374Water Destroys Over 99.9% of PFAS 'Forever Chemicals' in U.S. Military Destruction Demonstration Project

SCWO
  • 374Water Inc. (NASDAQ: SCWO) announced the public release of U.S. government PFAS destruction test results for its AirSCWO™ technology on April 30, 2026.
  • The testing was conducted as part of an official project led by the Defense Innovation Unit (DIU) & the Environmental Security Technology Certification Program (ESTCP).
  • Third-party results presented by Arcadis confirm AirSCWO achieves greater than 99.9% destruction & removal efficiency (DRE) for concentrated liquid PFAS waste streams.
  • Six distinct waste streams were evaluated, including AFFF foam, spent GAC, & various regenerant still bottoms, with DREs ranging from over 90% for solids to over 99.99% for liquids.
  • Specific results showed effluent concentrations at or below method detection limits for key analytes like PFOS, PFOA, & 6:2 FTS.
  • Hydrogen fluoride stack emissions were non-detectable across all tests, confirming the technology fully mineralizes fluorinated compounds without hazardous air emissions.
  • All liquid-phase analysis followed EPA Method 1633, with supplemental air emissions monitoring conducted via multiple validated federal methods.
  • Results were presented at the Northeast Waste Management Officials Association (NEWMOA) Science of PFAS Conference on April 16, 2026, by Arcadis experts.
  • AirSCWO offers a permanent destruction solution for PFAS, contrasting with conventional methods that only concentrate contaminants & create residual waste problems.
  • The technology targets markets including military bases, municipal water systems, & industrial facilities facing tightening regulatory limits & disposal constraints.
  • 374Water plans to share these findings at upcoming conference appearances to discuss SCWO applications.
