"Helen Nez had 10 children. Now she only has three.

Seven of her children died of a disorder called Navajo neuropathy, which is linked to uranium contamination.

"Many people died and some have liver disease, kidney disease and some suffer from cancer as a result," Nez said through a translator.

When she was pregnant, Nez and her children drank from a spring, located on Navajo Nation in northeastern Arizona, with uranium levels at least five times greater than safe drinking water standards, according to a study published in the journal Environmental Science & Technology in 2015."
