What to Do if You Are Affected
If your area appears in this week’s digest, do not use unboiled tap water for drinking, cooking, brushing teeth, or preparing baby formula until the notice is officially lifted by your local water authority. Bring water to a rolling boil for one minute — three minutes if you are above 6,500 feet elevation — and allow it to cool before use. Commercially bottled water is a safe alternative for the duration of any active notice.
Monitor your local utility’s website for updates on when the notice will be lifted. You can also track all active US notices in real time on our live US boil water notice tracker, which is updated as notices are issued and cleared. For the latest water safety news nationwide, visit our water alert news section and our water quality database for detailed data on your local water system.
With thousands of boil water notices issued across the US every year, having a certified water filter at home provides protection that doesn’t depend on your utility’s infrastructure. See our water filter guide for independently tested and certified options, including NSF-certified reverse osmosis systems from Waterdrop.
