Tar Sands Tailings Contaminate Alberta Groundwater

It’s just one of those ho-hum ecocides. It could only be met with indifference by a Canada ruled by the shameful Harper government, focused on ‘Canada’s Economic Action Plan.’

The massive tailings ponds holding billions of litres of tar sands waste are leaking into Alberta’s groundwater, according to internal documents obtained by Postmedia‘s Mike De Souza.

An internal memorandum prepared for Natural Resources Minister Joe Oliver and obtained through Access to Information legislation says evidence confirms groundwater toxins related to bitumen mining and upgrading are migrating from tailings ponds and are not naturally occurring as government and industry have previously stated.

“The studies have, for the first time, detected potentially harmful, mining-related organic acid contaminants in groundwater outside a long-established out-of-pit tailings pond,” the memo reads. “This finding is consistent with publicly available technical reports of seepage (both projected in theory, and detected in practice).”

This newly released document shows the federal government has been aware of the problem since June 2012 without publicly addressing the information. The study, made available online by Natural Resources Canada in December 2012, was still “pending release” at the time Minister Oliver was briefed of its contents in June.

The study in question, co-authored by 19 scientists from both provincial and federal bodies including Natural Resources Canada, Environment Canada, the Geological Survey of Canada, was designed to distinguish naturally-occurring chemical substances from mining-related contaminants.

Canadian Association of Petroleum Producers (CAPP) spokesman Travis Davies told Postmedia’s De Souza the study’s evidence of chemical seepage into groundwater did not come as a surprise.

“Their study isn’t new in any way other than perhaps the laboratory methods and detection limits,” Davies said. “We also know and report on the chemistry of groundwater from our monitoring wells that surround tailings facilities. So again, (there’s) no surprise.”

CAPP’s website had recently been updated to acknowledge(s) “seepage into ground water can occur,” although still claims “comprehensive monitoring programs have not detected impacts from tailings ponds seepage on surface water or to ground water.” MORE
