Substances commonly used for drilling or extracting Marcellus shale gas foamed from the drinking water taps of three Pennsylvania homes near a reported well-pad leak, according to new analysis from a team of scientists.
The United States is seeing a natural gas boom thanks to discoveries of abundant shale gas, and at the same time a groundswell of opposition from critics who say the environmental risks from drilling are too great.
(PhysOrg.com) -- The pace and extent of Marcellus Shale development across Pennsylvania can be "seen" in animated maps produced by the Penn State Marcellus Center for Outreach and Research.
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 ...
(AP) -- The U.S. Environmental Protection Agency announced Thursday for the first time that fracking - a controversial method of improving the productivity of oil and gas wells - may be to blame for causing groundwater pollution.
Underneath the ground in southwestern Pennsylvania, bedrock is put under explosive pressure to fracture and spill out its lucrative cache of natural gas.
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 up into shallow ...
(Phys.org)—Researchers have made a genetic analysis of the microbes living deep inside a deposit of Marcellus Shale at a hydraulic fracturing, or "fracking," site, and uncovered some surprises.
Homeowners living within one kilometer of shale gas wells appear to be at higher risk of having their drinking water contaminated by stray gases, according to a new Duke University-led study.
