Damage to Minnesota's public groundwater resources from construction of the Line 3 oil pipeline is more severe than previously known, state environmental regulators disclosed Monday.
Enbridge Energy crews ruptured three groundwater aquifers while building the 340-mile Line 3 replacement pipeline across northern Minnesota last year and the Canadian oil company faces expanded sanctions, the state Department of Natural Resources (DNR) said.
"The DNR continues to work on a comprehensive enforcement resolution, with the goal of addressing restoration, mitigation and additional penalties associated with the three breach locations," the agency said in a statement Monday announcing the completion of its investigation into the aquifer breaches.
