Oilsands study confirms tailings found in groundwater, river

New federal research confirms that Albertas oilsands are polluting ground water and seeping into the Athabasca River.

The industry has maintained that toxic chemicals are contained safely in tailing ponds, but new research shows this isnt the case.

Well, it looks like what theyve seen is that in fact the tailings ponds are leaking, said Bill Donahue, environmental scientist with the oilsands advisory committee.

They found also not only are those tailings ponds leaking, but it looks like it is flowing pretty much from those tailings ponds, through the ground and into the Athabasca River.

So, there goes that message weve been hearing about. These tailings ponds are safe, they dont leak and so on."

Previous studies using models have estimated the leakage at 6.5million litres a day from a single pond.

But the Environment Canada study used new technology to actuallyfingerprint the mix of groundwater chemicals in the area.

It found the mix of chemicals from tailings is different fromthat in naturally occurring bitumen deposits.

That tailings mix, which contains toxic chemicals, is found ingroundwater around mining operations, but not in areas away fromdevelopment.

The Pembina Institute, an environmental research group, has long said the ponds leak. But analyst Erin Flanagan said the new research shows even Pembina underestimated how much.

"As we continue to expand the industry, we're also expanding the production of tailings waste."

The study, conducted under a new federal-provincial oilsands monitoring program, was accepted for publication in late January bythe journal Environmental Science and Technology.

The federal scientists were not available. The Alberta government says the research is of interest, but doesn't confirm anything.
