en.Wedoany.com Reported - Parsons Corporation (NYSE: PSN) announced the expansion of its comprehensive solution portfolio to mitigate the environmental impact of per- and polyfluoroalkyl substances (PFAS). As a leading PFAS service provider in the U.S. and Canadian markets, the company is leveraging two decades of industry experience to further solidify its market position and advance sustainable PFAS solutions.
Carey Smith, Chairman, President, and CEO of Parsons, stated that the company's investment in advanced PFAS technologies has positioned it at the forefront of this environmental challenge. The integrated solution suite helps clients meet current regulatory requirements while shaping the future of sustainable remediation. PFAS destruction technologies and holistic PFAS solutions exemplify how innovation translates into long-term value for clients and communities.
Parsons employs an integrated, science-driven approach to address PFAS challenges, combining advanced treatment technologies with implementation strategies tailored to each project. The company's technical team has delivered PFAS solutions for the past two decades and is focused on identifying next-generation emerging contaminants and developing technologies to eliminate them. Its internal research and development programs drive continuous innovation in remediation technologies and solutions, aiming to reduce risks, meet evolving regulatory requirements, and achieve sustainable long-term outcomes at competitive costs.
Parsons' PFAS portfolio is built on four core technologies: Hot In-Situ Chemical Oxidation (Hot ISCO), Catalyzed UV PFAS Destruction, Thermal Desorption, and Aqueous Film-Forming Foam (AFFF) Cleanout Services. These four technologies form a comprehensive PFAS management service system, covering environmental investigations, removal from consumer product streams, active in-situ and ex-situ destructive remediation, and long-term management.
Hot In-Situ Chemical Oxidation (Hot ISCO) is Parsons' patented technology, approved in Canada and the U.S., and is considered the first in-situ destruction technology for PFAS on the market. This technology targets PFAS-impacted source zones for in-situ destruction by combining high temperatures with in-situ catalytic chemical oxidation, and can be efficiently applied to ex-situ treatment of contaminated water, wastewater, and industrial process streams. It safely, quickly, and cost-effectively treats hard-to-reach source zones without disrupting surface infrastructure.
PFAS Thermal Desorption is a patented, turnkey field-applied solution that uses heat to remove PFAS from soil and other solids and destroy them in the exhaust gas. This technology has been validated on soil piles up to 2,000 cubic yards and in cold environments, including projects executed for the United States Department of War (DOW) and the Defense Innovation Unit (DIU) during winter in Anchorage, Alaska.
Catalyzed UV PFAS Destruction is a patent-pending technology that uses UV-based catalytic reactions to break down persistent compounds, destroying PFAS in water, wastewater, and complex waste streams. Under real-world conditions, this technology achieves over 99% PFAS destruction at a fraction of the cost of competing high-energy and capital-intensive technologies. It has been validated at both laboratory and field scales across various wastewater matrices, including AFFF cleanout liquids, landfill leachate, industrial wastewater, contaminated groundwater, and regenerated brine.
Parsons' AFFF Cleanout Service combines the company's proprietary equipment and methods with the PerfluorAd® product, invented by Cornelsen Umwelttechnologie GmbH, for which Parsons is the exclusive North American provider. This method achieves a higher degree of AFFF system cleanout at competitive costs, removing over 99% of PFAS. This service can be combined with Hot ISCO or UV PFAS Destruction to provide a turnkey zero-liquid-discharge solution for fire protection clients.
In practice across various facilities and complex PFAS-impacted sites, Parsons' solutions have gained recognition through a growing portfolio of contract wins. For example, at Joint Base Elmendorf-Richardson (JBER) in Anchorage, Alaska, Parsons completed a large-scale PFAS thermal desorption remediation project for soil. Regarding UV PFAS destruction field demonstrations, Parsons has demonstrated the feasibility of complete aqueous-phase electron-based defluorination and destruction of PFAS in aqueous media. Multiple projects are under development in North America, including supporting VEI Contracting's pilot project at a Canadian federal site, with the full research plan scheduled for completion in summer 2027. In AFFF mobile system cleanouts, Parsons completed fire truck and tank cleanouts in 2025 at Tucson International Airport, Denver International Airport (achieving an average PFAS removal rate of 95%), and Oakland San Francisco Bay Airport (achieving a PFAS removal rate of 99%).
Together, these capabilities reinforce Parsons' role as a trusted PFAS partner, helping clients navigate evolving regulations, reduce long-term risks, and protect communities and critical infrastructure.
