On December 7, 2021, the Illinois Environmental Protection Agency (IEPA) filed a rulemaking proposal to update the Board’s groundwater quality regulations. IEPA seeks to uphold the policy of the Illinois Groundwater Protection Act “to restore, protect, and enhance the groundwaters of the State, as a natural and public resource.” 415 ILCS 55/2(b). Specifically, IEPA states that its proposed rule changes are designed to keep Illinois’ standards “current as scientific data and methods supporting the development of groundwater quality standards have evolved.” Among other amendments, IEPA proposes location-specific Class III groundwater quality standards for six dedicated nature preserves, as well as groundwater quality standards for six Per- and Polyfluoroalkyl Substances or “PFAS.”
