Michael Bastasch reports that a landmark U.S. DOE study found no evidence that hydraulic fracturing better known as fracking contaminated drinking water in western Pennsylvania. The DOE monitored wells for a year by injecting special tracers into fracking fluid to see whether any chemicals migrated up towards drinking water.
Researchers found that the fracking fluid stayed nearly a mile below drinking water supplies.The U S Environmental Protection Agency also has failed to find evidence of drinking-water contamination in three separate studies. The agency is currently in the process of conducting a larger national study that will be done in 2016.
