The Denver Radium site is a former radioactive mining site located in Denver, Denver County, Colorado. Industrial activities commenced at the site in 1886 with the construction of the Bailey Smelter. By 1903, the Colorado Zinc Company had constructed a mill on the site of the Bailey Smelter, and zinc milling operations continued until 1910. From 1914 to 1917, the U.S. Bureau of Mines operated a radium processing facility onsite, known as the National Radium Institute (NRI). Other onsite industrial activities included minerals recovery, manufacturing and servicing of storage batteries, treating and sacking of metallic ore insulation, oil reclamation, and landfilling. The ROD addresses approximately 16,500 cubic yards of metal-contaminated soil as OU9, the 9th of 11 OUs planned for the site. The primary contaminants of concern affecting the soil are metals, including arsenic, lead, and zinc.
