The Southwest Regional Landfill is situated in the Sonoran Desert region of Arizona, where arid conditions reduce rainfall but increase the potential for dust and air quality concerns. Landfill gas management, including methane capture, is critical to mitigate greenhouse gas emissions. Leachate generation is lower due to low precipitation, but groundwater protection remains important given the proximity to the Gila River watershed. Community proximity and truck traffic are factors in the Buckeye area, which has seen population growth.
