B.C. Minster of Energy and Mines Bill Bennett is expected to announce this morning the details of an investigation into the Mount Polley tailings pond failure.
On Friday, B.C. Environment Minister Mary Polak told CBC News there would be an independent inquiry into the accident.
Earlier this month, 10 million cubic metres of waste water plus more than four million cubic meters of sediment spilled into Hazeltine Creek after the dam at the mine's tailings pond failed.
Hundreds of people were ordered not to drink or bathe in their water after the dam burst two weeks ago.
Test results prompted the local health authority to later lift the water ban, but further test results released last week show that while the discharged sediment is still not toxic for humans, it may harm aquatic life.
The province says sediment samples collected Aug. 10 from the mouth of Hazeltine Creek and near Raft Creek in Quesnel Lake exceed guidelines and contaminated sites regulation standards for copper and iron.

These two images from the NASA Earth Observatory show the Mount Polley tailings dam on July 29, before the spill, and Aug. 5, the day after the spill.
"In the aftermath of the flood, a layer of brown sediment coated forests and stream valleys affected by the spill. Notice how much forest immediately north of the retention basin was levelled. Debris, mainly downed trees, are visible floating on Quesnel Lake," the website says.
(Editor's note: Some of the variations in colours between the two images are caused by different lighting conditions and viewing angles.)
