In 2026, social media users claimed the U.S. Environmental Protection Agency put birth control and abortion pills on a water contamination "watch list."
The rumor spread on Instagram, Threads, Bluesky and TikTok.
The EPA did, in fact, put some birth control and abortion pills on a list (archived) called "2026 Human Health Benchmarks for Pharmaceuticals."
The list is meant to help state, tribal and local governments determine whether there are concerning levels of a pharmaceutical drug in their water systems. (There's no evidence abortion or birth control pills contaminate the country's water supply.)
According to the EPA, the benchmarks "are not rules or regulations and are not enforceable, and they are for contaminants that have no drinking water standards or health advisories." In an emailed statement, the EPA confirmed it does not consider the benchmarks list a "watch list."
Thus, we have rated this claim mostly true, as a "watch list"
In theory, the benchmarks cannot be used as a surveillance tool by itself. However, it could potentially lead to further regulation or surveillance, and states may use the list as guidance for developing their own policies.
"EPA takes the issue of pharmaceuticals in our water systems seriously and employs a rigorous, science-based approach to protect human health and the environment," the agency said in an email.
Here's a breakdown of what's happening:
EPA to prioritize pharmaceuticals for regulation
On April 2, 2026, the EPA said in a news release that it planned to target "microplastics and pharmaceuticals as priority drinking water threat groups."
In the news release, the EPA announced both a contaminant candidate list and the "human health benchmarks" list (emphasis ours):
At the heart of today's announcement is EPA's draft Sixth Contaminant Candidate List (CCL 6), which the agency is releasing for public comment, and is a critical tool under the Safe Drinking Water Act (SDWA) that drives research, funding, and future decisions on regulating emerging threats in public water systems.
[…]
- Pharmaceuticals, including antidepressants, hormones, antibiotics, and other drugs that enter water systems through human waste and improper disposal—are also being prioritized as a group for the first time. EPA is simultaneously releasing human health benchmarks for 374 pharmaceuticals, giving states, Tribes, and local water systems a critical new tool to assess risk and take action when drug residues are found at concerning levels.
[…]
The SDWA requires EPA to publish a list of contaminants every five years that are not subject to any proposed or promulgated national primary drinking water regulation, that are known or anticipated to occur in public water systems, and that may require regulation. The CCL is the first step in the SDWA regulatory process. The human health benchmarks for pharmaceuticals are not regulations and are not enforceable on their own, but they are a vital resource, empowering local decision-makers to evaluate risks and protect their communities when pharmaceutical contamination is detected at concerning levels.
In other words, the candidate contaminant list — which does not, as of this writing, feature birth control and abortion pills — includes pharmaceuticals that President Donald Trump's administration wants to regulate under the Safe Drinking Water Act.
In contrast, the human health benchmarks list — which does include some birth control and abortion medications — is meant to provide guidance to localities for safe drinking water. However, the human health benchmarks list is not an official step toward federal regulation of birth control and abortion medication in public water systems.
Birth control on non-regulatory list
Specifically, the human health benchmarks list includes misoprostol and methotrexate, both of which are used in medication abortions and for other health issues, as well as at least nine pharmaceutical drugs used in birth control:
- Desogestrel
- Drospirenone
- Ethinyl estradiol
Ethynodiol - Etonogestrel
- Levonorgestrel
- Norethindrone
- Norgestimate
- Norgestrel
For example, etonogestrel is used in a NuvaRing — a small flexible ring inserted into the vagina for birth control — and the common birth control brand
The list does not include mifepristone, the medication abortion often at the center of political furor over reproductive rights.
An analysis of the
As such, it appears that, for now, the Trump administration has put birth control and abortion medications only on a non-regulatory list. However, the contaminant list is not finalized, meaning it is subject to change.
Public comment on the contaminant list is due by June 5, 2026. As of May 6, the EPA has received more than 1,870 comments from the public.
Could 'watch list' be used as surveillance tool?
Concerns about the "watch list" being used as a surveillance tool may have originated with an Oct. 10, 2025, New York Times article, "The E.P.A. Followed Up on an Unusual Request About Abortion Pills." The Times reported that senior officials at the EPA responded to a request from 25 Republican members of Congress asking whether the government could develop methods of detecting traces of mifepristone in water.
According to the Times, several former EPA officials expressed concern about the potential for using this kind of drug detection for surveillance purposes in states where abortion is illegal.
"In an extreme case, the people said, wastewater testing could help identify a particular street or home where the pills were used, though such measures would be legally fraught and extremely costly," the Times reported.
The Times' report did not mention the human health benchmarks list or the contaminant list.
Other critics have also expressed concern about birth control and abortion pills on the human health benchmarks list being used for future regulation or surveillance. Sen. Ron Wyden, a Democrat from Oregon, accused the EPA in an April 20 letter of "[weaponizing] environmental regulations to push a backdoor ban on contraception and medications used for abortion care."
"While you claim these benchmarks are merely to 'empower local decision makers,' your own statements suggest a darker reality: this is laying the groundwork for sweeping state and federal restrictions on reproductive health care," Wyden wrote.
The Democrat also argued that the EPA's decision to open a public comment period for the contaminant list "despite the fact that this is not formal rulemaking" was "opening the door for extremists to flood the agency with demands to target mifepristone."
The EPA confirmed receipt of Wyden's letter in an email to Snopes and said it would "respond accordingly." The agency added that it has historically provided a public comment period and is required to by the Safe Drinking Water Act.
