Summary

Mary Cahill told council she found historical fluoride test values above the city’s notification threshold and asked how residents were informed; she said tests in 2011 (3.05) and 2020 (2.63) suggest levels above the notification level of 2 mg/L and sought clearer alerts to households with children.

During public comment Mary Cahill said she researched the municipal water quality report and was concerned about elevated fluoride values in past tests. She said longstanding tests showed a 2011 result of 3.05 and a 2020 result of 2.63 and noted guidance that a level above 2 mg/L should trigger notification for pregnant women or children under 9. "If it's above a 2, we should be notified," Cahill said, and asked whether the city’s billing‑notice approach sufficed as notification.

Cahill said city staff (she referenced Dave Stockdale) provided a screenshot of a bill showing a notice and asked council to consider clearer, more prominent alerts for residents with young children. Councilors acknowledged the concern and staff offered to follow up to clarify testing records and notification practices.
