Should the government test drinking water for pharmaceutical residues like medications?
The EPA announced on September 9, 2026 that it will test water supplies for mifepristone and misoprostol. The screening covers more than 1,400 pharmaceuticals, pesticides, and other chemicals, separate from testing for unregulated contaminants under the Safe Drinking Water Act.
Why it matters
The EPA said the testing aims to improve understanding of what pollutants may be present in drinking water, a question that affects utilities and the public across the United States. Anti-abortion groups, including Students for Life of America, had lobbied the agency for more than a year to investigate.
The EPA's screening program covers more than 1,400 pharmaceuticals, pesticides, and other chemicals, including testosterone, progesterone, and levonorgestrel. Results for the listed substances have not yet been released, and the scope of detections remains unknown.
The players
Environmental Protection Agency
The federal agency responsible for setting and enforcing national drinking water standards under the Safe Drinking Water Act.
Students for Life of America
An anti-abortion advocacy organization that lobbied the EPA for more than a year to investigate abortion-related drugs in water.
The details
The screening will include testosterone, progesterone, and levonorgestrel, the last of which is used in contraceptives such as Plan B. The EPA framed the effort as a way to improve understanding of pollutants in drinking water rather than as a response to a specific contamination event.
Timeline

Utilities Context
The screening runs parallel to the Safe Drinking Water Act's framework for regulated and unregulated contaminants, extending federal water monitoring to a broader set of pharmaceuticals than that framework typically covers. Whether this testing leads to new standards under the Act has not been stated.
Households drawing water from public systems may eventually see results of this testing reported by utilities or the EPA. Current results for the listed substances have not been released, so no immediate change to tap water is indicated.
The takeaway
Federal water testing is expanding beyond traditional contaminants, and readers can watch for published EPA results to understand what is actually detected. Results will clarify whether the screening reveals a practical concern for drinking water.
