I doubt that, but they'll probably ban the use of benzene, and any waste fluids that gov't waste water treatment plants can't handle unless the drilling companies want to clean it completely up to gov't specifications in the Clean Water Act.
A lot of frac fluids which cannot be cleaned and re-used are disposed the same way as production water—in disposal wells. That is another practice that has been in use for over 60 years. Only real slobs or screw-ups would dump the water where it will cause problems, and the States can pull their permits and shut them down.
Are you saying that benzene is one of the injection fluids. Sure wouldn’t want that leaking into my aquifer.
