No, your drinking water isn’t contaminated by abortion pills

mifepristone drinking – Anti-abortion groups and GOP lawmakers are urging the EPA to treat mifepristone as a water contaminant, but environmental health experts say there’s no scientific evidence it harms people or the environment. The push is gaining traction through coordinated let

On a May afternoon, Gen Z conservative influencer Isabel Brown posted an Instagram video that landed like a dare: the idea that when people fill a glass of water from the tap, they’re actually “drinking” someone else’s abortion.

Brown, who has more than 1 million followers, didn’t stop at the insinuation. In her video, she spoke with Kristan Hawkins, president of Students for Life of America, and contended that anti-abortion medication is “poisoning” the water.

The claim has been circulating for years. What’s changed is how aggressively it’s now being translated into policy—using environmental regulation as a vehicle for restricting medication abortion.

That effort reached a clear moment on June 5. when 14 Republican state attorneys general and 19 GOP lawmakers in Congress urged the Environmental Protection Agency to classify and regulate mifepristone as a water contaminant. arguing the drug is “a growing threat to the country’s waterways” and violates the Safe Drinking Water Act. One letter was signed by attorneys general of Alabama. Alaska. Arkansas. Florida. Idaho. Indiana. Kansas. Kentucky. Missouri. Nebraska. Louisiana. Oklahoma. South Carolina and Texas. The other letter was led by Republican Rep. Chris Smith of New Jersey and signed by 18 other GOP lawmakers.

Environmental health experts have consistently said there is no scientific evidence that abortion medication harms the environment—or humans. Reproductive rights advocates and environmental scientists say the movement’s narrative co-opts clean-water policy and weaponizes it alongside reproductive rights.

“This is really part of a broader effort to restrict access to medication abortion. ” said Anna Bernstein. principal federal policy adviser at the Guttmacher Institute. She said medication abortion has become the largest share of abortion care nationwide. with medication abortion accounting for 63 percent of all abortions in the United States in 2023. according to Guttmacher Institute data.

The question lawmakers are pressing into the EPA’s process is stark: do oral abortion pills really end up in drinking water?

Anti-abortion advocates argue that over 50 tons of medical waste—including blood. placental tissue. and human remains—are flushed into water systems each year as a result of these drugs. They also claim that high concentration of elements of mifepristone in water—specifically a hormone called progesterone—can disrupt and reduce fertility in women. They argue that previous results of federal testing of mifepristone’s environmental impact are outdated.

Environmental health experts reject those claims. Nathan Donley. the environmental health science director at the Center for Biological Diversity. pointed out that mifepristone is used by a small fraction of the population and is typically taken as a one-time dose. He also noted that many pharmaceuticals taken daily by tens of millions of Americans enter wastewater systems in far greater quantities. Donley said mifepristone was not included among nearly 700 pharmaceutical compounds the EPA previously screened for potential water contamination concerns.

Donley described the push as a pretext. While he said proponents are seeking to add mifepristone to the EPA’s 6th Contaminant Candidate List (CCL6)—a preliminary list of substances that could potentially be considered for future drinking water regulation—adding a substance to the list would not itself regulate the drug. Placement, he said, could instead begin a lengthy review process.

He also argued that attention on mifepristone distracts from well-documented threats like PFAS—known as forever chemicals—pesticides, lead, and nitrate contamination.

“There are legitimate water quality threats that we need to attack and rectify in a regulatory manner. And then there are things that are out in the left field that just distract people,” Donley said.

The policy push doesn’t come from nowhere. In 1996, the Food and Drug Administration tested for the environmental effects of mifepristone and found “no significant impact.” In the June letter, lawmakers cite the FDA study and urge “reconsideration” of potential harm to the environment.

After the Supreme Court’s 2022 decision in Dobbs v. Jackson Women’s Health Organization eliminated the federal constitutional right to abortion. opponents increasingly focused on limiting access to abortion medication and prescribing it through telehealth. which has become a critical pathway for people living in states with abortion bans.

But anti-abortion groups have also ramped up efforts during the second Trump administration to push mifepristone toward formal environmental classification. Last November. Students for Life of America met with the EPA to advocate for adding mifepristone to the CCL6 as the agency carried out a routine update to a separate list of health benchmarks for pharmaceuticals that must be tracked in drinking water.

The June letters were timed toward an EPA comment period tied to that process. The comment window began in April and allowed members of the public to submit their thoughts on draft proposals reviewed by the agency. In public statements posted by the anti-abortion group. Students for Life of America argued that “You don’t have to be pro-life to want clean drinking water” and that people should be concerned about being “microdosed” by progesterone blockers. which it called a factor in rising infertility.

On its website, the group also said it asked that mifepristone be tracked “given the reasonable cause for concern that regular and ongoing exposure to a progesterone blocker is impacting public health, endangered species, and the environment,” and said it planned to take on the issue in every state.

The campaign included significant public participation. Students for Life of America said it collected over 1. 700 public comments to send to the EPA and helped spearhead the 14-state campaign of letters from attorneys general ahead of the public comment period for the CCL6. Public records show the draft for the CCL6 received nearly 22,000 public comments before closing on June 5.

