The Safe Drinking Water Act (SDWA), as amended in 1996, requires that the EPA establish criteria for a program to monitor not more than 30 unregulated contaminants every five years.The EPA published the first Unregulated Contaminant Monitoring Rule (UCMR 1) in the Federal Register on September 17, 1999 (64 FR 50556), the second (UCMR 2) on January 7, 2007 (72 FR 367), and the third (UCMR 3) on May 2, 2012 (77 FR 26072). This action meets the SDWA requirement by establishing the terms for the next cycle of monitoring, and identifying the new unregulated contaminants to be monitored during the UCMR 4 period of 2017-2021.
