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.

Met drinking water standards that protect against harmful bacteria (state-level)

This measure is a regulatory requirement.

At the state level, this metric shows the percentage of total NJ drinking water systems that met monitoring requirements and/or routinely were below the Maximum Contaminant Level (MCL) for E. coli for the Revised Total Coliform Rule (RTCR) regulatory limits according to NJ primary drinking water standards. The primary drinking water standards, also known as Maximum Contaminant Levels (MCLs) under the federal and State Safe Drinking Water Act, are the minimum considered necessary for maintenance of public health and to ensure safe drinking water for consumers. All federal drinking water regulations are automatically adopted into New Jersey regulations by reference. For the purpose of this measure, exceedances of the MCL for E. coli bacteria and major monitoring violations are counted, whereas reporting violations and minor monitoring violations are not.

Percentages by system size: 100% of large systems, 100% of medium systems, and 96% of small systems met the requirements in 2019.

Note: 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. All water has bacteria. Presence of bacteria does not mean water is unsafe to drink. Only disease-causing bacteria lead to disease. All systems have to do testing throughout the year to ensure they are within regulatory limits and bacteria does not exceed a set limit as per regulation.

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.
