Comment submitted by American Chemistry Council (ACC)

Summary: The American Chemistry Council (ACC) opposes the inclusion of broad chemical and material groups in the Drinking Water Contaminant Candidate List 6 (CCL 6). They specifically argue for the removal of PFAS as a class, microplastics, pharmaceuticals, and 1,4-Dioxane from the list, advocating instead for a targeted, science-based approach focusing on specific contaminants with established analytical methods and clear health risks.
