On behalf of the 23 undersigned organizations, we are writing concerning work on per- and polyfluoroalkyl substances (PFAS) under Annex 3 of the Great Lakes Water Quality Agreement. We urge the U.S. and Canadian Governments to work together in developing a joint binational strategy to address these chemicals in the Great Lakes region.
As you know, under Annex 3 of the Great Lakes Water Quality Agreement (GLWQA), the Canadian and U.S. Governments (the Parties) have designated two individual PFAS and their isomers (perfluorooctanoic acid, or PFOA, and perfluorooctane sulfonic acid, or PFOS) and one category (long-chain perfluoroalkyl carboxylic acids, or LC-PFCAs) as chemicals of mutual concern (CMCs).
