About Boil Water Notices and Advisories:

Boil water advisories are issues when there could be something in your water systems that makes it unsafe. Drinking the water without boiling it can make you very sick. Boiling your water makes it safe to drink.

If there is a boil water notice or advisory, you should boil your water or use bottled water when cooking, washing fruits and vegetables, brushing your teeth, or making baby formula. You should also use boiled water to wash your hands when cooking. Adults and older children do not need to use boiled water to shower or bathe, but you should try not to swallow any water or get any water into your mouth. Infants, toddlers, the elderly, and people with severely compromised immune systems should be bathed using boiled or bottled water.
How to Boil Your Water So it is Safe to Use
You can safely boil your water by bringing it to a rolling boil for one minute. A rolling boil means that there are very large bubbles in the water, making the water move very quickly. Make sure the water does not have any floating pieces in it before you boil it.
