EPA’s new strategy calls for PFAS destruction technologies at military facilities, Superfund sites and wastewater plants. 374Water’s AirSCWO has already been validated at 99.999% PFAS destruction and is operational.
MORRISVILLE, NC / ACCESS Newswire / October 29, 2026 / 374Water Inc. (NASDAQ:SCWO) (“374Water” or the “Company”), a leading cleantech and environmental services company deploying supercritical water oxidation (“SCWO”) technology for the permanent destruction of PFAS and other organic waste streams, today published its updated October 2026 Investor Presentation. The presentation arrives days after the U.S. Environmental Protection Agency (“EPA”) launched its first agency-wide PFAS technology strategy, which identifies supercritical water oxidation as a destruction technology to advance through testing and partnerships.
The presentation is available on the Investor Relations section of the Company’s website at www.374water.com.
EPA Calls for Destruction Technologies; AirSCWO Is Already in the Field
On October 26, 2026, EPA Administrator Lee Zeldin launched the PFAS Technology, Evaluation, Coordination, and Harmonization (“PFAS TECH”) Strategy. The strategy aims to accelerate PFAS treatment and destruction technologies through funding, public-private partnerships and demonstrations at Superfund sites, military facilities, wastewater treatment plants and drinking water systems. EPA named supercritical water oxidation among the technologies it intends to advance, and plans to issue funds through its STAR and SBIR programs.
The Company’s updated presentation shows AirSCWO already operating in each of the settings EPA named:
- Military: A U.S. Army Corps of Engineers ERDC technical report (TR-26-19), authored and validated by Arcadis, documented 99.9993% total PFAS destruction in AFFF. The Defense Innovation Unit’s August 2026 Success Memo opens a path to follow-on production awards across federal agencies.
- Wastewater plants: The Company’s first Waste Destruction Services hub sits at the City of Orlando’s Iron Bridge Water Reclamation Facility, and a mobile AirSCWO campaign for the City of St. Cloud, MN processed four feedstocks, including PFAS-laden spent GAC.
- Drinking water: AirSCWO is designed to process spent GAC and ion exchange resin directly, the media utilities are installing to meet EPA’s 4 ppt limits for PFOA and PFOS.
“EPA has now said publicly what we have been demonstrating for years: capturing PFAS is not the end of the problem, and destruction technologies like supercritical water oxidation are critical,” said Danny Bogar, CEO of 374Water. “Our updated presentation shows where AirSCWO already is: validated by the Army Corps of Engineers, cleared for follow-on federal awards, and proven on real waste in Florida and Minnesota, with our Orange County, California system scheduled for deployment in November. We look forward to working with EPA, the Department of Defense and our utility partners as PFAS TECH moves from strategy to deployment.”

Biosolids: a national problem without a solution. U.S. wastewater plants produce about 16,000 dry tons of biosolids a day, and land application is the largest outlet at 46%. Maine and Connecticut have banned land application, and Virginia will restrict it from July 2027 based on PFOS and PFOA levels. Regional coalitions in California, Florida, South Carolina and Michigan are forming to solve it at scale, the market the Company’s next growth horizon targets.
