While water contamination from all pharmaceuticals is a growing concern, there is no evidence that abortion pills are harming the water supply or are harmful to people.

Nathan Donley, the environmental health science director at the Center for Biological Diversity, told the outlet mifepristone is not one of the known contaminants on the EPA's list to regulate.

“There are major water contaminants that need to be regulated, and testing for those things can be good as long as regulation happens. And then on the other hand, if we’re wasting time on a witch hunt for... those things like mifepristone, then that’s time and resources we take away from regulating and studying things that that are actually a problem,” Donley said.
