An oil pipeline spill in Arkansas could keep some people out of their homes for weeks.
Exxon Mobil said more than 12,000 barrels of oil and water have been recovered since the pipeline ruptured Friday.
"We've just gotten used to having pipelines go through cities and counties, and you hope something like this doesn't happen," Allen Dodson, a Faulkner County judge who is the top executive for the county where the spill occurred, told Reuters. "My heart goes out to all of the people personally impacted."
The spill could play a role in the politics surrounding the Keystone XL Pipeline project. Environmentalists have criticized that proposal, saying a pipeline could be prone to spills.
"Whether it's the proposed Keystone XL pipeline, or ... [the] mess in Arkansas, Americans are realizing that transporting large amounts of this corrosive and polluting fuel is a bad deal for American taxpayers and for our environment," Reuters quoted Rep. Ed Markey, D-Mass.
But the government says pipelines release less pollution than shipping oil by rail.
