AJO MSW LANDFILL - Municipal Solid Waste Landfill in Ajo, Arizona

AJO MSW LANDFILL is an operational municipal solid waste landfill located 1.4 miles north of AZ 85 in Ajo, Arizona. Serving Pima County, this facility plays a key role in regional waste management for the surrounding community. As a Subtitle D landfill, it operates under the US EPA's Resource Conservation and Recovery Act (RCRA) regulations, which govern design, operation, and closure standards. The facility likely includes liner systems, leachate collection, and groundwater monitoring to comply with federal and state requirements. Arizona's arid climate reduces leachate generation but necessitates dust control and methane management. The landfill's location in a rural desert area minimizes community proximity concerns but requires careful management of landfill gas and groundwater impacts. Its operational status ensures continued service for Ajo and nearby areas, supporting local public health and environmental protection.

The Ajo area's arid desert climate reduces rainfall, limiting leachate production but increasing dust and odor management challenges. Groundwater protection is critical due to the region's reliance on aquifers. Landfill gas, primarily methane, must be collected or flared to mitigate greenhouse gas emissions and comply with Clean Air Act regulations. The facility's rural setting reduces traffic and noise impacts on communities.
