Disclaimer

Boil Water Alerts is an independent aggregator of publicly available information about drinking water advisories. It is not a government agency and is not affiliated with, endorsed by, or authorized by any utility, municipality, state, province or federal agency in the United States or Canada.

Accuracy and timeliness

We reproduce and link to data published by official sources. Government feeds can lag real events, contain errors, or change without notice. We make no warranty, express or implied, about the completeness, accuracy, reliability or availability of the information on this site, and we may not display every advisory in effect at any moment.

Not official notice

Nothing on this site constitutes an official notice to you under any drinking water regulation. Only the issuer of an advisory — your water system, local health department or state/provincial authority — provides binding notice and instructions. If this site and an official source disagree, the official source controls.

Health guidance

Our guidance pages summarize general recommendations aligned with public health agencies such as the CDC, EPA and Health Canada. They are general information, not medical advice, and cannot account for your specific circumstances. Follow the instructions in the actual advisory and contact a health professional for medical questions.

Data licensing note

Content originating from government sources remains subject to the licensing terms of its publisher. Where a source requires attribution, we provide the source name and a link on every notice we display.
