About PFAS / Environmental Contamination Expert Witnesses

PFAS litigation represents one of the fastest-growing areas of environmental law, with thousands of cases pending against manufacturers, military installations, and industrial facilities. In April 2024, EPA finalized the National Primary Drinking Water Regulation establishing maximum contaminant levels for six PFAS compounds, including PFOA and PFOS at 4 parts per trillion, affecting drinking water for approximately 100 million Americans 1. Experts address the fate and transport of PFAS in the environment, health effects documented in ATSDR toxicological profiles, remediation technology and costs, and compliance with these rapidly evolving regulatory standards 2. PFOA and PFOS were also designated as CERCLA hazardous substances, expanding Superfund liability for releases at contaminated sites 3. Given the complexity of PFAS chemistry and the evolving scientific understanding of these persistent chemicals, qualified experts with specific PFAS experience are in high demand.

EPA's April 2024 PFAS National Primary Drinking Water Regulation sets legally enforceable limits for six PFAS compounds and is projected to prevent PFAS exposure for approximately 100 million Americans.

Frequently Asked Questions

What are PFAS and why are they the subject of litigation?

PFAS (per- and polyfluoroalkyl substances) are a class of synthetic chemicals used in firefighting foam, non-stick coatings, and many industrial applications. They are called 'forever chemicals' because they do not break down in the environment. Litigation arises because PFAS contamination has been found in drinking water nationwide and has been linked to cancer and other health effects.

What types of cases require a PFAS expert?

PFAS experts are needed in municipal water contamination lawsuits, military base environmental cleanup disputes, product liability cases against PFAS manufacturers, personal injury claims related to PFAS exposure, and property damage cases where PFAS contamination has affected real estate values.

How much does a PFAS expert witness cost?

In general, environmental expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic experience, certifications and licensure, regulatory expertise, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
