How the lookup works
- Search your city, ZIP code or water utility.
- Open your utility's page to see its lead, galvanized and unknown service line counts, lead test results and violation history.
- Check your exact address on the utility's official inventory map, linked from its page.
- Confirm at home with the 2-minute scratch and magnet test.
Reading your results
- Lead and galvanized requiring replacement: must be replaced; most systems face a December 31, 2037 deadline.

Common questions
How do I find out if my house has lead pipes?
Search your city, ZIP code or water utility above to see what your utility reported, then open its address-level service line inventory. Every U.S. water system had to prepare one by October 16, 2024. You can also scratch-test the pipe where water enters your home.
Can I look up lead pipes by address?
Address-level records are held by each water utility. Lead Pipe Map finds your utility and links to its official inventory or contact details, where you can search your exact address.
Is the lookup free?
Yes. Lead Pipe Map is free and uses public EPA data.
What do the results mean?
"Lead" and "galvanized requiring replacement" lines need to be replaced. "Unknown" lines have not been identified yet and should be treated as possibly lead until checked.
