The Safe Drinking Water Act (SDWA), as amended in 1996, requires that EPA establish a program to monitor specified unregulated contaminants every five years from Public Water Systems (PWS). The monitoring effort historically consisted of data collection from large PWS systems (serving > 10,000 people) and representative small PWS serving less than or equal to 10,000 people. EPA published the first Unregulated Contaminant Monitoring Rule (UCMR) in 1999. More than two decades later, EPA has now finalized its 5th cycle of unregulated contaminant monitoring under the now final UCMR 5. EPA published its final Rulemaking on December 27, 2021 with an effective date of January 26, 2022.
