Hydraulic Fracturing Poses Substantial Water Pollution Risks, Analysts Say
ScienceDaily (Aug. 6, 2012) — Risk analysts have concluded that the disposal of contaminated wastewater from hydraulic fracturing (or "fracking") wells producing natural gas in the intensively developed Marcellus Shale region poses a substantial potential risk of river and other water pollution. That conclusion, the analysts say, calls for regulators and others to consider additional mandatory steps to reduce the potential of drinking water contamination from salts and naturally occurring radioactive materials, such as uranium, radium and radon from the rapidly expanding fracking industry. The new findings and recommendations come amid significant controversy over the benefits and environmental risks associated with fracking. The practice, which involves pumping fluids underground into shale formations to release pockets of natural gas that are then pumped to the surface, creates jobs and promotes energy independence but also produces a substantial amount of wastewater.
