What is UCMR4?

January 2018 marks the start of the USEPA’s Unregulated Contaminant Monitoring Rule 4 (UCMR4) sampling and analysis period.  All public water supplies (PWS) serving more than 10,000 people are required to monitor for a 12-month period between January 2018 and December 2020.

Population will be based on size of system as of December 31, 2015.  EPA selects the nationally representative sample of small systems serving 10,000 or fewer as well.

Monitoring Requirements

The UCMR4 final rule requires PWSs to analyze drinking water for 29 unregulated contaminants and one group of regulated contaminants (HAAs).  The monitoring data may influence future regulatory actions to protect public health.

  • TOC & Bromide – SR (Source Water Intake Locations)
