The lead-poisoned water in Flint, Michigan, may have caused a "horrifyingly large" rise in fetal deaths in the city.
In 2014, Flint switched its water source to the Flint River. Corrosion caused lead from the city's aging water pipelines to seep into the water supply.
Now, a study says fetal death rates in Flint increased by 58 percent compared to other Michigan cities after the switch. Fertility rates in Flint also dropped 12 percent.
The study's authors called it a "culling of the least healthy fetuses," and estimate between 198 and 276 more babies would have been born if not for the change in water supply.
What's more, the researchers think their estimates could be low. The results don't include abortions or miscarriages before 20 weeks, and the data only includes deaths reported by hospitals.
The study comes at a time when the Environmental Protection Agency faces major budget cuts. The researchers said they hope it will show the government how important water regulations are to public health.
