Time needed to gauge breach effects of broken tailings pond, says prof

"There's a cascading effect of concerns here," said Owens, who noted immediate questions regarding the amount of water, sediment and chemical introduced to Polley Lake, Hazeltine Creek and Quesnel Lake after the mine southeast of Quesnel suffered a rupture in its tailings pond dam Monday morning.
According to a statement by Energy and Mines Minister Bill Bennett, about 10 million cubic metres of water and 4.5 million cubic metres of sand were released, prompting the Cariboo Regional District to issue a precautionary ban on drinking or bathing in the water for the affected areas.
