From EcoWatch:

A team of researchers on Tuesday released a "blistering" report on the serious public health threats—from headaches to asthma to cancer—posed by hydraulic fracturing, or fracking, a process of injecting a mix of water and chemicals into rocks to release oil and natural gas.

The study—described as "the most authoritative" of its kind—was published by Concerned Health Professionals of New York and Physicians for Social Responsibility. Researchers found that "by several measures, evidence for fracking-related health problems is emerging across the United States and Canada."

Rolling Stone also covered the release of the study:

"Our examination . . . uncovered no evidence that fracking can be practiced in a manner that does not threaten human health," states a blistering 266-page report released today by Concerned Health Professionals of New York and the Nobel Peace Prize-winning group, Physicians for Social Responsibility. Drawing on news investigations, government assessments and more than 1,200 peer-reviewed research articles, the study finds that fracking – shooting chemical-laden fluid into deep rock layers to release oil and gas – is poisoning the air, contaminating the water and imperiling the health of Americans across the country.

Here is the study.
