Emergency personnel from fire departments including Cortland, DeKalb, Sycamore, Maple Park-Countryside, Elburn, Burlington, Hinckley, Rochelle and Genoa-Kingston are seen outside Cortland Elementary School in Cortland, Ill., on Tuesday, Jan. 14, 2014. Gas released from the nearby landfill got caught in the school's ventilation system making staff and students nauseous.
