Is there a health hazard from exposure to landfill gas to local residents?
As stated in previous sections of the health assessment, a gas extraction system utilizing 91 gas extraction wells has been installed at the site. The gas is used as a fuel source in a sludge drying operation. During combustion of the gas, contaminants are also burned. The gas extraction system has minimized present and future exposures to local residents. • Is leachate escaping from the site? Is it flowing into Killbuck Creek? During construction of the landfill, a leachate collection system was installed. The floor of the landfill was graded to drain to various manholes placed throughout the landfill. Leachate is removed by a series of eight submersible pumps that are moved to service the manholes existing in the landfill. Leachate is also periodically pumped out of the gas extraction wells. In 1992, a sanitary sewer line was installed which connects the WRL site to the Rock River Water Reclamation District, a local publicly owned treatment works (POTW). Since then, leachate has been
