Cornell Study Links Fracking Wastewater with Mortality in Farm Animals by John Messeder

It has been a rough week for the shale industry. Earthquakes have been tied to a deep wastewater injection well and resulted in, among other things, demonstrations on the lawn of the Ohio Statehouse. And residents in rural central New York are organizing door-to-door petition drives to halt hydraulic fracturing —if not in their state, at least in Madison and Oneida Counties.

A recently completed study by two Cornell University researchers indicates the process of hydraulic fracturing deep shale to release natural gas may be linked to shortened lifespan and reduced or mutated reproduction in cattle—and maybe humans.

Fracking (the colloquial name for hydraulic fracturing), involves drilling a well about 8,000 feet down, and then up to about 13,000 feet horizontally. Three to five million gallons of fresh water, specially formulated sand and up to 250,000 gallons of chemicals, some of them highly toxic, are poured into the well at great pressure, breaking the deep shale and releasing the coveted gas.

Without knowing exactly what chemicals are being used, and in what quantities, it is difficult to perform laboratory-style experiments on, say lab rats. But farm animals are captive, surrounded by electric and barbed wire fences.

And when fracking wastewater is spilled across their pasture and into their drinking water, and they start dying and birthing dead calves, one can become suspicious that there is a connection.

Which is what the Cornell researchers found during a year-long study of farm animals, based primarily on interviews with animal owners and veterinarians in six states: Colorado, Louisiana, New York, Ohio, Pennsylvania and Texas.

“Animals can nevertheless serve as sentinels for human health impacts,” the report, titled Impacts of Gas Drilling on Human and Animal Health, notes. “Animals, particularly livestock, remain in a confined area and, in some cases, are continually exposed to an environmental threat.”

The report has been produced by Robert E. Oswald, a biochemist and Professor of Molecular Medicine at Cornell University, and Michelle Bamberger, a veterinarian with a master’s degree in pharmacology.

In one case, an accidental release of fracking fluids into a pasture adjacent to a drilling operation resulted in 17 cows dead within an hour. Exposure to fracking fluids running onto pastures or into streams or wells also reportedly led to pregnant cows producing stillborn calves, goats exhibiting reproductive problems and other farm animals displaying similar problems. Farmers reported effects within one to three days of animals consuming errant fracking wastewater.
