To direct the Administrator of the Environmental Protection Agency to include certain nanoplastics and microplastics on a certain list of unregulated contaminants published pursuant to the Safe Drinking Water Act, and for other purposes.
Key claim: The bill would require EPA to put certain nanoplastics and microplastics on the Safe Drinking Water Act list of unregulated contaminants, the first step toward requiring public water systems to monitor for them.
Abstract
(HR10947 · 119th Congress) Latest action (2026-10-29): Referred to the House Committee on Energy and Commerce.
Why this matters
Adding nano- and microplastics to the SDWA unregulated contaminants list would be the first federal step toward routine occurrence data at public water systems — a prerequisite under the Safe Drinking Water Act before EPA can consider a national drinking water standard. The practical near-term effect is monitoring cost and lab-method development for utilities rather than treatment upgrades, but the data generated typically drives later regulatory determinations.
