- Parsons’ patented Thermal Conduction Heating (TCH) technology quickly removes PFAS to below laboratory reporting limits from impacted soil, offering a fast and effective on-site solution.
- A Success Memo is similar to a sole source contract in that it enables DOW buyers to pursue follow-on production contracts without additional competitive procedures.
- The Success Memo positions Parsons to support DOW-led PFAS cleanup efforts with a proven remediation solution.
CHANTILLY, Va. (October 21, 2026) – Parsons Corporation (NYSE: PSN) announced today that it successfully completed a prototype project with the Environmental Security Technology Certification Program (ESTCP) and the Defense Innovation Unit (DIU) for the remediation of per- and polyfluoroalkyl substances (PFAS) impacted soil. Department of War (DoW) agencies can now quickly leverage Parsons’ patented thermal conduction heating (TCH) technology pursuant to 10 U.S.C. § 4022, accelerating PFAS cleanup projects.
PFAS are persistent chemicals that can migrate through soil and groundwater, creating concerns for surrounding ecosystems and nearby communities. As public awareness and regulatory attention continue to grow, fast and effective cleanup is increasingly important to reduce long-term risk, protecting community health, and restoring confidence in impacted sites.
“PFAS impacts remain a significant environmental challenge, and our government clients trust Parsons to deliver effective remedial solutions with speed and confidence,” said Mark Fialkowski, president, Infrastructure North America for Parsons. “The successful completion of this project reinforces that trust and strengthens our ability to help agencies address PFAS impacts with a proven technology, quickly and cost effectively and reflects our ability to bring our global portfolio of integrated solutions to customers we already work closely with in other important mission areas.”
Parsons demonstrated its TCH technology under a competitive ESTCP prototype project, where the company removed PFAS to below laboratory reporting limits from impacted soil on-site. This project provided a more sustainable solution by eliminating the transportation and offsite disposal of large amounts of contaminated material to landfills or disposal facilities, saving time and reducing environmental impacts, liability, and risk to people and the environment.
