374Water and Arcadis Team Receives U.S. Department of Defense Success Memo Opening Pathway for AirSCWO(TM) Technology for PFAS Destruction at Commercial Scale
Rhea-AI Summary
374Water (NASDAQ: SCWO) announced that the U.S. Department of Defense Defense Innovation Unit issued a Success Memo to partner Arcadis, validating the economic and technical viability of 374Water’s AirSCWO PFAS destruction technology and formally closing the DIU/ESTCP prototype phase.
The Success Memo, under the federal Other Transaction Authority framework, enables federal agencies to move directly to follow-on production awards and procure AirSCWO as a commercial product. This aligns with 374Water’s Orlando Waste Destruction Services hub, which serves PFAS, biosolids, industrial sludges and other difficult waste streams and targets $3–$5 million in annual recurring revenue at initial scale following expansion to 88,000 gallons of onsite storage and upgraded AirSCWO throughput capacity.

The DoD Success Memo enables government contracting officers to rapidly procure goods and services across all Federal agencies, accelerating deployment of 374Water's AirSCWO technology into the large and growing Federal marketplace.
MORRISVILLE, NC / ACCESS Newswire / August 13, 2026 / 374Water Inc. (NASDAQ:SCWO) ("374Water" or the "Company"), a cleantech and environmental services company deploying supercritical water oxidation ("SCWO") technology for the permanent destruction of PFAS and hazardous organic waste streams, today announced that U.S. Department of Defense ("DoD") Defense Innovation Unit ("DIU") issued a Success Memo to 374Water's demonstration partner, Arcadis, validating the performance of 374Water's AirSCWO™ destruction technology.
The Success Memo formally validates the economic and technical viability of a regional AirSCWO hub following a robust demonstration and evaluation program under the DoD's Environmental Security Technology Certification Program ("ESTCP"). It also designates successful completion of the Prototype Project (HQ0034-20-9-DIU) under 10 U.S.C. §4022 and establishes the conditions under which federal agencies may proceed directly to follow-on production awards.
This milestone connects federal validation with 374Water's commercial Waste Destruction Services ("WDS") platform in Orlando, Florida, where the Company is building critical destruction infrastructure to serve PFAS, biosolids, industrial waste, and other difficult-to-treat waste streams.
"Over the past several months, we have been focused on building the AirSCWO operating platform, and the vision is taking shape," said Danny Bogar, CEO of 374Water.
"We have established our long-term Waste Destruction Services hub in Orlando, creating a scalable platform for recurring revenues. We continue to earn market validation under the highest scrutiny, most recently through the Orange County Sanitation District acceptance test and now this Success Memo from the DoD's Defense Innovation Unit. Together, these milestones increase our commercial momentum as we bring this critical infrastructure to the markets that need it most."
The Federal Market
The Department of Defense has identified 574 military installations where PFAS contamination requires remediation action. To date, one facility, the New Hampshire Pease Air National Guard base, has been remediated at a reported cost of more than
While destruction of AFFF is underway, with approximately one billion dollars spent to date, large legacy stockpiles of AFFF and its residual contaminants need to be destroyed and replaced with a new, non-fluorine-based firefighting foam. In addition to the DoD, the Departments of Energy and Transportation are directly involved in PFAS remediation projects around the country.
"The DIU Success Memo confirms, in writing, that AirSCWO performs as advertised, and that federal agencies can procure it as a commercial product," said Howard Teicher, VP, Government at 374Water. "The OTA is expected to significantly accelerate the Federal government's PFAS remediation efforts, and with our partnership with Arcadis and the commercial infrastructure to perform 374Water is leading the way to destroy forever chemicals forever."
What Does a "Success Memo" Mean?
The DIU/ESTCP program is one of the most comprehensive independent evaluations of PFAS destruction technologies to date, validating AirSCWO's ability to treat a broad range of real-world waste streams generated by municipalities, industry, and government agencies.
Under the federal Other Transaction Authority ("OTA") framework, a DIU Success Memo formally closes the prototype phase and authorizes production awards. For 374Water, the practical significance is procurement by federal agencies seeking permanent PFAS destruction at scale. These agencies are authorized to move directly toward deployment with a validated, OTA-eligible technology and an established partner team.
"This Success Memo is a milestone for both Arcadis and 374Water," said Dr. Craig Divine, Senior Vice President at Arcadis. "The AirSCWO technology coupled with this Success Memo offers the whole of the US Military, and in fact any Federal entity, streamlined contracting options and the ability to permanently destroy AFFF and other PFAS wastes. Arcadis is a trusted advisor with significant federal contracting experience and after the extensive technology validation completed during this DIU/ESTCP program, we are pleased to collaborate with 374Water."
The Regional Hub Model: Built for This Moment
The DIU/ESTCP prototype project evaluated the hub-and-spoke concept that underpins this strategy: centralized PFAS destruction facilities capable of receiving concentrated waste streams from multiple installations and industrial customers across a geographic region. Orlando is 374Water's first commercial expression of that model.
Commercially, the Orlando WDS platform translates those demonstration results into a service model for customers that need long-term destruction capacity for biosolids, PFAS, industrial sludges, microplastics, pharmaceuticals, and other difficult-to-manage waste streams while creating recurring revenue opportunities for 374Water.
"The Orlando Waste Destruction Service platform shows how we intend to turn validated AirSCWO performance into recurring commercial service capacity," added Bogar. "As customers seek permanent solutions for PFAS, biosolids, and other difficult waste streams, we believe 374Water is uniquely positioned at the intersection of environmental infrastructure, regulatory change, and growing demand for destruction technologies. We are building the foundation for what we believe can become a critical piece of the nation's waste destruction infrastructure."
374Water's Orlando Facility - operating under a license agreement with the City of Orlando - is the Company's advanced Waste Destruction Services hub. The expanded facility has added 88,000 gallons of onsite tank storage, upgrade AirSCWO capacity for significantly higher throughput, and target between
The federal procurement pathway opened by the DIU Success Memo and the OTA accelerates 374Water's ability to replicate this model at additional federal, commercial TSDF, or public-private partnership sites by reducing the need to repeat full demonstration cycles before deployment.
