Field Investigation Of An Elevated Temperature Florida Landfill

Abstract

For reasons that are not entirely clear, incidents of elevated temperatures in landfills are occurring at increasing frequency in the US. A Florida landfill has experienced temperatures that well exceed the tolerable range for microorganisms and permit standards set by the Florida Department of Environmental Protection. The landfill has experienced elevated temperatures in gas wells on the west side of the active cell. These wells were installed in 2010 in an area that received biosolids treated with incinerator fly and bottom ash. These biosolids may have caused an exothermic reaction that has interrupted methane generation. In addition to elevated temperatures (as high as 175°F), smoke, odors, hydrogen in the landfill gas, leachate color darkening, and decreased leachate generation have been observed. However, abnormal settlement has not been observed in the landfill. Preliminary data analysis of gas temperatures suggests that 20% of the wells at the landfill are impacted. Waste samples have been collected and are being analyzed. Results of waste characterization support the presence of ash in areas of elevated temperature.
