On the 17th of August, EPA Publishes Preliminary Nationwide Monitoring Results for 29 PFAS and Lithium. The inaugural data set of 12, set to unfold by 2026, continues EPA efforts in combatting PFAS concerns in drinking water.

The EPA is taking a significant step against PFAS pollution with the release of the first set of data collected under UCMR 5. This rule focuses on monitoring the occurrence of 29 PFAS (per- and poly-fluoroalkyl substances) and lithium in the nation’s drinking water systems. By gathering this new data, the EPA aims to gain a better understanding of the frequency and levels at which these contaminants are found.

The data collected under UCMR 5 is pivotal in driving science-based decisions to protect public health under the Safe Drinking Water Act. The Biden-Harris Administration recognizes the urgency of addressing PFAS contamination, as exposure to certain PFAS over extended periods has been linked to significant health risks. Assistant Administrator for Water, Radhika Fox, emphasizes the comprehensive nature of this monitoring effort, covering both large and midsize public water systems across America.

The EPA’s commitment to tackling PFAS pollution is evident in its multifaceted approach. The agency has proposed standards to limit specific PFAS in drinking water, with UCMR 5 data serving as a valuable resource in this effort. As the PFAS drinking water standard nears finalization, the EPA has introduced Health Advisories for four PFAS compounds featured in UCMR 5. Additionally, the agency is actively expanding investigations into PFAS-contaminated sites and working to hold polluters accountable.

To further strengthen its efforts, the EPA is deploying a substantial $9 billion, allocated through President Biden’s Bipartisan Infrastructure Law. The allocated funds will be directed toward communities possessing drinking water systems affected by PFAS and other newly identified contaminants. This financial support includes contributions through the Drinking Water State Revolving Fund (DWSRF) and the “Emerging Contaminants in Small or Disadvantaged Communities” grant program. Together, these resources will aid communities in implementing solutions to remove PFAS from their drinking water.

The EPA’s release of data under UCMR 5 marks a significant milestone in the agency’s ongoing mission to address PFAS pollution and safeguard the nation’s drinking water. By collecting and analyzing comprehensive data on PFAS and lithium occurrences, the EPA is taking concrete steps to protect public health, advance scientific understanding, and ensure safe and clean drinking water for all.
