In recent years, the environmental and health risks posed by per- and polyfluoroalkyl substances (PFAS) have drawn widespread attention. Addressing PFAS contamination is no simple task. Conventional water and wastewater treatment methods struggle to remove these chemicals effectively. While advanced technologies like granular activated carbon (GAC) and ion exchange (IX) show promise, they often generate PFAS-laden residuals that require careful disposal or destruction. This raises an urgent question: How do we manage these PFAS-contaminated byproducts responsibly?

A Roadmap for PFAS Solutions

Carollo’s national PFAS lead, Kyle Thompson, addresses this pressing issue in a newly published article in Chemosphere. Titled “State of the Science and Regulatory Acceptability for PFAS Residual Management Options: PFAS Disposal or Destruction Options,” the paper explores innovative strategies for tackling PFAS contamination.

The article outlines emerging technologies for PFAS destruction, such as thermal treatments and other advanced methods. These solutions aim to break PFAS molecules down completely, preventing them from reentering the environment. Thompson and his co-authors also examine regulatory frameworks across the United States and internationally, offering utilities and industries a comprehensive guide to navigating this complex landscape.

PFAS Residual Management

One of the article’s key insights is the need for integrated strategies. Pairing separation technologies like GAC and IX with effective destruction methods helps make certain that PFAS residuals are eliminated rather than transferred to another part of the environment.

As federal and state regulations evolve, utilities and policymakers must adapt quickly. This research provides actionable solutions to help the water industry make informed decisions, safeguarding public health and the environment from the risks posed by PFAS contamination.

A Call to Action for the Water Industry

With federal and state regulations evolving rapidly, this research offers timely and necessary insights to utilities, researchers, and policymakers. By providing actionable strategies, the article equips the water industry to tackle PFAS contamination and manage its residuals responsibly.
