No, your drinking water isn’t contaminated by abortion pills
Anti-abortion advocates, including Republican lawmakers and state officials, want the EPA to review mifepristone as a water contaminant.
By Jenae Barnes for The 19th
Anti-abortion advocates, including Republican lawmakers and state officials, want the EPA to review mifepristone as a water contaminant. Scientists say there’s no evidence it harms the environment or people.
While there is no scientific evidence that abortion medication is contaminating Americans’ water supply, it has nonetheless become a central claim by the anti-abortion movement. Activists, Instagram influencers and Republican Party officials — including state and federal lawmakers — are doubling down on what experts describe as a disinformation campaign that mixes environmental policy and reproductive rights, and risks exploiting legitimate concerns about clean water.
“What if I were to tell you that every time you fill up a glass of water at your kitchen sink from the tap, you were actually *drinking* someone else’s abortion,” influencer Isabel Brown wrote in an Instagram post in May. In the accompanying video, the Gen Z conservative content creator, who has more than 1 million followers on her platform, talks to Kristan Hawkins, president of Students for Life of America, a national anti-abortion organization, and contends that anti-abortion medication is “poisoning” the water.
The claim isn’t new. For decades, anti-abortion advocates have argued that abortion medications, primarily mifepristone, pollute the environment and put pregnant people’s health at risk. But the argument has now become part of a widespread and often coordinated effort to create federal and state policy that further suppresses abortion access.
On June 5, 14 Republican state attorneys general and 19 GOP lawmakers in Congress urged the Environmental Protection Agency (EPA) to classify and regulate mifepristone as a water contaminant. In two concurrent letters, officials argued that the abortion medication, part of a safe and effective two-drug regimen to terminate pregnancies, 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, led by Republican Rep. Chris Smith of New Jersey, made similar claims and was signed by 18 other GOP lawmakers.
Environmental health experts have consistently said there is no scientific evidence that abortion medication causes harm to the environment — or to humans. Both reproductive rights advocates and environmental scientists have said that the argument co-opts environmental policy as a pathway to weaponize and stigmatize health care.
“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, a research organization that supports reproductive rights. She said anti-abortion activists are increasingly turning to “every lever they can” as medication abortion has become the largest share of abortion care nationwide. Medication abortion accounted for 63 percent of all abortions in the United States in 2023, according to Guttmacher Institute data.
Does oral abortion medication really end up in drinking water?
Anti-abortion advocates contend 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 argue high concentration of the elements of mifepristone in water, specifically a hormone called progesterone, disrupts and reduces fertility in women. They also say that previous results of federal testing of mifepristone’s environmental impact are outdated.
Environmental health experts dismiss these claims. These experts consistently point out that there is no scientific basis for treating mifepristone or other abortion medication as a water contaminant. 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. By comparison, many pharmaceuticals taken daily by tens of millions of Americans enter wastewater systems in far greater quantities. He also noted that mifepristone was not included among nearly 700 pharmaceutical compounds the EPA previously screened for potential water contamination concerns.
Instead, Donley described the effort as an attempt to use environmental concerns as a pretext for limiting reproductive rights. He noted that while 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, placement on the list would not itself regulate the drug but could begin a lengthy review process.
Donley added that focusing on mifepristone distracts from well-documented water quality threats, including 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.
Where did this argument come from and why is it gaining traction again now?
In 1996, the Food and Drug Administration (FDA) 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.
Since the Supreme Court’s 2022 decision in Dobbs v. Jackson Women’s Health Organization eliminated the federal constitutional right to abortion, opponents have 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 ramped up efforts during the second Trump administration to advocate for the official classification of mifepristone as a water contaminant.

Last November, Students for Life of America (SFLA), a national anti-abortion group, 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 coordinated letters in June were timed toward the EPA’s 60-day comment period, which began in April and allowed members of the public to submit their thoughts on draft proposals to be reviewed by the agency.
“SFLA asks 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,” the anti-abortion group said in a statement on their website, adding that the group plans to take on the issue in every state. “You don’t have to be pro-life to want clean drinking water. You don’t have to be pro-life to be concerned that we are being ‘microdosed’ by progesterone blockers, which are a factor in rising infertility.”
