Study Reveals Ubiquity of PFAS Contamination in Great Lakes

New research highlights the widespread presence of toxic 'forever chemicals' in the water, air, and precipitation of the Great Lakes Basin, posing significant environmental and health risks.

PFAS, or 'forever chemicals,' are found consistently in precipitation across all Great Lakes, regardless of population density.
The chemicals enter the lakes primarily through atmospheric deposition and are removed at varying rates depending on the lake.
Lake Ontario shows the highest contamination levels, while Lake Superior has the lowest.
The EPA has recently classified two PFAS compounds as hazardous substances, imposing limits on their concentrations in drinking water.
Researchers call for broader regulatory measures to control PFAS sources and mitigate their environmental impact.
