The Water Online Show: How Reactivated Carbon Is Revolutionizing Water Treatment

In this episode of The Water Online Show, host Travis Kennedy delves into one of the water industry’s most pressing challenges: PFAS contamination. Tune in to hear about a promising, often underutilized solution: reactivated granular activated carbon (GAC).

Joining the show is Dr. David Mazyck of Penn State University, who breaks down how reactivated GAC—carbon that’s thermally treated for reuse—offers municipalities a sustainable, cost-effective, and often equally or more effective alternative to virgin carbon. Listeners gain insight into rapid small-scale column tests (RSSCTs), a tool for utilities to quickly evaluate reactivated carbon performance. Dr. Mazyck also emphasizes the significant environmental and economic benefits, including lower carbon footprints and up to 50% cost savings.

The conversation is a must-hear for utilities navigating PFAS regulations and rising material costs. With practical guidance and a call to educate and test, this episode equips municipal leaders with actionable next steps in adopting smarter, greener water treatment practices.
