Oil giant Exxon Mobil Corporation (NYSE: XOM ) is being sued for $5 million after one of its pipelines burst which led to a small oil spill in an Arkansas town. The Exxon Mobil Corporation (NYSE:XOM) pipeline, Pegasus, was carrying Canadian crude oil from Illinois to the refinery hub of the Gulf of Mexico. While the cause of the spill is still under investigation, it's not believed to have had any major impact on the drinking water supply, though it still caused damage to a handful of houses. Two of those homeowners are now filing suit saying that the rupture has caused permanent damage to area property values.
