For your water, start locally

Check an active advisory.

Tap Water Lookup does not track live local emergencies. Historical measurements cannot confirm whether an advisory is in effect today.

01 / Your utility

Go to the service-area source.

Use the utility name on your water bill to find its official website, notices, and customer service line. Check that an advisory applies to your address and follow the instructions in that notice.

02 / Your state or territory

Find your drinking-water agency.

EPA’s directory links to state, territorial, and Tribal drinking-water programs and available public databases. Local public health departments may also publish advisory information.

A briefing that follows your interests

Choose what reaches your inbox.

National research, policy, and funding updates, with the original sources. Email briefings do not replace your utility’s emergency notification service.