The SFLA 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 to the EPA ahead of its public comment period for the CCL6.
The draft for the CCL6 received nearly 22,000 public comments before closing on June 5, public records show.
How are lawmakers trying to change environmental abortion policies?
In 2025, anti-abortion policymakers introduced nine bills in seven states tying medication abortion to water pollution, according to the Guttmacher Institute. That same year, 25 members of Congress sent a similar letter asking the EPA to monitor for environmental harms of mifepristone. This March, U.S. Rep Mary Miller, a Republican from Illinois, introduced a Clean Water for All Life Act, citing similar claims of environmental degradation from abortion medication.
According to Bernstein and Guttmacher state policy adviser Kimya Forouzan, some proposals 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 create liability for drug manufacturers if abortion medications were detected in wastewater.

While the bills vary, abortion rights advocates say they share a common goal: creating additional barriers to medication abortion access.
“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, adding: “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 have explicitly spoken to any health risks of mifepristone in water. But the president and leading administration officials’ decision to stay silent on the issue may increase pressure from anti-abortion advocates, according to Bernstein.
“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. “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.
What are the stakes for pregnant people?
As abortion rights and access have shrunk, Forouzan said that medication abortion has become a “lifeline” for many people seeking care after Dobbs, particularly through telehealth providers operating under shield laws, which are state-by-state legal protections to safeguard practitioners from being sued by states with abortion bans. As a result, anti-abortion officials at the state and federal level have increasingly focused on restricting the remaining ways people can access abortion care.
Forouzan said the push to monitor abortion medication in wastewater contributes to a broader “culture of surveillance” surrounding abortion. She said proposals to test wastewater for mifepristone raise concerns about how such monitoring data could eventually be used and whether it could increase scrutiny of people who obtain medication abortions.
Do these claims have the potential to impact federal policy?
The potential of environmental harms continues to shape policy for abortion and anti-abortion advocates. On the anniversary of Dobbs, Rep. Brittany Pettersen, a Democrat from Colorado, submitted a resolution to address the disinformation campaign, saying that 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 also point to what they see as a contradiction in the campaign. Many of the same advocates and elected officials who support mifepristone monitoring have opposed other environmental hazard regulations. For example, in Indiana, where the state’s attorney general co-signed the letter, state lawmakers recently passed legislation to deregulate the Indiana Department of Environmental Management, an agency in charge of limiting pollution in the state’s air, water and soil.
The EPA has already taken action to recommend states begin testing drinking water for abortion medications. In April, the agency released a list of 374 drugs that states should monitor. While it does not include mifepristone, it does include other medications used in abortions such as misoprostol and methotrexate, commonly used in daily birth control and the NuvaRing contraceptive. It’s the first time the agency has designated pharmaceuticals as a contaminant group, according to an April press release.
The EPA did not respond to The 19th’s request for comment.
The EPA’s comment period allowed 60 days for the public to weigh in on the list before agency staff began reviewing the feedback and finalizing. Now that the June comment period has closed, whether the agency will ultimately add the medication to the list remains uncertain. However, when federal regulators previously reviewed environmental concerns related to mifepristone, they found no evidence warranting restrictions, according to Bernstein.
Bernstein and Forouzan said that anti-abortion states and lawmakers often learn from each other in order to pass bills in their respective states. Forouzan added these efforts work “parallel” to federal bill proposals, both with the same goal: to restrict further access.
“Its really just to restrict access to mifepristone and specifically to roll back requirements to force in-person dispensation, which would really limit access to a lot of folks.”
Four years after the Supreme Court’s decision in Dobbs, reproductive advocates say the evolution of anti-abortion campaigns continue to “severely restrict” access to care across the country. Thirteen states currently enforce total bans, and 6 explicitly prohibit telehealth use to provide abortion pills, according to Guttmacher Institute.
“It’s contributing to this culture of surveillance around medication abortion at a time when that is already increasing, and folks, especially in banned states, are facing increasing fear of criminalization,” Bernstein said. “There are concerns whether it will be eventually used for the criminalization of patients, in addition to creating a broader restriction of mifepristone and perpetuating these myths.”
