Radium
Radium is a chemical element with atomic number 88, represented by the symbol Ra. Radium is an almost pure-white alkaline earth metal, but it readily oxidizes on exposure to air, becoming black in color. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226,...

History

The site was opened in 1931 by the Lindsay Light and Chemical Company It processed ores like monazite
Monazite
Monazite is a reddish-brown phosphate mineral containing rare earth metals. It occurs usually in small isolated crystals. There are actually at least four different kinds of monazite, depending on relative elemental composition of the mineral:...

In 1967 AMPOT, and thus the facility, were bought by Kerr-McGee Corporation.

In around 1970, Kerr-McGee reorganized and AMPOT became the Kerr-McGee Chemical Corporation. The Rare Earths Facility was closed by Kerr-McGee in 1973.

In 2005 KMCC was spun off from Kerr-McGee as Tronox

, shortly before Kerr-McGee was bought by Anadarko Petroleum. Tronox inherited responsibility for the Rare Earths Facility and other sites. Tronox went bankrupt in 2009 and shareholders sued Anadarko Petroleum, partly for having misled investors in Tronox about its environmental debts.

Pollution

In the early years, people from the surrounding community used the mill tailings as fill dirt in various properties, such as their yards and gardens.. A woman who played in such a yard as a child later sued Kerr-McGee over her Hodgkin's disease and settled out of court in 1988.

Radioactive waste from the plant was put in a local landfill that later became a public park called Reed-Keppler Park.

Kress Creek and West Branch Dupage River (including sediments, banks, and floodplains) were contaminated by years of rainwater runoff from REF going into a storm sewer and then into the creek. The floodplain includes people's yards.

The West Chicago Sewage Treatment Plant was contaminated when mill tailings from REF were used as fill dirt there. This also resulted in pollution of the West Branch Dupage River from runoff
Surface runoff
Surface runoff is the water flow that occurs when soil is infiltrated to full capacity and excess water from rain, meltwater, or other sources flows over the land. This is a major component of the water cycle. Runoff that occurs on surfaces before reaching a channel is also called a nonpoint source...

Erosion
Erosion is when materials are removed from the surface and changed into something else. It only works by hydraulic actions and transport of solids in the natural environment, and leads to the deposition of these materials elsewhere...
