When the ExxonMobil Pegasus pipeline split open in late March it spilled 210,000 gallons of oil into a small Arkansas town. The spill galvanized opponents of the Keystone XL Pipeline, who cited its planned path through major rivers and aquifers. Activists say TransCanada, which would build and operate the pipeline, underestimate the size of potential spills.
"I don't agree with people who say a spill into the aquifer will ruin the whole aquifer. It would ruin a very small piece, but it's important if that's your small piece," John Stansbury, a University of Nebraska professor of environmental and water resources engineering. "But if it got into a major river, it could create a plume hundreds of miles long."

Residents of Mayflower, Ark., spent Easter weekend evacuated from their homes as Exxon Mobil attended to a major oil spill from a crude oil pipeline. Residents described scenes of oil running down the streets like a river, as 22 families were forced to leave their homes.
Since the pipe burst on Friday afternoon, cleanup crews have collected around 12,000 barrels of oil and water. Images from the weekend show quiet cul-de-sacs inundated with thick, black sludge, and parents reported concern for their children and whether they would be able to play outside.
