Fracking is vile
If they wish to play with locked in methane there is plenty of it in the sea.
Fresh water table ought to be free of playing with.
Fresh water tables are separated by thousands of feet of rock. Those cap rocks that kept the gas and oil contained in the first place keep the fracturing chemicals contained as well.
The fresh water table is 8-12,000 feet of impermeable rock, shale and chalk away from where the fracking is taking place.
In over fifty years of fracking history, no potable water source has ever been contaminated by the process.
