In 2006, a 7,000 square foot water treatment facility was constructed at the Oakdale Public Works campus at 1900 Hadley Avenue. The facility resulted from action taken by the City and 3M to address and treat the presence of perfluorochemicals (PFCs) detected in the water supply. At the time, it was the first full scale treatment facility of its kind. The facility produces 2,400 gallons per minute of filtered water. Historical Information on Oakdale's Drinking Water.
Drinking Water Settlement
In early 2018, the state of Minnesota settled its lawsuit against the 3M Company in return for a settlement of $850 million. Minnesota’s attorney general sued 3M in 2010 alleging that the company’s production of chemicals known as PFCs had damaged drinking water and natural resources in the southeast Twin Cities metro area. After legal and other expenses are paid, about $720 million will be invested in drinking water and natural resource projects in the Twin Cities east metropolitan region.
