Wisconsin Company Tasked to Remove ‘Stamp Sands’ Threatening Fish Species in Lake Superior

A Wisconsin-based company will be tasked to remove copper mine waste from the Grand Traverse Harbor in Lake Superior.

The company was given the contract in order to remove hazardous “stamp sands” from in and around the harbor.

The waste threatens to damage crucial fish spawning habitats more than a century after companies dumped it into the water.

They will also remove waste from the riverbed area north of Buffalo Reef.

Officials say this will buy time to develop a long-term plan that will help deal with the stamp sands that endanger the reef.
