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.
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.”
