Rusty barrel being lifted out of Lake SuperiorThe Minnesota Pollution Control Agency worked in cooperation with the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers to locate and recover barrels dumped by Honeywell Corp. (Minneapolis) into Lake Superior in the 1960s.

The MPCA has completed its investigation of the Lake Superior barrels. Based on current data and information, the MPCA does not believe that the barrels present a threat to human health or the environment. All the information regarding the MPCA five-year investigation of the Lake Superior barrels is public and staff will continue to provide access to this information. The MPCA is also willing to cooperate with any new investigations by the federal government, local government, Tribal Governments, or others. However, there are currently no additional funds to contribute to further investigations. If any future investigations provide evidence of a threat to human health or the environment from these barrels, the MPCA would then consider the need for additional funding.
