Per - and Polyfluoroalkyl Substances (PFAS)
Integral is at the forefront of technical and regulatory PFAS developments. Our experts guide you through the evolving PFAS regulatory landscape and evaluate associated risks. We conduct environmental sampling, perform site investigations, assess fate and transport, develop conceptual site models, perform advanced forensics, evaluate toxicity and associated risk, engineer remediation solutions, assist with litigation, and help you develop clear and concise communication materials that meet your technical, regulatory, legal, and stakeholder needs.

Litigation Support & Expert Testimony
We assist our clients in PFAS litigation by providing consulting and testifying experts who have outstanding scientific experience and academic and professional credentials. Integral’s litigation support team assists our clients by identifying and gathering available facts and information to prepare compelling arguments and damage assessments to support arbitration, reach settlement, and develop trial testimony, when needed. We skillfully communicate complex technical information in understandable narratives in expert reports, deposition, affidavits, and trial testimony.
Forensics
Integral’s deep understanding of the evolution of PFAS manufacturing, commercial formulations, chemistry, and use over time provides a broad foundation for developing unique insights into our client’s issues and concerns. Forensic investigations vary in complexity, but always benefit from our multidisciplinary perspective that considers the original release mechanisms, chemical alterations in the environment, and fate and transport through environmental media and that often utilizes advanced statistical techniques. Our work provides our clients with an understanding of the probable sources in play at a site, the contributions of PFAS from each source, and any limitations in the data used to support these conclusions.
Remediation & Water Treatment
Our clients rely on our expertise in remediating contaminated soil, sediment, and surface- and groundwater. Applying our extensive remediation experience, we complete thorough feasibility studies, engineering evaluations, pre-design studies, and cost analyses to support a cost-effective overall remedial solution. These efforts build on and inform conceptual site models that guide application of effective remediation technologies and overall liability reduction. We then complete remedial design and implementation serving as the engineer-of-record, owner’s representative, and/or construction manager, as needed.
Site Investigation for PFAS
Reaching the highest value conclusions requires asking the right questions. We foster interdisciplinary and collaborative processes that appropriately identify key issues and data gaps that need resolution. Our team then designs and delivers efficient, science-based, multimedia environmental investigations that delineate the extent of PFAS in the environment and support risk evaluations and cost‑effective remediation strategies. We provide solutions that are protective, sustainable, and consistent with regulatory, client, and other stakeholder needs.
Health Sciences
Integral helps clients navigate the complex and rapidly evolving landscape of PFAS regulation and risk. Our team tracks federal and state criteria, interpreting what they mean for different industries and sites. We apply PFAS-specific toxicology and exposure science to develop accurate, defensible risk assessments tailored to each client’s goals. From biomonitoring study design to regulatory program development, our nationally recognized experts provide clarity and confidence in managing emerging contaminant risks.
