Monitoring in Fracking Areas Fails To Detect Air Toxic Spikes: Study

"People in natural gas drilling areas who complain about nauseating odors, nosebleeds and other symptoms they fear could be caused by shale development usually get the same response from state regulators: monitoring data show the air quality is fine. A new study helps explain this discrepancy. The most commonly used air monitoring techniques often underestimate public health threats because they don’t catch toxic emissions that spike at various points during gas production, researchers reported Tuesday in the peer-reviewed journal Reviews on Environmental Health. The study was conducted by the Southwest Pennsylvania Environmental Health Project, a nonprofit based near Pittsburgh.

A health survey the group released last year found that people who live near drilling sites in Washington County, Pa., in the Marcellus Shale, reported symptoms such as nausea, abdominal pain, breathing difficulties and nosebleeds, all of which could be caused by pollutants known to be emitted from gas sites. Similar problems have been reported by people who live in the Eagle Ford Shale in South Texas, the subject of a recent investigation by the Center for Public Integrity, InsideClimate News and The Weather Channel."
