Michigan AG secures $108 million Monsanto settlement over PCB contamination

Michigan Attorney General Dana Nessel announced a $108 million settlement with Monsanto, Solutia and Pharmacia over PCB contamination, marking a major funding source for cleanup and restoration efforts in the state.

The announcement came on May 18, 2026. Michigan said the money will support remediation and restoration work tied to harms from polychlorinated biphenyls, or PCBs, with oversight from the Michigan Department of Environment, Great Lakes, and Energy and the Department of Natural Resources.

PCBs were widely used in industrial products before being banned in the United States because of health and environmental concerns. In Michigan, state officials said the settlement is meant to help address contamination impacts and support recovery in affected areas.

Reuters reported that Bayer's Monsanto unit will pay at least $133 million across Michigan and Rhode Island combined. Rhode Island separately announced a $25 million PCB settlement the same day, with the potential to rise to $62.5 million under that state's agreement.

The Michigan settlement adds to broader state efforts to recover costs connected to PCB contamination and to fund environmental restoration. The deal is part of continuing litigation activity involving Monsanto and related entities over the legacy pollution.

Further details on how and when the funds will be distributed were not immediately clear.
