An investigation into Vancouver, Washington, municipal water reveals concerning levels of PFAS chemicals, raising health and safety questions for the community. In short:Vancouver's municipal water contains PFAS levels above state limits, potentially affecting half the city's water supply. Communications from officials downplay the risks, often omitting key information, which could lead to a false sense of safety among residents. Building facilities to reduce PFAS below state limits could take years and millions of dollars, leaving the community at risk in the interim. Some PFAS bioaccumulate—build up—which means even low exposures are cause for concern over time as our bodies accumulate more and more of them.
