Look up your water
Find the public water system serving your address. Enter your ZIP code; MyTapWater.us returns the utilities serving you, ranked by population served.
How it works
MyTapWater.us asks for your ZIP code only. We do not ask for your name, full street address, or anything else. Your ZIP is used once, in this session, to look up which public water systems serve the city and county your ZIP is in. The ZIP is not stored after your request finishes.
For each candidate utility, we link to a page showing what that system has measured for lead and copper, what violations EPA has on record, and how to reach the utility. Source data and verification are documented on the methodology page.
