Number of drinking water service lines reported to be of unknown composition (system-level)

This measure is a regulatory requirement.

At an individual system level, this metric shows the number of service lines within the drinking water system's service area that are of unknown composition in the utility-owned and/or property-owned sections, based on drinking water system reports submitted to NJDEP. Generally, service lines refer to the pipes that deliver water from the water main to an individual building. Over time, a utility should show a reduction in service lines (LSLs) of unknown composition, as more service lines are verified to be either lead service lines or not lead service lines. When a LSL is verified, it becomes part of the metric ”Number of drinking water service lines reported to be made of lead”.

Note: Per the LSL replacement law signed in July 2021, all drinking water systems are required to report both lead service lines and lines of unknown composition. Identifying unknowns is a critical first step for utilities to ultimately have an accurate assessment of their entire inventory. This metric is updated annually using data reported to NJDEP and does not reflect real-time status for your water system. Visit your drinking water utility website via the JWC system finder page to see the current status on replacing lead service lines.
