Early data from a joint EPA-Canadian monitoring network shows widespread deposition of both legacy and replacement short-chain per- and polyfluoroalkyl substances (PFAS) in precipitation in the Great Lakes, driving new calls from environmentalists for officials to adopt a “whole-of-government” approach to address the issue. The EPA monitoring data, analyzed by researchers at Indiana University, showed that “wet deposition of PFAS has clearly exceeded that” of a range of legacy contaminants in the region, including polychlorinated biphenyls, polycyclic aromatic hydrocarbons, organochlorine...
