A new study by the Department of Energy shows fracking doesn't hurt the environment.
Fracking is a process for extracting natural gas from deep down below the ground. It's become an easier, more efficient way to create energy, but environmentalists say it's dangerous to drinking water.
However, the study shows that the toxic chemicals used to get the natural gas out of the ground stayed way below the level where we get our drinking water.
In fact, they remained a full mile below the drinking water supply.
The study was conducted for a full year near Pittsburgh.
