374Water Awarded Aqueous Film-Forming Foam Destruction Contract by the State of North Carolina

Up to 29,000 Gallons Total of AFFF to be Treated by AirSCWO

Major Step Forward in the Removal of Harmful Per- and Polyfluoroalkyl Substances (PFAS) From Firefighting Foam

DURHAM, N.C., March 26, 2025 (GLOBE NEWSWIRE) — 374Water Inc. (NASDAQ: SCWO) (“374Water”) (the “Company”), a global leader in organic waste destruction technology for the municipal, federal, and industrial markets, is pleased to announce that it has been awarded a contract by the State of North Carolina for the destruction of Aqueous Film-Forming Foam (“AFFF”). We recently announced the launch of our Waste Destruction Services (“WDS”), and are thrilled to be providing WDS to the University of North Carolina at Chapel Hill Collaboratory.

North Carolina’s 60,000-gallon AFFF destruction initiative stands as one of the most ambitious state-led per- and polyfluoroalkyl substances (“PFAS”) disposal efforts to date. AFFF has been a critical tool in combating flammable liquid and gas fires, including petroleum, greases, tars, oils, oil-based paints, solvents, and alcohols. 374Water intends to destroy AFFF, secured by the State of North Carolina as part of their State take-back program, per North Carolina’s Responsible Firefighting Foam Management Act (H370) of the 2023-2024 Session. 374Water’s first phase intends to treat 1,000 gallons of AFFF. If selected for the second phase, 374Water could treat up to an additional 28,000 gallons of AFFF. This initiative demonstrates a strong commitment to eliminating PFAS contamination at scale while setting a precedent for future large-scale environmental remediation projects.

“We have a long history of working with a wide range of partners across the State to demonstrate organic waste destruction capabilities, including Duke University, various local utilities and water and wastewater municipalities, as well as industrial and federal partners,” said Sunny Viswanathan, VP of Sales for 374Water. “374Water specializes in the destruction of organic waste streams including concentrated PFAS waste streams, and our AirSCWO system has consistently shown PFAS >99.99% destruction and removal efficiency.”

Chris Gannon, CEO of 374Water, added, “This award marks a significant win for both 374Water and the State of North Carolina, and is a crucial step towards solving the PFAS problem that exists in North Carolina and across the United States. PFAS remains a headline issue for the State, and we are a leader in the field of PFAS destruction.   Our roots are deep in the State of North Carolina, and this award gives us the chance to do the right thing for the citizens and the State.

“Through this partnership, we continue to solidify our role as a trusted leader in sustainable waste destruction, providing innovative solutions to address one of the most pressing environmental challenges of our time. By leveraging our cutting-edge AirSCWO technology, we are helping North Carolina take meaningful action against PFAS contamination and setting a new standard for responsible waste management nationwide. As the project progresses, we look forward to collaborating with stakeholders to expand the reach of our technology and contribute to a cleaner, safer future for communities across the country and beyond,” concluded Gannon.
