Atomic Fallout

The Missouri Independent, MuckRock and The Associated Press spent months combing through thousands of pages of previously-unreleased government records obtained through the Freedom of Information Act that show radioactive waste was known to pose a threat to people living near Coldwater Creek as early as 1949. But federal officials repeatedly wrote potential risks off as ‘slight,’ ‘minimal’ or ‘low-level.’ Newly released records, however, reveal how the government downplayed and ignored health risks of St. Louis radioactive waste for decades, with severe consequences.

Over six months, more than two dozen journalists and researchers pored over 6,700 pages of federal government documents, many of which had been either newly-declassified or never before reviewed.

We consulted experts to analyze the reports anew, to see if the environmental and radioactivity testing done decades ago could be seen and understood in a different, modern light.

The result is “Atomic Fallout,” a sweeping historical investigation. In addition to the full report, you can explore the the history of the St. Louis nuclear waste site in an interactive map and read some of the key findings of our joint report. If you’re a journalist interested in applying our lessons to your own reporting project, or just want to know more about the process, there’s also a guide to how our ‘Atomic Fallout’ reporting came together.
