South Yuma County Landfill - Yuma, Arizona Solid Waste Management Facility

South Yuma County Landfill is an operational solid waste management facility located in Yuma, Arizona, United States. Owned by CR&R, Inc., the landfill has been serving the region since 2001 and is projected to remain open until 2080. It is classified as a landfill facility, providing essential waste disposal services to the Yuma area. The landfill operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste and Clean Air Act regulations for landfill gas management. As a landfill in Arizona, it must comply with state and federal standards for leachate control, groundwater monitoring, and methane gas collection. The facility's long operational timeline suggests significant capacity and ongoing management of environmental controls. Environmental considerations for South Yuma County Landfill include landfill gas generation and methane leakage, leachate management to protect groundwater, and community impacts such as traffic and odor. The facility's location in a desert region may influence groundwater recharge and gas migration patterns. Proper operation is critical to minimize environmental risks and ensure compliance with regulatory standards.

The Yuma area is characterized by an arid climate with low rainfall, which reduces leachate generation but increases dust and odor concerns. Groundwater resources in the region are limited and sensitive to contamination, making leachate management crucial. Landfill gas collection systems are typically required to mitigate methane emissions, a potent greenhouse gas. Community proximity and traffic from waste hauling are additional environmental factors that require careful management.
