Village Releases Water-Supply Plan; PFAS Testing Could Require Treatment Work by 2029
Summary
Public works staff presented the Village of Hartland’s water-supply service area plan and warned of emerging PFAS regulatory limits; well No. 6 is close to levels cited in EPA guidance and staff will budget for treatment if state adopts an MCL.
Tom (public-works presenter) presented the Village of Hartland’s draft water-supply service area plan and explained next steps, sampling requirements and a potential treatment need if the state adopts a federal maximum contaminant level (MCL) for PFAS.
Tom said the mandated plan looks ahead 20 years and documents supply, storage and sampling for the village water utility. He told trustees the immediate technical concern is PFAS: the Environmental Protection Agency has published recommended levels and the state of Wisconsin may adopt a maximum contaminant level by 2029. Tom said Well No. 6 has a PFAS value near the EPA guidance (he reported a reading of 4.1 and noted the measurement has hovered between about 3.8 and 4.14), and staff are beginning to evaluate treatment options and will seek a budgetary number for the capital-improvement plan (CIP).
Tom also noted that, because the village population has exceeded 10,000, the utility is required to perform more extensive sampling and that the village has already recruited more than the required sample participants to satisfy the Department of Natural Resources’ representative-sampling requirements.
The board scheduled a public hearing on the water-supply service area plan for June 9, 2025; staff asked the public to submit written comments and noted the plan is posted on the village website.
Ending note: Staff will return after the 30-day comment period and public hearing; trustees asked staff to include budget estimates for any PFAS-treatment needs in upcoming CIP proposals.
