Lowry Landfill

The Lowry Landfill is a 507-acre Superfund site located two miles east of Aurora, Colorado on a former federal bombing range and former Titan missile facility. Between 1965 and 1980, the city and county of Denver oversaw the dumping of 138 million gallons of industrial and municipal waste into the landfill. Legally disposed waste products included industrial chemicals, paint, pesticides, medical and veterinary waste, petroleum products, sewage sludge, tires, and household waste. Through its years of use, the Lowry Landfill is responsible for contaminating soil, groundwater, surface water, and sediment with hazardous chemicals. Air spaces were also contaminated, due to gases produced by buried waste. Remediation began in the mid-1980s and is ongoing, supervised by the state of Colorado and the Environmental Protection Agency (EPA). Water is being treated and used to irrigate public lands throughout Denver. Operation and maintenance activities continue.

Rumors of illegal dumping of radioactive waste from the Rocky Flats plant at the Lowry Landfill have circulated for years. A series of investigative reports published in the early 1990s argued that illegal dumping of plutonium occurred from the 1950s to about the 1980s. The “Lowry Coalition”—a group of companies implicated in the Superfund case—released a report in 1991 showing elevated levels of americium and other transuranic elements at the site. Although subsequent testing showed no transuranics above background level and the EPA believes the first findings to be in error, some citizen groups remain convinced that the cleanup process enabled a cover-up of the extent of radioactive contamination, citing corporate ties between the polluters, the media, and the remediation contractors at Rocky Flats and Lowry.
