Lemons East Sanitary Landfill and Lemons West Landfill - Dexter, Missouri Solid Waste Management

Lemons East Sanitary Landfill and Lemons West Landfill are two adjacent landfill facilities located in Dexter, Stoddard County, Missouri, United States. Operated by Republic Services, Inc., these landfills have been in operation since 1979 and are projected to remain open until 2048. They are classified as municipal solid waste landfills, handling waste from the surrounding communities and industries. As landfills in the United States, these facilities operate under the regulatory framework of the Environmental Protection Agency (EPA), specifically RCRA Subtitle D for municipal solid waste landfills and Clean Air Act (CAA) regulations for landfill gas management. The landfills are subject to requirements for liner systems, leachate collection, groundwater monitoring, and gas collection and control. The long operational history and projected lifespan indicate a significant waste management role in the region. The environmental significance of these landfills lies in their management of landfill gas and leachate. Landfill gas, primarily methane, is a potent greenhouse gas, and proper collection systems are critical to mitigate emissions. Leachate management is essential to protect groundwater quality, especially given the proximity to agricultural areas and the Mississippi River basin. The facilities' location in a rural county also involves considerations of community proximity and traffic impacts from waste hauling operations.

The landfills are situated in Stoddard County, Missouri, a rural area with agricultural land and proximity to the Mississippi River. The local environmental context includes potential risks to groundwater from leachate, as the region's hydrogeology may facilitate contaminant transport. Landfill gas emissions, particularly methane, contribute to greenhouse gas concentrations, and effective gas collection systems are necessary to reduce atmospheric impact. Community proximity and increased traffic from waste hauling are additional environmental considerations for this facility.
