West Virginia groundwater not affected by fracking, but surface water is

Fracking has not contaminated groundwater in northwestern West Virginia, but accidental spills of fracking wastewater may pose a threat to surface water in the...

Anticipating hazards from fracking-induced earthquakes in Canada and US

As hydraulic fracturing operations expand in Canada and in some parts of the United States, researchers at the 2017 Seismological Society of America's (SSA)...

Study reveals two seismic processes by which hydraulic fracturing induces tremors

In some parts of western Canada, small-to-moderate earthquakes have been induced by oil and gas hydraulic fracturing operations. In Alberta, this type of induced...

Study links groundwater changes to fracking

A new study has found heightened concentrations of some common substances in drinking water near sites where hydraulic fracturing has taken place. The substances...

Research finds way to make fracking safer

Study finds that wastewater injections cause man-made earthquakes, but the risk can be reduced through monitoring Injecting wastewater deep underground as a byproduct of oil...

Hydraulic fracturing chemical spills on agricultural land need scrutiny

Hydraulic fracturing, a widely used method for extracting oil and gas from otherwise impenetrable shale and rock formations, involves not only underground injections composed...

Hydraulic fracturing

Oil and natural gas, which are hydrocarbons, reside in the pore spaces between grains of rock (called reservoir rock) in the subsurface. If geologic...

Some gas produced by hydraulic fracturing comes from surprise source

San Francisco--Some of the natural gas harvested by hydraulic fracturing operations may be of biological origin--made by microorganisms inadvertently injected into shale by oil...
