Of the states examined, North Dakota had the highest rate of spills, with 4,453 incidents.
New regulations on oil drilling in different parts of Oklahoma have reportedly significantly reduced the frequency of quakes and tremors in the state. This seems to prove that thousands of tremor "swarms" or quakes experienced in different areas, having magnitudes as high as 5.0, are actually man-made.
A new study from the University of Calgary revealed that injecting fluid deep underground could buildup enough stress to produce periodic earthquakes that can last for months after the fracking operations have stopped.
Fracking could be responsible for the heightened concentrations of some common compounds in the drinking water wells near the drilling site.
Researchers suggest a new monitoring method to assess the pressure caused by wastewater disposals, in which could result to an earthquake.
A new study from the Ohio State University revealed a never-before-seen genus of bacteria believed to be unique in shale oil and gas wells made by hydraulic fracturing.
A new study reveals that chemicals used during hydraulic fracturing or fracking are not only dangerous to the environment but can also have a negative impact in reproductive system and development.
A new study revealed that those living near fracking sites are four times more at risk of having asthma attacks.
British actress Emma Thompson, along with her sister Sophie, broke court injunction to protest against fracking on a Lancashire site.
Yale researchers have confirmed that removing natural gas from deep underground using hydraulic fracturing methods does not contaminate drinking water, although they also said that "geology across the country is very different."
In an update on the past couple of years in energy extraction, studies, and fracking in North America, we look at what Nature World News has said and studies have covered.
A Duke University study provides the first comprehensive assessment of fracking's total water footprint.
Currently, the U.S. has 989 open and closed landfills, which amounts to a great deal of methane leaking from all that piled waste. The EPA's recent proposal seeks to regulate the emissions of at least 574 of those. The proposals also address controlling fracking emissions.
It's no secret that fracking has been associated with earthquakes, contaminated groundwater and increasing levels of toxic radon, but now researchers are adding air quality and human health to the list.
