374Water Inc (NASDAQ: SCWO) has announced peer-reviewed preliminary data showing 99.9999% destruction efficiency of PFAS in aqueous film-forming foam (AFFF) using their AirSCWO technology. The findings were published in the National Ground Water Association Journals by Arcadis researchers.
AFFF, widely used in firefighting for flammable liquid and gas fires, contains PFAS which pose significant environmental and health risks. With the U.S. Department of Defense and European Union mandating transition to fluorine-free firefighting foams in 2024, 374Water's AirSCWO system is positioned as a potential large-scale solution for AFFF disposal.
The Arcadis study identifies four waste types at AFFF remediation sites: concentrate, rinsate solutions, cleaning agents, and contaminated solid wastes. Unlike traditional disposal methods such as landfilling that carry long-term liability, the AirSCWO technology offers permanent destruction of these hazardous materials, positioning the company to support growing demand across federal, municipal, and industrial markets.
374Water Inc (NASDAQ: SCWO) has announced an updated timeline for deploying its AirSCWO 6 System at Orange County Sanitation District Plant No. 1. The project includes system manufacturing completion in March 2025, Factory Acceptance Test in May 2025, and system delivery to Fountain Valley, California in May 2025.
OC San, which processes over 180 million gallons of wastewater daily serving 2.6 million people, currently transports 525 wet tons of biosolids daily to California and Arizona. The deployment is expected to generate approximately $1.3 Million in revenue from Q2 to Q4 2025.
374Water engineers will manage operations for the first six months, conducting a Controlled Performance Study and training OC San staff. After one year, OC San will evaluate upgrading to the larger AirSCWO 30 system and potentially installing up to five AirSCWO 200 systems at its Huntington Beach facility.
374Water Inc. (NASDAQ: SCWO) has announced its participation in a Department of Defense (DoD) project to demonstrate commercial-scale solutions for destroying PFAS contaminated wastes. The company will deploy its AirSCWO technology at Clean Earth's Detroit facility, in partnership with Arcadis and Clean Earth.
The project is a collaboration between the DoD Environmental Security Technology Certification Program (ESTCP) and the Defense Innovation Unit (DIU). The initiative aims to provide treatment options for DoD installations affected by PFAS, particularly following the U.S. National Defense Authorization Act mandate to transition to fluorine-free firefighting foams by October 2024.
374Water's AirSCWO technology has demonstrated >99.99% destruction of PFAS compounds within seconds in commercial-scale applications, including Aqueous Film-Forming Foam, Granular Activated Carbon, and other waste streams. The system converts hazardous waste into clean water, mineral by-products, and recoverable heat energy.
374Water Inc (NASDAQ:SCWO) has published a white paper demonstrating their AirSCWO system's effectiveness in destroying PFAS-laden ion exchange resin. The system consistently achieved >99.9% total PFAS elimination in both bench and commercial scale field trials.
The paper addresses the critical issue of disposing spent anion IX (AIX) resin containing PFAS 'forever chemicals,' which are synthetic substances linked to various health issues including thyroid disease, fertility problems, and cancer. Traditional disposal methods like landfilling or incineration can lead to environmental contamination.
The company's technology targets the growing spent media market, valued at $1.3 billion as of 2024. The AirSCWO system offers a solution that aligns with recent EPA regulatory requirements for drinking water and CERCLA, focusing on eliminating PFAS and other contaminants while producing safe dischargeable water streams, mineral effluent, vent gas, and recoverable heat energy.
