If you don't understand that hydraulic fracturing can result in waste that's disposed of by injection, then you don't understand it.
There once again you display ignorance on oil and gas operations.
Hydraulic fracturing uses fluids including water, some of which is produced back. Of that which is produced back, a lot of it, as I have already shown you, is re-used in other frac operations.
I really do not know what else to tell somebody that refuses to understand what fraccing and water disposal really are.
