Is Fracking Fluid Safe To Drink?

Is fracking fluid (the water and chemical mixture that's injected underground at great pressure to break apart rock formations) safe to drink?  According to the Huffington Post, the folks at Halliburton think it is. I had to laugh, though - the Halliburton CEO didn't take a swig himself, but reportedly called another executive up to the podium to do the deed.

During a keynote lunch speech at the conference presented by the Colorado Oil and Gas Association, Halliburton Co. CEO Dave Lesar talked about addressing public concerns about hydraulic fracturing, which extracts natural gas by blasting a mix of water, chemicals and sand underground.

He raised a container of Halliburton's new fracking fluid made from materials sourced from the food industry, then called up a fellow executive to demonstrate how safe it was by drinking it, according to two attendees.
