Toxic Spill in the Navajo Nation

In August of 2015, 3 million gallons of acid mine drainage rushed into the Navajo Nation major water supply- the San Juan River. Karletta Chief, a University of Arizona hydrologist, and member of the Diné community, dedicated herself to finding ways to help communities contend with the spill and protect against future ecological disasters. Her research is featured in the new film titled Breakthrough: Bitter Water, which is a part of six-part anthology, Breakthrough: Portraits of Women in Science.
