CHANTILLY, Va., July 06, 2026 (GLOBE NEWSWIRE) — Parsons Corporation (NYSE: PSN) today announced the expansion of its comprehensive solutions to mitigate the impacts of per- and polyfluoroalkyl substances (PFAS) on the environment. A leading provider of PFAS services across the United States and Canada, Parsons leverages 20 years of experience to strengthen its preeminent market position and advance its commitment to delivering sustainable PFAS solutions.
“Our investment in advanced PFAS technologies has positioned Parsons at the forefront of this critical environmental challenge. Our integrated suite of solutions addresses PFAS concerns and helps our clients meet today’s regulatory demands, while shaping the future of sustainable remediation,” said Carey Smith, chair, president, and chief executive officer for Parsons. “PFAS destruction technologies and holistic PFAS solutions are a strong example of how we translate innovation into long-term value for our clients and communities.”
Parsons applies an integrated, science-driven approach to PFAS challenges, combining advanced treatment technologies with practical implementation strategies tailored to each project. With a dedicated team of technologists, Parsons has delivered PFAS solutions for two decades, identifying future emerging contaminants and developing solutions to eliminate these pollutants – including PFAS – ahead of our clients’ needs. Parsons’ industry leading internal research and development program drives continual innovation of new remedial technologies and solutions. The company’s solutions are designed to reduce risk, meet evolving regulatory requirements, and deliver sustainable long-term outcomes at a competitive cost.
At the core of Parsons’ PFAS portfolio are four primary solutions: Hot In Situ Chemical Oxidation (Hot ISCO), Catalyzed Ultraviolet (UV) PFAS Destruction (Catalyzed UV), Thermal Desorption, and Aqueous Film-Forming Foam (AFFF) Cleanout services. Together, these four pillars provide a comprehensive PFAS management offering that span environmental investigation, removal from the consumer product stream, active in-situ and ex-situ destructive PFAS remediation and long-term stewardship.
This broad range of proven yet continuously advancing technologies provides Parsons’ clients with unique solutions and positions the company as a trusted partner for complex PFAS challenges across water, soil, and infrastructure. As new PFAS standards emerge and clients seek more sustainable, cost-effective solutions, Parsons can scale, refine, and integrate these technologies to expand service offerings, enter new markets, and drive continued innovation in PFAS management.
- A patented technology in the U.S. and Canada, Parsons’ Hot ISCO is the first in-situ destructive technology on the market for PFAS.
- The technology targets PFAS-impacted source zones by coupling elevated temperatures with in-situ catalyzed chemical oxidation to destroy PFAS in-situ.
- Hot ISCO is also easily and efficiently applied ex-situ to destroy PFAS mass in contaminated water, wastewater, and manufacturing plant waste streams.
- This technology addresses difficult-to-reach source areas, without disrupting surface infrastructure, safely, rapidly, and cost effectively, resulting in shorter cleanup timeframes.
Thermal Desorption of PFAS
- A patented, turn-key solution for on-site applications, thermal desorption uses heat to remove PFAS from soil and other solids, and then destroys PFAS and other contaminants in the off-gas stream.
- This technology has been fully demonstrated on soil piles up to 2,000 cubic yards in size and in cold weather environments, including a project in the winter in Anchorage, Alaska for the United States Department of War (DOW) and the Defense Innovation Unit (DIU).
- This proven soil and debris treatment technology is rapidly implementable and scalable to remote and non-remote sites.
- A patent-pending technology that destroys PFAS in water, wastewater and complex liquid waste streams using UV-based catalytic reactions to break down these persistent compounds.
- Achieves greater than 99 percent of PFAS destruction under real-world conditions at a small fraction of the cost of competing high-energy and capital cost-intensive technologies.
- Fully demonstrated at laboratory and field scale for wastewater matrices such as AFFF cleanout solutions, landfill leachate, industrial wastewater, and contaminated groundwater, as well as in regeneration brines.
AFFF Cleanout of Fire Suppression Systems
- Parsons’ AFFF cleanout service is an advanced capability that combines the company’s proprietary equipment and methods with PerfluorAd®, a product invented by Cornelsen for which Parsons is the exclusive North American Provider.
- This method achieves a much higher degree of AFFF system cleanout (99+ percent PFAS removal) at a competitive cost, protecting firefighters and reducing client’s long-term liability.
- AFFF cleanout service can be combined with Hot ISCO or UV PFAS Destruction for a turnkey, zero waste solution for firefighting clients that mitigates the risk and liability associated with PFAS firefighting foam.
Across installations and complex PFAS-impacted sites, Parsons’ PFAS solutions are being recognized through a growing portfolio of contract wins highlighting both our technical leadership and ability to deliver results at scale.
Thermal Desorption of PFAS in Soil: Joint Base Elmendorf-Richardson (JBER)
- Parsons completed a large thermal desorption of PFAS in soil remediation project at JBER in Anchorage, Alaska. The DOW and DIU funded and administered the 2,000 cubic yard soil stockpile project, respectively. The field study included detailed monitoring, sampling and analysis to track the status of PFAS and remedial results.
UV PFAS Destruction Field Demonstration:
- Parsons has demonstrated proof-of-concept for the feasibility of an aqueous-electron-based complete defluorination and destruction of PFAS in aqueous phase media simulating wastewater, groundwater, and regeneration brines. Multiple projects are in development throughout North America including the support of VEI Contracting (VEI) who was awarded a pilot project for using this technology on a Canadian federal site with full study completion scheduled for Summer 2027.
AFFF Mobile System Cleanout:
- Tucson International Airport – Parsons is managing the cleanout of the airport’s fire response trucks and of the design and execution of the airport wide PFAS remedial investigation.
- Denver International Airport – In 2025, Parsons managed and completed the cleanout of 20 fire response vehicles and trucks, with an average of 95 percent PFAS removal across the entire fleet.
- Oakland San Francisco Bay Airport – Parsons oversaw and led the cleanout of six fire response vehicles and one fixed storage tank in 2025. The results achieved a removal of 99 percent PFAS removal from all trucks and the tank.
- Parsons presented the AFFF cleanout capabilities with the Environment Canada and Climate Change AFFF working group to help Canada industry transition to non-PFAS containing foams.
Together, these capabilities reinforce Parsons’ role as a trusted PFAS partner, helping clients navigate evolving regulations, reduce long-term risk, and protect communities and critical infrastructure for the future.
