Village schedules public hearing on water-supply plan after staff flags PFAS monitoring and treatment planning

Tom (village utilities staff) presented the draft Water Supply Service Area Plan required by state regulators and said the village is soliciting public comment for 30 days and will hold a public hearing on June 9, 2025.

Tom said the plan looks at the village’s water supply, storage and projected demands over the next 20 years and that one near-term issue is PFAS. He told the board that Well No. 6 has a measured PFAS concentration the staff recorded as 4.1 (units and regulatory threshold to be set by the state) and that the village is preparing budgetary estimates for treatment should the state adopt a maximum contaminant level (MCL) that would require action. He said the Environmental Protection Agency has published guidance but the state has not yet set an enforceable PFAS MCL; the village would have until 2029 to comply if the state adopts one.

Tom said the village recently reached the population threshold (10,000) that triggers additional sampling and reporting obligations and that staff have been collecting representative samples across the distribution system. He recommended public review and the June 9 public hearing so residents and stakeholders can comment on the plan before the village transmits a finalized plan to the Department of Natural Resources.

Trustees voted to set the public hearing for June 9, 2025. The motion passed after a motion and second; the transcript records the vote as carried without a member-by-member roll call.

Why it matters: PFAS monitoring and potential treatment have capital and operating budget implications. The DNR-required plan sets the village’s service-area projections and influences infrastructure priorities and CIP budgets.

What to watch: results of additional sampling, staff’s cost estimate for PFAS treatment, and the June 9 public hearing.
