Wolverine Worldwide has agreed to pay $69.5 million to local authorities and the state of Michigan over several years to remedy water contamination from chemicals used in a now-closed tannery and other company-owned facilities in the state. On the other hand, WWW will get $55 million in a lump sum from 3M as a settlement for the Scotchgard treatment used in the tanning process that caused the damage. The money paid to local authorities will help them to extend a municipal water system to serve 1,000 affected properties. WWW will continue to maintain water filters and resample some residential wells while adjusting its former tannery and other sites.
