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.

Utility sampling round of residential drinking water did not equal or exceed EPA action levels for lead (state-level)

This measure is a regulatory requirement.

At the state level, this metric shows the percentage of drinking water systems with 90th percentile lead levels in any sampling round in the most recent calendar year in accordance with the federal Lead and Copper Rule (LCR). The LCR requires that utilities sample drinking water in residences of high risk for lead (or other customers if insufficient high-risk households are available). The utility is required to take action if the 90th percentile result (e.g., for 100 samples, the 10th highest result) exceeds 15 parts per billion (ppb) of lead. Note that a water system can have a small number of samples above the action level, but not incur an action level exceedance if the 90th percentile level is below 15 ppb. All federal drinking water regulations are automatically adopted into New Jersey regulations by reference.

The percentage was calculated out of the number of systems with reported lead results, rather than out of the total number of systems in New Jersey. Percentages by system size: 95% of large systems, 97% of medium systems, and 100% of small systems did not exceed the action level in 2019.

Note: Data for this metric is only reporting on lead and not copper. The information for this metric is updated annually using data from NJDEP, so it may not represent current conditions. Utilities may have already resolved or started to resolve issues identified. To learn more, please read the relevant individual system’s Consumer Confidence Report (CCR) (found on the system page) or visit NJDEP Drinking WaterWatch for additional details that this dashboard does not provide.
