1. Quality of our Water

  2. What’s the story?

    Maintaining good water quality is essential to keeping New Jerseyans healthy. Increasing the percentage of community water systems in compliance with state and federal drinking water requirements is a DOH priority.

  3. By the Numbers

    Currently, 97% of NJ community water systems are in compliance with all current state and federal drinking water requirements for water quality.

  4. Our Strategy

    The U.S. Environmental Protection Agency (USEPA) and the New Jersey Department of Environmental Protection (NJDEP) require mandatory, regular monitoring of treated water delivered to the public. Test results are compared to standards for drinking water quality called Maximum Contaminant Levels (MCLs), the maximum permissible level of a contaminant in public drinking water.

    The New Jersey Environmental Public Health Tracking (EPHT) program, working in close partnership with the NJ Department of Environmental Protection (NJDEP), has summarized data on water quality for over 600 community water systems in New Jersey, as well as on water quality for numerous private wells. 

  5. Did you know?

    Community water systems provide drinking water to more than 85% of the state's population.
