The pollution comes from both hydraulic fracturing (fracking) and conventional drilling methods to extract petroleum and natural gas.
Along with carbon dioxide, methane is one of the most important greenhouse gases in terms of its potential to raise global temperatures.
New testing of treated wastewater from fracking shows that it contains high levels of radioactive radium, along with chloride and bromide.
Humans almost certainly cause global warming, scientific panel says.
DeSmogBlog has obtained a copy of an Obama Administration Environmental Protection Agency (EPA) fracking groundwater contamination PowerPoint presentation describing a then-forthcoming study's findings in Dimock, Pennsylvania.
A must-read Los Angeles Times story by Neela Banerjee demonstrates that - once again - the Obama administration put the kibosh on a key Environmental Protection Agency (EPA) study on hydraulic fracturing ("fracking") groundwater contamination, this time in Dimock, Pennsylvania.
When the Environmental Protection Agency abruptly retreated on its multimillion-dollar investigation into water contamination in a central Wyoming natural gas field last month, it shocked environmentalists and energy industry supporters alike.
President Barack Obama announced his administration's "Climate Action Plan" for cutting carbon pollution in his second term in the Oval Office at Georgetown University and unfortunately, it's a full-throttle endorsement of every aspect of fracking and the global shale gas market.
Last week, the U.S. Environmental Protection Agency (EPA) kicked the can down the road on a key study designated to examine the connection between hydraulic fracturing ("fracking") and groundwater contamination in Pavillion, Wyoming.
