Water: Public Notification Rule

Where You Live

Your Local Water System Information

You can access data on individual water systems on-line through Envirofacts. Information available includes basic inventory data, violations reported, and enforcement actions taken against individual water systems since 1993.

Public notification helps to ensure that consumers will always know if there is a problem with their drinking water.  Water suppliers across the country consistently deliver drinking water that meets EPA and state standards. 

As water suppliers test their water, they may discover that levels of certain contaminants are higher than the standards set by EPA or states.  This might happen due to a change in local water conditions, heavy rainstorms, or change in operational conditions at the system.   Water suppliers may also fail to conduct one or a series of their required water quality testing.  Any time a water supplier fails to meet EPA and state standards for drinking water, the water supplier must inform their customers. 

This notification can be provided to consumers in a number of ways.

  • Mail or direct delivery to bill paying customers.
  • Any other method that may reasonably reach persons served who do not receive a bill such as
    • appropriate broadcast media (such as radio and television for Tier 1 notice),
    • publication in a local newspaper,
    • delivery of multiple copies for distribution by customers who provide water to others(i.e., apartment building owners or large private employers),
    • posting notice in public places or on the internet, and/or
    • delivery to community organizations.
