denver radium site

VARIOUS PLACES IN DENVER

The Denver Radium site, located in Denver, Colorado, consists of over 65 properties along the South Platte River Valley. These properties were contaminated by radioactive residues derived from the processing of radium in the early 1900s. The site was added to the Superfund National Priorities List (NPL) in September 1983. The properties were divided into eleven operable units (OUs), based on their location, to simplify the cleanup process. EPA published a Federal Register notice on September 9, 2010, partially deleting from the NPL each of the 11 OUs at the Denver Radium site. Groundwater contamination associated with OU8 will remain on the NPL.
