PFAS

Lake Mirimichi Fish Advisory

On May 23, 2024, the Department of Public Health notified the Plainville Board of Health of the results of per- and polyfluoroalkyl substances (PFAS) measured in fish sampled from Lake Mirimichi in 2022 by the Massachusetts Department of Environmental Protection (MassDEP) summarized in their December 2023 report. PFAS levels in fish collected from this waterbody were above the DPH Fish Action Level (FAL) of 0.22 parts per billion (ppb) indicating that regular consumption of these fish may pose a potential health concern.   

DPH is recommending that sensitive populations should not eat any fish from Lake Mirimichi. The general population should limit consumption of all fish to 1 meal/year.
