- Define HR2W systems
Community Water Systems (CWSs) and Non-Community Water Systems (NCWSs) that serve schools and daycares. Those systems were identified to be out of compliance for consistently failing to meet primary drinking water standards. The HR2W list criteria was expanded in March 2021 to better align with statutory definitions of what it means for a water system to “consistently fail” to meet primary drinking water standards.
