Fracking waste can be radioactive. Advocates want it included in a pair of state-sponsored studies into fracking and childhood cancer, asthma, and poor birth outcomes.
As fires burn longer and closer to cities throughout the West, researchers are trying to understand the lasting health impacts by studying a Montana town previously smothered by wildfire smoke.
The study found an estimated 26,000 lives were saved by replacing coal with natural gas, but health impacts from fracking weren't considered in the study.
