Board approves Well siting study after consultants flag PFAS in Well 8; plan will evaluate replacement source options
Summary
Following PFAS detections in Well 8, the Village Board approved a well-siting study proposal (not to exceed $54,700) to locate a larger-capacity replacement well and assess legal and contamination risks for potential sites.
The Village Board of East Troy approved a well-siting study on Monday to identify potential locations for a new, larger-capacity municipal well after PFAS contaminants were detected in Well 8 in December 2023.
Staff and Strand consultant Ryan Wood explained that Well 8, one of the village’s shallower wells, had PFAS detects and was taken offline. The study—authorized by motion and second and approved by the board—not to exceed $54,700 will evaluate candidate well sites, water-main extension needs, potential sources of contamination, and the legal risks associated with siting new wells.
Jason (staff member) told the board Well 8’s detect levels prompted the village to remove it from service; Well 8 produces about 300 gallons per minute and uses a generator that staff described as unreliable. Ryan Wood (Strand) told trustees the siting study will use prior master-planning work to determine the anticipated capacity needed to replace Wells 6 and 8 and to evaluate potential lots the village could acquire or service.
Trustees asked whether treatment of Well 8 for PFAS could be feasible. Ryan Wood responded that, based on current costs, in-place PFAS treatment for Well 8 would not be financially viable and that the likely direction is to abandon Well 8 and identify a replacement; Well 6 will be used as practicable until a replacement is in service.
A trustee asked about legal risks following a prior situation with Well 7 and a lake-district lawsuit; staff said the siting study would include an evaluation of legal risks and DNR procedural requirements to avoid repeating past problems. The board approved the contract for the siting study and directed staff to proceed.
