アメリカ環境保護庁（EPA）は、飲用水中の MICROPLASTICS（マイクロプラスチック）と PHARMACEUTICALS（薬物）を新たに含む水質汚染物質の暫定リストを作成し、公衆衛生上の懸念に対応するため発表しました。この決定は「Make America Healthy Again」運動における歴史的なステップ」として位置づけられました。また、アメリカ保健労働省（HHS）は「STOMP」計画を発表し、飲用水中のマイクロプラスチックの測定や監視を目的とした1億4400万ドルの予算を投入することを明らかにしました。
Safe Drinking Water Actに基づき、EPAは毎5年ごとにContaminant Candidate List（CCl）を更新しなければならないと規定されており、このリストにはPFASなど多くの化学物質や微生物も含まれています。これらの物質が暫定リストに含まれることにより、地元の規制当局は飲用水中のリスク評価を行うためのツールを得ますが、具体的な規制措置が講じられる保証はありません。
An anonymous reader quotes a report from NPR: Responding to public health concerns about microplastics and pharmaceuticals in the nation's drinking water, the Trump administration for the first time has placed them on a draft list of contaminants maintained by the Environmental Protection Agency. The EPA announced the move Thursday, touting it as a "historic step" for the Make America Healthy Again, or MAHA, movement, which often raises concerns about toxic chemicals and plastic pollution in our food and environment. Also Thursday, the Department of Health and Human Services announced a $144 million initiative, called STOMP, to develop tools to measure and monitor microplastics in drinking water and in a later stage, to remove them.
The Safe Drinking Water Act requires the EPA to publish an updated version of its Contaminant Candidate List every five years. This is the sixth iteration of the list. Microplastics and pharmaceuticals appear in the draft of the upcoming list, alongside per- and polyfluoroalkyl substances, or PFAS, and dozens of other chemicals and microbes. Their inclusion on the list gives local regulators a tool to evaluate risks in their water supply, the EPA says, and it can set the stage for more research and regulatory action -- but doesn't actually guarantee that will happen.
