Groundwater unaffected by shale gas production in Arkansas
A new study by scientists at Duke University and the U.S. Geological Survey (USGS) finds no evidence of groundwater contamination from shale gas production in Arkansas.
Fracking brings economic boost, but risks raise concerns
Most Michigan and Pennsylvania residents say fracking is good for the economy, but have concerns about chemicals used and other environmental risks, according to a University of Michigan survey.
Physical chemistry could answer many questions on fracking
Another tiny miracle: Graphene oxide soaks up radioactive waste
(Phys.org)—Graphene oxide has a remarkable ability to quickly remove radioactive material from contaminated water, researchers at Rice University and Lomonosov Moscow State University have found.
Methane levels 17 times higher in water wells near hydrofracking sites
A study by Duke University researchers has found high levels of leaked methane in well water collected near shale-gas drilling and hydrofracking sites. The scientists collected and analyzed water samples from 68 private ...
US methane report further divides fracking camps
The U.S. Environmental Protection Agency has dramatically lowered its estimate of how much of a potent heat-trapping gas leaks during natural gas production, in a shift with major implications for a debate that has divided ...
Fracking leaks may make gas 'dirtier' than coal
(PhysOrg.com) -- Extracting natural gas from the Marcellus Shale could do more to aggravate global warming than mining coal, according to a Cornell study published in the May issue of Climatic Change Letters (105:5).
Energy industry develops nontoxic fracking fluids
The oil and gas industry is trying to ease environmental concerns by developing nontoxic fluids for the drilling process known as fracking, but it's not clear whether the new product will be widely embraced by drilling companies.
Study ties oil, gas production to Midwest quakes
Oil and gas production may explain a sharp increase in small earthquakes in the nation's midsection, a new study from the U.S. Geological Survey suggests.
Analysis of fracking wastewater yields some surprises
Hydraulically fractured natural gas wells are producing less wastewater per unit of gas recovered than conventional wells would. But the scale of fracking operations in the Marcellus shale region is so vast that the wastewater ...
US carbon emissions in surprise drop
US emissions of carbon dioxide blamed for climate change fell in 2011 and have slipped to a 20-year low this year as the the world's largest economy uses more natural gas and less coal, data shows.
No matter the drilling method, natural gas is a much-needed tool to battle global warming: study
No matter how you drill it, using natural gas as an energy source is a smart move in the battle against global climate change and a good transition step on the road toward low-carbon energy from wind, solar and nuclear power.
Researchers challenge study on hydrofracking's gas footprint
(PhysOrg.com) -- A Cornell study's contention that hydraulic fracturing would be worse for climate change than burning coal is being challenged by another study, also by Cornell researchers.
Marcellus brine migration likely natural, not man-made: study
A Duke University study of well water in northeastern Pennsylvania suggests that naturally occurring pathways could have allowed salts and gases from the Marcellus shale formation deep underground to migrate ...
