FLORISSANT, Mo. (AP) — A Missouri school board has decided to shut down a grade school that sits near a contaminated creek after a study funded by law firms involved in a class-action lawsuit found high levels of radioactive material inside the school. Contamination was found in classrooms, the playground and elsewhere at Jana Elementary School in Florissant, Missouri, according to a report last week by Boston Chemical Data Corp. It follows another study by the U.S. Army Corps of Engineers, made public in the summer, that found contamination stemming from World War II-era nuclear weapons production in a wooded area near Coldwater Creek.
