Lab study cuts fracking waste’s radioactivity | The Sanford Herald

Lab study cuts fracking waste’s radioactivity | The Sanford Herald.

This is a curious find: flowback water mixed with “acid drainage from mining, or any other salty water” precipitates a good chunk of the radioactive material out of the water, thus binding it into a solid, more easily disposable form. I am not sure, in terms of isolating and removing radioactive materials, how much this differs from a standing practice of allowing the flowback water to sit in an open pit at the drill site and evaporate so the nasty material will be left behind.

What is encouraging is to see that after mixing the fluids, the research found that radioactive material was bound in solids, and the salinity of the water had diminished enough that it could be used again in fracking. That process saves some water supply while isolating materials to be handled as hazardous waste. Note that this is something that will be helpful in Pennsylvania and West Virginia, but not necessarily here in North Carolina since we do not have acid drainage from mining. {Ironically, it’s that acid wash that spilled in West Virginia causing 7 counties to be without public water supply, so this is still a nasty operation within a nasty operation.}

Also of note, since it was discussed today at the MEC meeting, the radioactivity of the disolved water in the flowback still has protection of the classified chemicals clause. We still don’t know what all is in the cocktail used in the slickwater fracturing process, but based on the discussion I heard in the meeting today (I was able to tune in to the middle portion, but not all of it: I would welcome more details on the meeting from those who were there or listened to the entire thing), the drilling operators would have to list on their permit request the chemicals to be used, and the state regulators would then acknowledge which are on the classified list. Regulators, as I understand it, would have to permit the site with appropriate chemical and wastewater storage, treatment, disposal, and spill response plan.

I am glad to see someone else in this article echo my feeling on the critical need for proper wastewater handling:

Tad Patzek, chairman and professor of the petroleum engineering
department at the University of Texas in Austin, cautioned that the
method could present problems in the field. The remaining water would
still be jam-packed with chemicals and toxins, he noted.

“That water can get spilled,” Patzek said. “That water can get into a shallow aquifer. There are many other considerations.”
