The aquifer's water quality is claimed to be at risk from leaks and spills from the Keystone XL tar sands pipeline by environmental organizations. In 2012, the Tar Sands Blockade mounted a campaign of peaceful and sustained civil disobedience justified by the groups claim that they are protecting the water quality of the aquifer by stopping the pipeline.
