It's Raining 'Forever Chemicals' Around the Great Lakes It's raining
toxins in the Great Lakes region. A team of American and Canadian scientists found
high levels of PFAS chemicals, known as "
forever chemicals," after studying the rainfall in six different sites across the region.
PFAS are per- and polyfluoroalkyl substances. First used in the U.S. in the 1940s,
the chemicals don't break down and can accumulate as time goes on. The PFAS can continue to be ☠️
toxic to humans years later and have shown up in both snow and rain. Samples of rainwater from the area contained PFAS levels of 100 to 400 parts per trillion (ppt)
— the EPA's safe limit for drinking water is 70 ppt.
