Public Act 103-1077

AN ACT concerning health.

Be it enacted by the People of the State of Illinois, represented in the General Assembly:

Section 1. Short title. This Act may be cited as the Safe Public Drinking Water Act.

Section 5. Definitions. As used in this Act:

"Agency" means the Environmental Protection Agency.

"Board" means the Pollution Control Board.

"MCL" means maximum contaminant level, or the legal threshold limit on the amount of a substance that is allowed in public water systems.

"Perfluoroalkyl substance or polyfluoroalkyl substance" or "PFAS" means a class of fluorinated organic chemicals containing at least one fully fluorinated carbon atom.

Section 10. Purpose. It is the goal of the State of Illinois to protect residents from harmful toxins in drinking water. Accordingly, this Act directs the Agency to conduct statewide sampling of certain community water supplies for the presence of 1,4-Dioxane.

Section 15. Rulemaking; identical in substance. Within one year of the promulgation by the United States Environmental Protection Agency of regulations or amendments establishing MCLs for any PFAS, the Board shall adopt rules that are identical in substance to such federal regulations or amendments, thereby establishing such PFAS MCLs for Illinois' community water supplies.

Section 20. Sampling for 1,4-Dioxane.

(a) The Agency shall, by June 30, 2026, conduct sampling of the Illinois community water supplies previously sampled by the Agency for 1,4-Dioxane from the years 2013 through 2015.

(b) If the results of such sampling detect drinking water levels of 1,4-Dioxane in excess of the United States Environmental Protection Agency Health Reference Level of 35 micrograms per liter, the Agency shall, within 2 years after June 30, 2026, take all actions needed to obtain the expertise necessary to propose rules that will establish a State-only MCL for 1,4-Dioxane.

(c) By no later than June 30, 2029, the Agency shall propose, and, by no later than June 30, 2030, the Board shall adopt, amendments to the Board rules to establish a State-only MCL for 1,4-Dioxane.

(d) The Agency shall, at least annually, convene a stakeholder group to review a subset of chemicals that are likely to pose a substantial health hazard to residents of the State, for the purpose of proposing or revising a State-only MCL for those chemicals.
