Oil giant ExxonMobil faces mounting criticism of its clean-up efforts after one of its oil pipelines ruptured on Friday and leaked 42,000 gallons of crude oil into Montana’s Yellowstone River. The company initially downplayed the incident by saying it would only effect 10 miles of the river but state officials say the oil has already stretched over 240 miles to near the North Dakota border. The spill comes as the Obama administration considers a massive new oil pipeline called the Keystone XL that would carry corrosive tar sands oil from Alberta, Canada to the Gulf of Mexico. The pipeline would cross the Yellowstone River as well as the Ogallala aquifer — the largest fresh-water aquifer in the U.S. We speak with Alexis Bonogofsky, a family farmer who lives along the Yellowstone River and was briefly hospitalized after suffering from what doctors diagnosed as acute hydrocarbon exposure.
