PFAS Regulations and Redmond's Drinking Water


OVERVIEW STATEMENT:
recommendation
PFAS (per- and polyfluoroalkyl substances) are a group of human-made chemicals that have the potential to adversely affect human health and the environment. Over the last few years federal and state PFAS regulations have been evolving as more is learned about this emerging contaminant. Redmond has been monitoring the groundwater since 2014 to assess risks to the City's supply wells. Recent sampling efforts, required under federal Unregulated Contaminant Monitoring Rule (UCMR), have detected PFAS in Redmond's supply wells over the state and federal requirements. This informational presentation will provide a high-level overview of PFAS, current and evolving regulations, impacts in Redmond and actions the City will need to take.
