Today, Governor Evers and Secretary Cole accompanied Senators David Hansen (Green Bay) and Mark Miller (Monona) to announce one of the most comprehensive bills in the nation to address contamination by per- and poly-fluoroalkyl substances (PFAS). This bill (LRB-2297/2), if passed, will protect public health as well as the air, waters and lands of Wisconsin.
What would the legislation do?
- This bill requires the Department of Natural Resources to establish and enforce various standards for per- and poly-fluoroalkyl substances (PFAS).
- The PFAS group of substances includes several thousand chemicals (4,000+); two of the most well-known are perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS).
- The bill requires DNR to establish, by rule, the following:
- acceptable levels and standards,
- monitoring requirements, and
- required response actions for any PFAS.
- Applies to all media:
- in drinking water, groundwater, surface water, air, solid waste, beds of navigable waters, and soil and sediment, if the department determines that the substance may be harmful to human health or the environment.
- These rules must cover, at a minimum, PFOA and PFOS, as well as perfluorohexane sulfonic acid (PFHxS), perfluorononanoic acid (PFNA), perfluorobutane sulfonic acid (PFBS), and perfluoroheptanoic acid (PFHpA).
- In recommending a groundwater enforcement standard for a perfluoroalkyl or polyfluoroalkyl substance, the department of health services may recommend individual standards for each substance, a standard for these substances as a class, or standards for groups of these substances.
