Land fizzing like soda pop: farmer says CO2 injected underground is leaking

Winnipeg Free Press
"A Saskatchewan farm couple whose land lies over the world's largest carbon capture and storage project says greenhouse gases seeping from the soil are killing animals and sending groundwater foaming to the surface like shaken soda pop......Since 2000, Cenovus has injected about 16 million tonnes of carbon dioxide underground to force more oil from an aging field and safely store greenhouse gases that would otherwise contribute to climate change.

But in 2005, the Kerrs began noticing algae blooms, clots of foam and multicoloured scum in two ponds at the bottom of a gravel quarry on their land. Sometimes, the ponds bubbled. Small animals — cats, rabbits and goats — were regularly found dead a few metres away.

Then there were the explosions.

"At night we could hear this sort of bang like a cannon going off," said Jane Kerr, 58. "We'd go out and check the gravel pit and, in the walls, it (had) blown a hole in the side and there would be all this foaming coming out of this hole."
