Coldwater Creek

Coldwater Creek is adjacent to several sites in the St. Louis, MO area which were involved in the processing and recovery of uranium during World War II. These sites were contaminated with radioactive waste as a result of the processing and recovery activities. While most of the radioactive wastes have been cleaned up, citizens have expressed concern that exposure to the wastes has increased the number of cancer cases in the area. As part of ongoing surveillance around some of these sites, and in response to community concerns, an analysis of cancer incidence in the area was completed using data from the Missouri Cancer Registry. Results of the analysis are posted below.

Weldon Spring

The Weldon Spring site is an area in St. Charles County about 30 miles west of St. Louis that was contaminated with hazardous radiological and chemical substances. The contamination stems from production of TNT and DNT by the U.S. Department of Army in the 1940’s and from enrichment of uranium ore and thorium processing by the Atomic Energy Commission in the 1950’s and 1960’s. The Department of Energy began clean-up efforts in 1980’s and most of the soils have been removed. The public has expressed concern about the hazardous effect of the sites on the public’s health, especially childhood leukemia. The Missouri Department of Health and Senior Services has reviewed the incidence and mortality of leukemia and the results are included in the below reports.
