Per- and Polyfluoroalkyl Substances
Per- and Polyfluoroalkyl Substances (PFAS) have been considered “emerging contaminants” in recent years and have become one of today’s most significant environmental issues. PFAS are widely detected in soil, groundwater, and surface water, and associated with multiple industries and activities including industrial production and processes, firefighting foams, commercial and consumer products, landfills, and wastewater treatment plants.
We have the expertise, experience, and resources to mitigate PFAS risks and liabilities through innovation, insight, and advocacy wherever they occur.
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.
We recognize that PFAS follow a familiar pattern of emergence based on years of experience with predecessor contaminants, allowing us to anticipate public response, regulatory developments, remedial technologies, and legal issues. Not relying on a single tool, we help clients manage, mitigate, and remediate PFAS through a multi-faceted approach of practical innovation, insight, advocacy, and technology.
PFAS are a multi-faceted issue requiring a multi-disciplinary approach. Our PFAS team consists of a network of technical professionals and consultants throughout the United States and Canada with expertise in hydrogeology, human health, and ecological risk assessment, water and wastewater treatment, remediation, and modeling. This combination of expertise positions us to mitigate risks and liabilities through an appropriate mix of insight, advocacy, risk assessment, risk communication, mitigation, remediation, and treatment.
We conduct self-funded, internal research and development for improved management and remediation of PFAS, and 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) and 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 a significant U.S. Environmental Protection Agency Science to Achieve Results (STAR) grant awarded to New York State to improve the understanding of PFAS occurrence at landfills and their potential impact to drinking water supplies.
PFAS are known to affect a variety of markets and industries, following a lifecycle that includes industrial production, industrial use, use in firefighting foams at fire training and aviation facilities, disposal in landfills, and treatment of affected water supplies among others. While many consultants have limited experience with a particular industry or type of PFAS, Parsons has demonstrated experience across this range of industries, uses, and receptors, including:
- Industrial coating
- Aviation facilities
- Metal plating facilities
- Water supply treatment
- Petroleum facilities
Our experts and practitioners are industry thought leaders who oversee and participate in multiple working groups and expert panels, putting us at the forefront of PFAS issues and solutions. Our leadership participation includes:
- 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
