In July, the U.S. Department of Energy (DOE) released preliminary results from its study on hydraulic fracturing (fracking) in the Marcellus Shale formation of Pennsylvania, stating that fracking chemicals do not cause water pollution, according to the Associated Press.
After a year of monitoring the aquifer located near the drilling site, DOE researches found no traces of the fluids laced with marker chemicals and injected thousands of feet below the services.
For both skeptics and optimists out there, I would like to point out that the study is not final and fracking has yet to receive a clean bill of health when it comes to groundwater pollution, not to mention various other concerns.
From new jobs to energy security, natural gas plays a key role in our nation's clean energy future. That said, environmental concerns must be addressed first and foremost, and I believe more research is needed to better understand any potential impacts of fracking on drinking water resources.
