Per- and Polyfluoroalkyl Substances (PFAS)


Per- and polyfluoroalkyl substances (PFAS)—also known as “forever chemicals”—are a large family of fluorinated chemicals made up of a chain of linked carbon and fluorine atoms. PFAS have historically been used in multiple applications across a broad range of industries, including aviation, personal care products and cosmetics, biotechnology, construction, electronics, paper, plastics, and pharmaceuticals. For more than two decades, PFAS have been the subject of litigation and the target of regulatory efforts, largely due to their alleged exposure-based health impacts. As in many environmental and “toxic tort” litigations, experienced and enterprising plaintiff firms have been refining and improving their strategies for attacking companies involved with PFAS at all levels, and significantly broadened the scope of potential defendants to target.

MG+M has been a leading defense firm in PFAS-related litigation and counseling since the onset of PFAS litigation. Leveraging more than 18 years of PFAS-specific experience and utilizing the technical backgrounds of our attorneys, including toxicology, epidemiology, public health and environmental science, we thoroughly understand PFAS-related science and medicine and the associated nuances and obstacles companies face with PFAS litigation and regulatory compliance. With firsthand, in-house experience, our attorneys comprehensively navigate the intricate legal, business and scientific challenges PFAS clients face.

MG+M’s PFAS litigation and counseling group advises clients on regulatory compliance, best practices for PFAS-related issues, litigation avoidance and defense strategies. When working with PFAS clients, we collaborate with the country’s best experts and investigators and “partner” with our clients to skillfully and efficiently advise them through legal, regulatory and scientific challenges. MG+M also works with its clients to pinpoint other potential sources of contamination and identify federal and state funding sources for PFAS mitigation and/or remediation. We assess PFAS risks and other emerging issues that can lead to further problems, including excessive costs, future liabilities and potential threats of litigation. If litigation arises, our team collaboratively works with our clients to determine the most favorable approach to resolution. MG+M’s innovative litigation strategies have led to unprecedented success in driving down defense and indemnity costs for its PFAS clients.
