N.W.T. diamond mine reports spill of 450M litres of wastewater

The Diavik Diamond Mine in the Northwest Territories says 450 million litres of wastewater spilled due to a broken pipeline.

The spill took place on Feb. 7 but wasn't reported until late last week.

The Northwest Territories government says pipeline operators did not believe it needed to be reported as the wastewater leaked into a containment pond that was its final destination.

The government says its inspectors have confirmed the spill is within the pond and none has been released into the environment.
