Up to 1,000 gallons of water used in mining operations reached a creek and tundra, as an estimated 400,000 gallons spilled into containment areas and a gravel road.

The EPA settled with Red Dog Mine for failing to identify hazardous waste for over four years, marking the mine's largest violation in its 30-year operation.

The Red Dog Mine announced last week that it was able to start the use of a new waste water treatment system to purify water after record-breaking warm weather in 2019 caused the sediment levels to rise in the Ikalukrok and Wulik Rivers.

Permafrost thaw surrounding the massive Red Dog Mine is releasing higher natural levels of dissolved minerals and other particles into streams, Teck Resources Ltd. says

The multinational company that operates the Red Dog Mine in Northwest Alaska says that thawing permafrost linked to global warming has forced it to spend nearly $20 million to manage its water storage and discharge.
