This presentation provides an overview of the rapidly evolving PFAS regulatory landscape across the US, Europe, and Asia, with a focus on how differing definitions, reporting requirements, and enforcement timelines affect industrial and semiconductor facilities. It walks through recent and proposed regulations under frameworks such as SDWA, TSCA, CERCLA, and REACH, and discusses what these changes mean in practice for permitting, compliance planning, supply chains, and long-term PFAS management strategies.
