Proper operation is essential to minimize impacts on local air quality and water resources.

In the semi-arid climate of eastern Colorado, groundwater protection is a key concern for landfills. Leachate management systems must prevent contamination of shallow aquifers. Landfill gas, primarily methane, requires collection and flaring or energy recovery to reduce greenhouse gas emissions. The rural setting means lower community proximity risks, but traffic and odor management remain important for local residents.
