Water supply: quality and standards; access to safe drinking water; require when a water source tests positive for polyfluoroalkyl substances (PFAS). Amends 1978 PA 368 (MCL 333.1101 - 333.25211) by adding secs. 12722, 12723 & 12724.

This bill requires Michigan's Department of Environment, Great Lakes, and Energy to notify private well owners and nearby residents when tests detect unsafe levels of PFAS chemicals in their water. The legislation mandates that the department provide specific guidance on reducing exposure, along with free certified water filters, to those directly affected and to neighbors within a one-mile radius of the contaminated well. Additionally, the bill establishes a voluntary registry to send email alerts about future testing locations and dates, ensuring the public stays informed about potential water quality issues.
