Data centers' PFAS pollution risks amid AI-driven expansion

The EPA announced proposals in 2025 to delay PFAS drinking-water compliance and to fast-track chemical reviews for data-center projects.

• EPA proposals (May–Sept 2025): The EPA proposed pushing back the compliance deadline for PFAS drinking-water standards to 2031 and announced plans to fast-track review of chemicals used in data centers to support the goal of making the U.S. the “AI capital of the world”; President Trump issued an executive order directing multiple federal agencies (EPA, DOI, DOE, DOC) to expedite permitting for data-center materials and infrastructure.
• Background and parallel actions: Congress (117th) designated $1 billion via the Infrastructure Investment and Jobs Act (P.L. 117-58) for the Clean Water State Revolving Fund and other PFAS wastewater programs; private-sector and state actions include 3M exiting PFAS manufacturing by end of 2025, Maine’s phased ban on many PFAS products (effective dates 2026–2040, coolants banned from 2040), and Minnesota’s statutes requiring PFAS reporting standards by 2026 and product-sale restrictions effective 2025 with broader bans by 2032.
