re-contamination.
How long is boiled water safe to drink?
As long as the water container is protected with a cap or a cover, it remains safe to drink.
How will I know when the Boil Water Advisory has been lifted?
The community will be notified when the water is safe to drink without boiling. It will be communicated through social media channels, local media (TV & Radio), institutions (schools, hospitals), restaurants, and community centers. Contact your local public works office with questions and inquiries.
What do I do after the Advisory has been lifted?
- Turn on your tap slowly and run the water to flush water pipes for five minutes.
- You may need to clean appliances such as water softeners, filter units, water dispensers and ice makers. Read the owner's manual for directions to clean appliances.
