WASHINGTON, D.C. – Today, the U.S. Environmental Protection Agency is releasing the first set of data collected under the fifth Unregulated Contaminant Monitoring Rule (UCMR 5). In the latest action to deliver on EPA's PFAS Strategic Roadmap, UCMR 5 will provide new data that will improve EPA's understanding of the frequency that 29 PFAS and lithium are found in the nation's drinking water systems, and at what levels. The monitoring data on PFAS and lithium will help the Agency make determinations about future actions to protect public health under the Safe Drinking Water Act. This action advances the Biden-Harris Administration's commitment to combat PFAS pollution and safeguard drinking water for all people.'
"PFAS are an urgent public health issue facing people and communities across the nation. The latest science is clear: exposure to certain PFAS, also known as forever chemicals, over long periods of time is linked to significant health risks," said Assistant Administrator for Water Radhika Fox. "That's why the Biden-Harris Administration is leading a whole-of-government approach to address these harmful chemicals. As part of this commitment, EPA is conducting the most comprehensive monitoring effort for PFAS ever, at every large and midsize public water system in America, and at hundreds small water systems."
