PFAS Solutions
PFAS are persistent chemicals found in soil, groundwater, and surface water across a wide range of industries and applications, from manufacturing and firefighting foams to landfills and wastewater treatment. As regulations and science continue to evolve, we help clients understand, manage, and reduce PFAS risks through proven expertise, innovative technologies, and practical remediation solutions.
Our Approach And PFAS Expertise
PFAS challenges require more than a single solution. Drawing on decades of experience managing complex environmental contaminants, we combine technical expertise, practical innovation, regulatory insight, and proven technologies to address PFAS throughout its lifecycle.
Our multidisciplinary team includes specialists in hydrogeology, human and ecological risk assessment, water and wastewater treatment, remediation, modeling, and risk communication. We help clients:
- Assess PFAS impacts and potential liabilities
- Investigate and characterize contaminated sites
- Evaluate treatment and remediation options
- Navigate evolving regulatory requirements
- Implement effective treatment and remediation strategies
- Communicate risk to stakeholders and communities

Our Transition Approach
AFFF Transition Services
Parsons’ AFFF fire fighting system cleanout and transition service combines proprietary equipment and methods with PerfluorAd®, developed by Cornelsen and exclusively provided by Parsons in North America, to remove more than 99% of PFAS from AFFF systems at a competitive cost. Our cleanout service achieves a more effective cleanout than competing services which protects firefighters, reduces long-term liability, and protects the environment. Our cleanout service can be paired with our PFAS destruction technologies Hot ISCO or Catalyzed UV PFAS Destruction to provide an onsite turnkey, fully PFAS destructive, zero-waste solution for mitigating PFAS-related risks.

Thermal Desorption of PFAS
This patented, turnkey thermal desorption technology uses heat to remove PFAS and other contaminants from soil and solid materials, then destroys them in the off-gas stream. Demonstrated on soil piles of up to 2,000 cubic yards—including in winter conditions in Anchorage, Alaska—the technology offers a proven, rapidly deployable, and scalable solution for both remote and non-remote sites. Parsons was recently awarded with a Success Memo from the Department of War’s Defense Innovation Unit following an extensive field demonstration project in Alaska. This Success Memo documents the technical performance and cost effectiveness of our PFAS remediation technology and allows Federal Government clients to sole source award PFAS remediation projects to Parsons to apply this technology.

Hot ISCO
Parsons’ patented Hot ISCO technology, available in the U.S. and Canada, is the first in-situ destructive solution for PFAS. By combining elevated temperatures with in-situ catalyzed chemical oxidation, it destroys PFAS in difficult-to-reach source zones without disrupting surface infrastructure. Hot ISCO can also be applied ex situ to treat contaminated water, wastewater, and manufacturing waste streams, offering a safe, rapid, cost-effective approach that destroys PFAS in place and shortens cleanup timelines.

Destruction of PFAS Using Catalyzed UV
This patent-pending technology destroys PFAS in water, wastewater, and complex liquid waste streams through UV-based catalytic reactions. It achieves more than 99% PFAS destruction under real-world conditions at a fraction of the cost of energy-intensive alternatives and has been demonstrated at both laboratory and field scale across applications including AFFF cleanout solutions, landfill leachate, industrial wastewater, contaminated groundwater, and sorbent regeneration brines.
