The problem is there's no definition of what's technically safe, what's technically unsafe, and few, if any guidelines defining acceptable fracking procedures.

The problem is there's no definition of what's technically safe, what's technically unsafe, and few, if any guidelines defining acceptable fracking procedures. What goes into the ground? A proprietary mix of who knows what, and you can't find out because they won't tell you. It's a trade secret. Where does that stuff go? Again, few if any simulations have been run on the long-term consequences of injecting this stuff into the ground. It's not that fracking should be banned, it's that it should be understood.
