Mayor Fasbender called the workshop to order at 5:30 p.m., welcoming Council members and
Public Works Director Ryan Stempski to provide an update on PFAS. Stempski provided an
outline of the topics to be presented: status of the environmental review, the goals, an evaluation
of the options to address the issue, the costs associated with the preferred option, funding
sources, and next steps.
Stempski reminded Council that the current measurement standards that the six City wells adhere
to the current index and levels have been steady. However, the new standards are expected to be
released by the end of this year.
Stempski reported on the status of the Environmental Review by MPCA. Phase 1 is complete
and Phase 2 has started. They meet monthly to discuss the activities. The deliverables that we are
waiting on include modeling results, MGS complexities, and investigations of other potential
sites.
The study goals are to evaluation options to mitigate PFAS from drinking water, update the
water model to determine feasibility and cost estimates, and provide recommendations on the
most cost-effective solution.
The options include blending existing wells to dilute below the limits, construct deeper wells,
purchase treated water from St. Paul Regional Water Services, or implement treatment on
existing wells. Treatment is the only feasible option. Several treatment options were reviewed to
treat PFAS and continue to treat nitrates. The most common treatment technologies include
Granular Activated Carbon (GAC) and Ion Exchange (IX). The next recommendation is that the
system be decentralized (three vs one plant). This is preferred because the construction can be
phased, it provides operational flexibility and resiliency, wells can continue to pump into
existing pressure zones, and existing distribution mains are adequately sized.
