Lowry Landfill is located on 508 acres near the intersection of Quincy Avenue and Gun Club Road in Arapahoe County, just south and west of the Denver Arapahoe Disposal Site (DADS).

From the mid-1960s to 1980, the Lowry Landfill was operated as a regional landfill serving the Denver Metro area accepting both solid and industrial waste. In 1984, it was listed as a Superfund site due to the resulting groundwater contamination from industrial waste.

As the two lead parties, the City and County of Denver and Waste Management of Colorado have partnered to operate and maintain the remedy to ensure the community and environment are protected in the future. The process includes researching remediation options, designing, implementing, and operating a successful containment and treatment approach using the latest and most effective environmental technologies available.

A thriving and growing community surrounds the old Lowry Landfill and includes residential communities, businesses, schools, hiking trails, parks, shops, County Fairgrounds, and a golf course.

Home values in the area continue to increase, keeping pace with the surging home values throughout the Denver metro area.
