unconventional oil and gas extraction
In 2015, the U.S. Environmental Protection Agency released a report finding 457 fracking-related spills in eight states between 2006 and 2012. Last month, a new study tallied more than 6,600 fracking spills in just four states between 2005 and 2014. But, as usual, the numbers only tell part of the story.
Not every spill counted in that new number represents a spill of potentially harmful materials or even a spill that made contact with the environment. In fact, the study’s goal wasn’t to tally an absolute number of fracking spills. Instead, researchers set out to collect available spill data…
In a new study — the first of its kind — researchers fed water laced with fracking chemicals to pregnant mice and then examined their female offspring for signs of impaired fertility. They found negative effects at both high and low chemical concentrations, which raises red flags for human health as well.
“These are preliminary findings,” Susan Nagel, the study’s senior author and an associate professor in Obstetrics, Gynecology and Women’s Health at the University of Missouri School of Medicine, told me. “But I think they suggest that we should absolutely be looking more closely at the…
A recent study of air quality around unconventional oil and gas extraction sites — more commonly referred to as fracking — found high levels of benzene, hydrogen sulfide and formaldehyde, all of which pose risks to human health. But what makes this study particularly interesting is that the air samples were collected by the very people who live near the extraction sites, and the collection times were specifically triggered by the onset of health symptoms.
Published yesterday in the journal Environmental Health, the study involved residents living near 11 unconventional extraction sites in…
