Welcome to Jersey WaterCheck’s evaluation center — the Benchmark Hub.

The Benchmark Hub helps utility managers and state leaders dive into the factors that contribute to the need for water infrastructure investment. Here you will find the details, measures, reports, results, and data that we’ve gathered for every water and wastewater system in the state.

Number of drinking water service lines reported to be made of or contain lead (state-level)

At the state level, this metric shows the total number of service lines of NJ's drinking water systems that are comprised of or contain some level of lead in the utility-owned and/or property-owned sections, based on drinking water system reports submitted to NJDEP in 2019. Generally, service lines refer to the pipes that deliver water from the water main to an individual building.

Totals by system size: Large systems have 152,920 lead service lines (LSLs), medium systems have 13,161 LSLs, and small systems have 4,200 LSLs. Percent of systems reporting LSLs by system size: large = 31%, medium = 20%, and small = 11%.

Note: Most drinking water systems are still in the process of completing inventories of service lines and some reported numbers represent estimates; as of late 2020, the status is not yet known for many lines. An increase in the number of known lead service lines (LSLs) reported over time indicates positive progress by the water system in identifying LSLs. A decrease indicates progress in removing LSLs. Community water systems submit this information to NJDEP as part of non-regulatory requirements or as requested by the administrative authority.