Anti-abortion lawmakers aren’t limiting their efforts to federal classification. In 2025, according to the Guttmacher Institute, anti-abortion policymakers introduced nine bills in seven states tying medication abortion to water pollution. That same year, 25 members of Congress sent a similar letter asking the EPA to monitor for environmental harms of mifepristone. In March, U.S. Rep. Mary Miller. a Republican from Illinois. introduced a Clean Water for All Life Act. citing similar claims about environmental degradation from abortion medication.

Bernstein and Guttmacher state policy adviser Kimya Forouzan said proposals vary. but several focus on forcing new kinds of testing and procedures. Some would require state agencies to test wastewater for abortion medications. Others would require patients to use so-called “catch kits” and medical waste bags to collect and return pregnancy tissue after taking abortion medication. Some bills would also create liability for drug manufacturers if abortion medications were detected in wastewater.

While the specific mechanics differ, Bernstein said the structure points toward a common result: federal benchmarks that feed into monitoring at the local level.

“The CCL is one part of a broad regulatory process. This draft list is then used to inform another list. which determines which contaminants are monitored and regulated. but the surveillance really does happen at a municipality and then state level. ” Bernstein said. “So this would be setting federal benchmarks for localities to monitor in their wastewater.”.

To date. neither President Donald Trump nor EPA chief Lee Zeldin has explicitly spoken about any health risks of mifepristone in water. Bernstein said the administration’s silence could increase pressure from anti-abortion advocates. particularly when they are frustrated at perceived lack of action from the Trump administration.

“We anticipate that disinformation campaigns surrounding mifepristone. including these false claims on the environmental impact. will continue to escalate — particularly as abortion opponents are frustrated at a perceived lack of action by the Trump administration. ” Bernstein told The 19th. She also said. “We know. however. that restricting access to abortion is politically unfavorable. and candidates may be hesitant to focus on these efforts before the midterm elections.”.

For people trying to get care, the fight is not abstract.

After Dobbs. Forouzan said medication abortion became a “lifeline” for many people seeking care. especially through telehealth providers operating under shield laws—state-by-state legal protections designed to safeguard practitioners from being sued by states with abortion bans. She said anti-abortion officials at the state and federal level have increasingly focused on restricting the remaining ways people can access abortion care.

Forouzan said monitoring abortion medication in wastewater contributes to a broader “culture of surveillance.” She raised concerns that data from such monitoring could be used to increase scrutiny of people who obtain medication abortions.

That surveillance framing is also how reproductive advocates describe the stakes as the policy campaign expands. On the anniversary of Dobbs, Rep. Brittany Pettersen. a Democrat from Colorado. submitted a resolution urging action against the disinformation campaign. saying water systems should “not be weaponized for the purposes of surveilling. tracking. or detecting use of. stigmatizing. and further restricting access to medication abortion care.”.

Advocates have also pointed to a contradiction they see in how lawmakers treat different hazards. In Indiana. where the state’s attorney general co-signed the June letter. state lawmakers recently passed legislation to deregulate the Indiana Department of Environmental Management. the agency charged with limiting pollution in the state’s air. water and soil.

Even as the mifepristone debate moves through comment periods, the EPA has already taken steps toward broader pharmaceutical monitoring. In April, the agency released a list of 374 drugs that states should monitor. The list did not include mifepristone, but it did include other medications used in abortions such as misoprostol and methotrexate. Both are used in daily birth control and the NuvaRing contraceptive. An April press release said it was the first time the agency designated pharmaceuticals as a contaminant group.

The EPA did not respond to The 19th’s request for comment.

The federal timeline now hinges on what happens after the June comment period. The EPA’s comment period allowed 60 days for the public to weigh in on the list before agency staff began reviewing feedback and finalizing. With the June comment period closed, whether the agency will ultimately add mifepristone to the list remains uncertain.

But Bernstein said when federal regulators previously reviewed environmental concerns related to mifepristone, they found no evidence warranting restrictions.

The push also reflects how quickly state politics can echo into federal proposals. Bernstein and Forouzan said anti-abortion states and lawmakers often learn from each other in order to pass bills in their respective states. working “parallel” to federal bill proposals with the same goal: restricting access to mifepristone and rolling back requirements that force in-person dispensation—requirements that. Forouzan said. would limit access to a wide range of people.

Four years after Dobbs, reproductive advocates say anti-abortion campaigns have evolved to “severely restrict” access to care across the country. Guttmacher Institute reports that 13 states enforce total bans and 6 explicitly prohibit telehealth use to provide abortion pills.

In Bernstein’s account, wastewater monitoring proposals are part of a broader process that risks making myths feel like policy while expanding fear for patients.

“It’s contributing to this culture of surveillance around medication abortion at a time when that is already increasing,” Bernstein said. “And folks, especially in banned states, are facing increasing fear of criminalization.”

She added that there are concerns the monitoring effort could eventually be used for the criminalization of patients, while also creating broader restrictions on mifepristone and perpetuating the myths.

For Brown’s followers, the idea is packaged as a simple question—whether your tap water carries someone else’s abortion. For lawmakers and advocates pushing the EPA, it’s not just a claim. It’s a route into regulatory action.

And for scientists and reproductive health experts, the bottom line is plain: there is no scientific evidence to support the contamination narrative—no evidence that mifepristone is harming the environment or people in the way the campaign suggests.
