As long as oil companies have been operating in Fort McMurray, Alberta, tailings ponds have been a problem. Now, a new report released by Environmental Defence indicates that each day 11 million litres of contaminated water are leaking from tar sands operations into surrounding areas. Although this already is a disturbing figure, planned expansion of tar sands operations means that it is expected to grow to over 72 million litres per day within a decade. (Seventy-two million litres would fill Toronto's Rogers Centre 16 times.) The water, known to contain dozens of toxic contaminants such as heavy metals, polycyclic aromatic hydrocarbons and naphthenic acids, enters the groundwater and the Athabasca River before the river flows into Fort Chipewyan and the Peace Athabasca Delta, one of the world's largest inland freshwater deltas.
