PFAS Solutions

Per- And Polyfluoroalkyl Substances

Per- and polyfluoroalkyl substances (PFAS) have been considered emerging contaminants in recent years. They’ve become one of today’s most significant environmental issues. PFAS are widely detected in soil, groundwater, and surface water, and are associated with multiple industries and activities, including industrial production and processes, firefighting foams, commercial and consumer products, landfills, and wastewater treatment plants. Learn more about our PFAS solutions below.

We have the expertise, experience, and resources to mitigate PFAS risks and liabilities through innovation, insight, and advocacy.

The legal and regulatory landscape for PFAS is in flux and continues to evolve. However, significant progress has been made in the technical understanding of PFAS, including the science and technology necessary to manage and mitigate risks related to PFAS in the environment.

Our Approach

We recognize that PFAS follow a familiar pattern of emergence based on years of experience with predecessor contaminants. This allows us to anticipate public response, regulatory developments, remedial technologies, and legal issues. Without relying on a single tool, we help clients manage, mitigate, and remediate PFAS. We achieve this through a multifaceted approach that utilizes practical innovation, insight, advocacy, and technology.

PFAS-containing firefighting foams
We’ve investigated multiple installations throughout the United States where firefighting foams that contain PFAS were used.


PFAS are a multifaceted issue requiring a multidisciplinary approach. Our PFAS team consists of a network of technical professionals and consultants throughout the United States and Canada who are experts in hydrogeology, human health, ecological risk assessment, water and wastewater treatment, remediation, and modeling. This combination of knowledge positions us to mitigate risks and liabilities through insight, advocacy, risk assessment, risk communication, remediation, and treatment.


PFAS data evaluation technique

We conduct self-funded, internal research and development for the improved management and remediation of PFAS. In addition, we collaborate with world-renowned research organizations on PFAS destruction technologies, testing methods, and analytical tools.
Our treatability laboratory is optimizing proven filtration technologies for a wide range of PFAS, including familiar compounds such as perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA). It also works with replacement products such as hexafluoropropylene oxide dimer acid (HFPO-DA), more commonly known as GenX.

Through our PFAS investigations and data analysis, we’re a key contributor to the Science to Achieve Results (STAR) grant. This US Environmental Protection Agency grant is awarded to New York state and improves the understanding of PFAS occurrence at landfills and their potential impact to drinking-water supplies.

Industry Experience

pfas industries

PFAS are known to affect a variety of markets and industries throughout their life cycle, including industrial production and use, foams at fire-training and aviation facilities, landfill disposal, water-supply treatment, and more. Many consultants have limited experience with a particular industry or type of PFAS. Parsons has demonstrated experience across a range of industries, uses, and receptors, including the following:

  • Manufacturing
  • Industrial coating
  • Firefighting
  • Aviation facilities
  • Metal plating facilities
  • Landfills
  • Water supply treatment
  • Petroleum facilities

in multiple working groups and expert panels. This puts us at the forefront of PFAS issues and solutions. Our leadership participation includes the following:

  • Interstate Technology and Regulatory Council (ITRC) PFAS Team
  • Agency for Toxic Substances and Disease Registry (ATSDR) Historical PFAS Reconstruction Study Expert Panel (former Pease AFB)
  • National Ground Water Association (NGWA) PFAS Writing Group
  • NGWA PFAS Conference Committee
  • Natural Sciences and Engineering Research Council of Canada
Thought Leadership: Mitigating PFAS And Changing The Paradigm

Our environmental experts are working hard to find new ways to help our clients mitigate PFAS contamination. This includes researching new methods to destroy these non-degrading contaminants. Read more about these efforts from Parsons’ PFAS researcher.
