This page tracks active alerts in one place, explains how advisories work in Ohio, and links the official state drinking water program you should double-check in an emergency.

In Ohio, boil water advisories are issued by the water system itself — a city utility, municipal authority, private company or rural water district — acting under rules enforced by Ohio EPA, Division of Drinking and Ground Waters. A notice is usually preventive — issued after a main break, pump failure or pressure loss — but it can also follow confirmed contamination in samples. Advisories are lifted only after repairs and two clean sample rounds are verified, which is why most last one to three days.

What to do when a Ohio advisory is issued
Follow the issuer’s instructions first. The standard playbook, aligned with CDC and Health Canada guidance: bring tap water to a rolling boil for one minute (three minutes above 2,000 m elevation) before drinking, preparing food, making ice or brushing teeth; throw away ice made before the advisory; sponge-bathe small children; and flush household pipes, ice makers and filters once the all-clear is announced.
