Fracking Will Cause 'Irreversible Harm': Shale-Gas Extraction After-Affects Will Threaten Drinking Water, Could Jeopardize Agriculture, Expert Says--Montreal Gazette

QUEBEC - A geological engineering professor whose specialty is rock mechanics and hydrogeology says hydraulic fracturing to free natural gas from shale rock formations will cause "irreversible harm" lasting thousands of years.

And the gas companies will be long gone, leaving behind costly remediation, Marc Durand said in an interview, suggesting the gas producers should be forced to establish a reserve fund.

"The billions required would be much more than all the profits beckoning now," said the retired Université du Québec à Montréal professor.

The circulating gas left behind will threaten the water Quebecers drink and could jeopardize agriculture, he said. The Utica shale field gas deposits between Montreal and Quebec City lie under some of the best farmland in the province.

"Fracking" is the technique of pumping a mixture of water, sand and a cocktail of toxic chemicals under pressure into wells drilled horizontally to liberate the gas from the shale.....continued.....
