ICYMI: EPA Takes Bold, Historic MAHA Action on Microplastics, Pharmaceuticals, and Potential Hidden Contaminants

April 6, 2026

WASHINGTON - On Thursday, April 2, 2026, alongside U.S. Department of Health and Human Services (HHS) Secretary Robert Robert F. Kennedy Jr., U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced landmark, coordinated actions to address microplastics contamination, one of the most urgent and growing public health challenges facing Americans. For the first time in agency history, EPA is including microplastics as a priority contaminant group in its draft Sixth Contaminant Candidate List (CCL 6), and is now holding a public comment period on it.

CCL 6 also includes pharmaceuticals as a group-another first-along with per- and polyfluoroalkyl substances (PFAS), disinfection byproducts, 75 individual chemicals, and nine microbes that may be present in public drinking water systems. Thursday's announcement, made at a press conference at EPA headquarters, represent a major step forward in President Trump's commitment to Make America Healthy Again.

"Health and Human Services Secretary RFK Jr. and EPA Administrator Lee Zeldin are declaring a war on microplastics. These tiny bits of plastic, which are less than 5 mm in size, can persist in our environment for hundreds or thousands of years. They may also build up in our bodies, our hearts and our brains, causing untold damage. For the first time, the EPA is adding microplastics and pharmaceuticals to its Contaminant Candidate List for drinking water, which will help to prioritize funding and pave the way for potential future regulation involving Congress."
