Lead Pipe Data by Area — New Jersey

Lead pipe replacement law in New Jersey

New Jersey's own Lead Service Line law (P.L. 2021, c.183, signed July 22, 2021) requires every community water system to inventory and fully replace all lead service lines by 2031 — public systems are encouraged to finish within 10 years of the law's effective date, with a maximum allowance of 15 years for full compliance. This is independent of, and generally faster than, the federal Lead and Copper Rule Improvements schedule below.

Separately from any state law, the EPA's federal Lead and Copper Rule Improvements require every water system nationwide to submit a baseline inventory and an approved replacement plan by November 1, 2027, then fully replace all lead and "galvanized requiring replacement" lines under its control on a schedule of 10 years or less from that date, replacing at least 10% of its known lead/GRR lines per year. A narrow exception allows a longer schedule only for the roughly 1% of systems with an unusually dense concentration of lead lines, and partial (non-emergency) replacements are prohibited.
