HKA experts underscore the critical role of experts in PFAS Litigation
18th January 2026
As Featured in Corporate Disputes Q&A
PFAS litigation is one of the most pressing challenges in environmental and commercial disputes today. HKA is pleased to announce that two of our leading environmental experts, Alex Lee, Partner and Geraint Williams, Associate Technical Director, have been featured in the January edition of Corporate Disputes magazine mini-roundtable exploring the escalating complexities of PFAS litigation and the indispensable role of expert witnesses in high-stakes disputes.
“Expert testimony is often the linchpin in PFAS disputes, where outcomes hinge on intricate scientific and technical evidence. Legal strategies succeed when supported by precise technical insight and clear communication to audiences without scientific backgrounds.”
Geraint Williams, Associate Technical Director, HKA
PFAS (per- and polyfluoroalkyl substances) litigation is rapidly expanding globally, driven by heightened regulatory scrutiny, evolving toxicological science and mounting claims for environmental and health impacts. The Q&A examines why expert witnesses are indispensable in these cases and how science and law intersect in this complex litigation.
“Experts play a vital role in translating complex PFAS science into defensible arguments that stand up in court. PFAS litigation has grown in scale and complexity, spanning environmental cases, consumer product claims, and even commercial transactions. Courts rely on experts to interpret toxicology, exposure modelling, and contamination patterns to ensure arguments are scientifically robust and legally defensible.”
Alex Lee, Partner, HKA
The Q&A discussion also underscores:
- Challenges in proving causation and tracing contamination sources
- Evolving regulations and toxicology and their impact on litigation strategies
- Global litigation trends, including multibillion-dollar settlements and emerging cases in the UK, EU, and beyond
