Methane Investigation at Central Illinois Landfill

Keith Hackley completed an investigation of a landfill in central Illinois to determine the origin of the methane detected in some of the monitoring gas probes on site. Isotopic analyses indicated that three sources of methane were detected: natural drift gas, gas produced from recent burial of natural debris during construction at the site, and landfill gas migrating from the refuse facility itself. Such information will help the landfill owners determine how to remediate the methane.
