The tailings ponds storing waste water left over from the processing of Alberta tar sands oil are leaking an estimated 11 million litres of contaminated water every day, according to a new report.
The figure, one of the first publicly available on the scale of the seepage from tailing ponds that dot the landscape in Northern Alberta, is being released today in a report by Environmental Defence, a Toronto-based conservation advocacy group.
