After the long 2017 summer of watering bans and new revelations about perfluorochemicals in East Metro drinking water, the state of Minnesota and 3M Corp. finally settled the lawsuit for $850 million.

After legal fees and setting aside $40 million for immediate natural resources fixes, affected cities will share $720 million for improvements to water quality and sustainability, restoring the area's natural resources and miscellaneous statewide water or recreation projects. The last two will only be done if the first priority has been achieved, according to the order. To divvy up the funds, two working groups, including citizens, public officials, engineers and 3M representatives were formed to find the solutions.

DNR and MPCA representatives said in working group meetings they are hoping to start implementation of solutions by early 2020.
