EPA Leaves Microplastics Off Draft Drinking-Water Monitoring List Amid Growing Scientific Alarm

Core Event
The Environmental Protection Agency (EPA) omitted microplastics from the draft list of unregulated contaminants that water utilities must monitor over the next five years. The decision, slated for finalization in the coming weeks, comes despite a recent *Lancet* editorial and calls from scientists and state officials for nationwide monitoring of plastic particles in drinking water.
Background & Context
On August 8, scientists published an editorial in *The Lancet* warning that plastics harm human health and ecosystems. The piece noted more than 16,000 chemicals used in plastic manufacture, including known carcinogens and endocrine disruptors. Microplastics—particles smaller than five millimeters—break down into nanoplastics that can carry these chemicals into human tissues. The authors reported detection of microplastics in oceans, Arctic ice, air, food, drinking water, and human organs.
Timeline
- Earlier this year – Health Secretary Robert F. Kennedy Jr. and EPA Administrator Lee Zeldin announced a $144 million research project to identify microplastics inside human bodies.
- Previously – The EPA placed microplastics on its draft Contaminant Candidate List, a five-year review that flags pollutants for potential regulation.
- Last year – Governors of New Jersey, Delaware, Illinois, Maryland, Michigan, Wisconsin, and Connecticut petitioned the EPA to require utilities to monitor microplastics.
- Mid-year – The EPA excluded microplastics from the draft list of pollutants that utilities must monitor, citing feasibility concerns.
- Recent weeks – The draft list is slated for finalization without mandatory monitoring requirements for microplastics.
Data & Statistics
- *Lancet*-cited studies indicate that U.S. tap water contains some of the highest microplastic concentrations globally.
- A 2026 volunteer effort removed over 1 million plastic pellets from waterways in 31 U.S. states and several foreign countries.
- An Ocean Conservancy poll released in June found that nearly nine in ten Americans are concerned about microplastics in the environment and food chain.
Official Statements & Responses
- The EPA says nationwide monitoring for microplastics in drinking water is not currently “feasible” and that more health-impact research is needed.
- EPA officials noted that inclusion of microplastics on the Contaminant Candidate List is a step toward future regulation, though utilities are not yet required to test for the particles.
- Kennedy Jr. and Zeldin described the $144 million research initiative as a “landmark, coordinated action.”
- The seven governors argued that monitoring is a critical first step toward enforceable drinking-water standards.
Verbatim Quotes
- “Policy doesn’t really need to wait for research to be 100 percent figured out. You can take precautionary action,” — Trisha Vaidyanathan, science director at Beyond Plastics
- “Their physical presence in the body can have an impact on your health — for example, as a foreign object in the body, it is likely triggering an immune response,” — Trisha Vaidyanathan
What’s Next
The EPA’s draft list will be finalized soon, determining whether microplastics become a required monitoring parameter for U.S. water utilities.
