"The Environmental Protection Agency proposed Thursday to include microplastics and pharmaceuticals on a list of contaminants in drinking water for the first time, a step that could lead to new limits on those substances for water utilities.

EPA Administrator Lee Zeldin said they are responding to Americans who have worried about plastics and pharmaceuticals in their drinking water. The gesture also aims to hand a win to Health Secretary Robert F. Kennedy Jr.'s MAHA movement, which for months has pressured Zeldin to further crack down on environmental contaminants.

The EPA’s Contaminant Candidate List identifies contaminants in drinking water not regulated under the Safe Drinking Water Act. The agency is publishing the draft of the sixth version of the list, which opens a 60-day public comment period. It expects to finalize the list by mid-November."
