Denver Arapahoe Disposal Site (DADS) - Landfill in Aurora, Colorado

Denver Arapahoe Disposal Site (DADS) is a major landfill facility located at 3500 South Gun Club Road in Aurora, Arapahoe County, Colorado. Owned by the City and County of Denver and operated by WM, this site has been serving the region's solid waste management needs since 1966. With a projected closure year of 2154, it represents a long-term waste disposal solution for the Denver metropolitan area. As a large-scale landfill, DADS operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste and Clean Air Act requirements for landfill gas management. The facility is subject to Colorado state regulations and local ordinances governing waste disposal, leachate management, and methane emissions. Landfills of this scale typically employ gas collection systems to mitigate methane leakage and may generate electricity from captured landfill gas. The environmental significance of DADS lies in its role as a primary waste disposal site for a major urban area. Proper management of landfill gas and leachate is critical to minimize groundwater contamination and air emissions. The facility's long operational lifespan underscores the importance of sustainable waste management practices and regulatory compliance to protect nearby communities and ecosystems.

The Denver Arapahoe Disposal Site is situated in the semi-arid climate of Colorado's Front Range, where groundwater resources are vital. Landfill operations must carefully manage leachate to prevent contamination of the underlying aquifer. Methane emissions from decomposing waste are a key environmental concern, and the facility likely employs gas collection systems to reduce greenhouse gas emissions. Proximity to residential areas in Aurora necessitates rigorous odor and traffic management to minimize community impact.
