After Over a Decade of Fracking, Oversight of Industry's Radioactive Waste Still Lacking

It has been roughly twelve years since fracking launched the great shale rush in the U.S. and the biggest problem with the technology — how to safely dispose of the enormous quantities of toxic waste generated — remains unsolved.

In particular, regulators have struggled to fully understand or police the hazards posed by radioactivity found in fracking waste.

The most common form of radioactivity in shale waste comes from radium-226, which happens also to be an isotope that takes the longest to decay. To be exact, radium-226’s half-life of roughly 1,600 years means that well over a millennium and a half from now, more than half of the radium that fracking brings to the surface today will still be emitting dangerous radioactive particles.

Concern about the waste has taken on renewed urgency in light of a detailed report published in Environmental Health Perspectives (EHP), a peer-reviewed scientific journal which is backed by the National Institutes of Health. The study concluded that worrisome and extensive gaps in federal and state oversight of this radioactivity problem still persist.

At the federal level, radioactive oil and gas waste is exempt from nearly all the regulatory processes the general public might expect would govern it,” the researchers wrote. “State laws are a patchwork.’”

This is not an entirely new finding. Several years ago, a New York Times investigative piece highlighted how the oil and gas industry routinely dumped radium-laced waste water into rivers. State regulators in Pennsylvania and the oil and gas industry adamantly denied there was a problem.

So what's changed? The recent academic study concludes that even several years later, worrisome oversight lapses remain. As such, the researchers wrote, there is continuing reason for concern.

We are troubled by people drinking water that [could potentially have] radium-226 in it,” David Brown, a public health toxicologist with the Southwest Pennsylvania Environmental Health Project, told the researchers (insert in original). “When somebody calls us and says ‘is it safe to drink our water,’ the answer is ‘I don’t know.’”

Coast Guard Proposal to Allow Barges to Haul Fracking Wastewater Draws Fire From Environmentalists

The U.S. Coast Guard released plans that would allow wastewater from shale gas to be shipped via barge in the nation’s rivers and waterways on October 30 — and those rules have kicked up a storm of controversy. The proposal is drawing fire from locals and environmentalists along the Ohio and Mississippi rivers who say the Coast Guard failed to examine the environmental impacts of a spill and is only giving the public 30 days to comment on the plan.

Three million people get their water from the Ohio River, and further downstream, millions more rely on drinking water from the Mississippi. If the Coast Guard's proposed policy is approved, barges carrying 10,000 barrels of fracking wastewater would float downstream from northern Appalachia to Ohio, Texas and Louisiana.

Environmentalists say a spill could be disastrous, because the wastewater would contaminate drinking water and the complicated brew of contaminants in fracking waste, which include corrosive salts and radioactive materials, would be nearly impossible to clean up.

The billions of gallons of wastewater from fracking represent one of the biggest bottlenecks for the shale gas industry.

States atop the Marcellus shale are brimming with the stuff. Traditionally, oil and gas wastewater is disposed by pumping it underground using wastewater disposal wells, but the underground geology of northeastern states like Pennsylvania makes this far more difficult than in states like Texas, and Ohio has suffered a spate of earthquakes that federal researchers concluded were linked to these wastewater wells. The volumes of water used by drillers for the current shale gas boom are unprecedented.
