Sen. Josh Hawley (R-Mo.) and Rep. Cori Bush (D-Mo.) last week called for prompt federal action after a Boston Chemical Data report by environmental scientist Marco Kaltofen claimed that radioactive contamination near the Coldwater Creek Superfund Site in St. Louis County was more serious than previously thought. The Hazelwood, Mo., Board of Education last week stopped using the building and sent students home for remote learning at least temporarily for most students. "We continue to conduct testing along Coldwater Creek, to address community safety concerns about the findings, using proven collection and laboratory methods to ensure any contaminated materials found to exceed the cleanup standard is addressed," the Corps spokesperson said via email. The Corps is also currently considering the best format and location for a public briefing on the safety of the school, the spokesperson said.
