A jury in Baltimore County has ordered Exxon Mobil Corp (NYSE:XOM) to pay $495 million in compensatory damages related to a gas station leak in 2006, the Baltimore Sun reported today.That amount doesn’t include the punitive awards for 160 affected businesses and families, which could total over $2.5 billion, after a lawyer for the group asked the six-member civil jury to consider a punitive damage award of three to five times the compensatory damages.The 2006 leak spilled about 26,000 gallons of gasoline into the groundwater in Jacksonville, Florida, which has no public water or sewer service and depends on private wells for drinking water.Exxon's lawyers said the company has spent $46 million on cleanup.Shares of Exxon Mobil are trading up 0.8% at $80.89.
