The U.S. Environmental Protection Agency (EPA) has announced a landmark, coordinated action to address microplastics contamination, one of the most urgent and growing public health challenges facing Americans. This action is part of a broader federal effort aligned with the "Make America Healthy Again" (MAHA) agenda and represents one of the most comprehensive steps taken to date to evaluate new environmental health risks. For the first time, the EPA has included microplastics and pharmaceuticals as priority contaminant groups in its draft Sixth Contaminant Candidate List (CCL 6), alongside PFAS, disinfection byproducts, and multiple chemicals and microbes. The list does not immediately impose regulations but serves as a critical scientific and policy tool to guide monitoring, research, and future regulatory decisions under the Safe Drinking Water Act. In parallel, the Department of Health and Human Services has launched a $144 million research initiative to study the health impacts of microplastics and develop methods for measuring and reducing exposure. EPA officials emphasised that the move responds to growing public concern and aims to build a stronger scientific foundation for protecting water quality nationwide. The initiative is expected to improve understanding of contamination risks and support long-term regulatory action to safeguard public health across the United States.
