Environmental Working Group, a Washington-based environmental nonprofit, today published a study and map of “forever chemicals” known as PFAS in freshwater fish samples across the country. Researchers found that fresh-caught fish contained significantly higher levels of PFAS than in commercial seafood (278x). Eating one freshwater fish would be the equivalent of drinking water with elevated PFAS levels for an entire month, the researchers concluded.
The organization published an interactive map in tandem with a scientific paper evaluating hundreds of fish samples across the U.S. The nonprofit noted that the consequences of PFAS in freshwater fish would be disproportionately carried by communities that relied on freshwater fish for sustenance or traditional practice.
The data in the map does not appear to include samples directly from the Adirondack Park, but it does include samples from the Hudson River just south of the Blue Line and from the Winooski River in Burlington, which flows to Lake Champlain.
Those samples, taken in either 2008 or 2014, showed total PFAS in freshwater fish filet samples ranging from 3,500 parts per trillion to 14,000 ppt. Samples from the Great Lakes were even higher, registering total PFAS levels at 30,000 ppt or higher. Levels were higher in samples further down the Hudson River.
Let me know if you know of any good sources on PFAS exposure in the Adirondacks.
