A waste management employee uses a tarp to cover the active landfill site at Waste Management in Cortland, Ill., on Monday April 5, 2010. The daily act of covering the active site with plastic and soil is meant to keep garbage and odors  contained as well as keep disease carrying rodents and birds from penetrating the landfill.
