Oilsands tailings leaking into groundwater

How come there is little outcry about this? Oilsands tailings leaking into groundwater: http://www.edmontonjournal.com/business/oilsands+tailings+leaking+into+groundwater+oliver+told/7977885/story.html "Tailings ponds from oilsands production are leaking and contaminating Alberta’s groundwater, Natural Resources Minister Joe Oliver was told in an internal memo obtained by Postmedia News.
The memo, released through access to information legislation, said that federal government scientists, including Quebec City-based research geoscientist Martine Savard, had discovered evidence of the contamination in new research that rejected longstanding claims that toxins in the region of the Athabasca River were coming from natural sources.
“The studies have, for the first time, detected potentially harmful, mining-related organic acid contaminants in the groundwater outside a long-established out-of-pit tailings pond,” said the memo from deputy minister Serge Dupont, dated June 19, 2012."
