Fracking will cause ‘irreversible harm’
Shale-gas extraction after-affects will threaten drinking water, could jeopardize agriculture, expert says

Marc Durand specializes in rock mechanics and hydrogeology. He gets it. Not only does he know that hydraulic fracturing will cause “irreversible harm” has says it will last for thousands of years. He also knows who will ultimately be stuck paying for the cleanup: the taxpayers. And, it won’t be cheap.
“The billions required would be much more than all the profits beckoning now,” said the retired Université du Québec à Montréal professor.
He says the shale wells will last about 8 years and only about 20% of the gas is recoverable, which is exactly in line with what we call the Shale Gas Shell Game.
As a hydrogeologist Durand understands that things are in static in the strata.
The rock formations shattered by fracking will be “thousands of times more permeable,” allowing the remaining 80 per cent of shale gas and underground water, 10 times more salty than sea water, to continue circulating, bubbling to the surface through the disused gas wells.
Over time, methane could leak into the groundwater and gas leaks could gush, uncontrolled, into the air.
“Because this happens deep below, it is not visible on the surface,” Durand wrote in a paper raising questions about shale gas.
