Beginning in 1962, portions of the property were used for landfilling of municipal solid waste and construction debris.
Two areas became radiologically contaminated in 1973 when soils mixed with uranium-ore-processing residues were used as daily cover in the landfilling operation.
An adjacent property has also been impacted by erosional migration of radiologically-contaminated material from the landfill proper.
This property, known as The Buffer Zone or The Crossroad Property, was subsequently purchased by the landfill operator. It is considered part of the site and is enclosed within the site’s perimeter security fence.
Also located on the site is the Bridgeton sanitary landfill, which ceased operation in 2005. This sanitary landfill did not receive any of the radiologically contaminated soil.
