Is Fracking For Gas Dirty Enough For A Coal Resurgence?

Tougher environmental regulations, a flood of cheap natural gas from fracking, and a sudden decrease in demand from China, has pushed natural gas even further in replacing coal in generating electricity. But fears about fracking’s effects on the environment has spawned bans on fracking in some states. A new study by the University of Texas at Arlington demonstrates that groundwater quality changes alongside the expansion of horizontal drilling and hydraulic fracturing but also suggests that some potentially hazardous effects may dissipate over time.
