New Jersey
New Jersey requires public community water systems to inventory service lines, notify residents, and replace all lead service lines by July 22, 2031. NJDEP also publishes a statewide Potential Lead Exposure Mapping tool with summarized utility inventory data, but homeowners usually need their own utility’s page to enroll in a replacement program.

What to do next
- Check the NJDEP map first to identify your serving water system, then use that utility’s own inventory or signup page. ([dep.nj.gov](https://dep.nj.gov/lead/map/?utm_source=openai))
- If your line is listed as unknown, submit the utility’s self-identification survey or request an inspection so your property can be prioritized correctly. ([newarkleadserviceline.com](https://www.newarkleadserviceline.com/replacement))
- If your utility offers free replacement, respond quickly to right-of-entry or consent forms; some programs require homeowner authorization before scheduling. ([newarkleadserviceline.com](https://www.newarkleadserviceline.com/replacement))
