Results indicate that there are no current risks to students or residents
The U.S. Environmental Protection Agency (EPA) has completed its review of soil data, following the sampling that took place at the Davis R-12 school in Henry County, Missouri, on June 23, 2025.
The results of EPA’s sampling indicate that levels of hexavalent chromium are well below EPA’s action levels, which are used by EPA to determine when a soil removal would be appropriate for a residential yard. The highest level of hexavalent chromium detected was 70 times below the action level. Action levels are set with a significant safety factor.
“EPA Region 7 worked quickly with the Davis R-12 School District and Henry County to produce these results. I am happy to report that these results do not exceed our action levels,” said EPA Region 7 Administrator Jim Macy. “We follow a rigorous scientific process at EPA, and Henry County residents should have a high level of confidence in these results showing that they are not at risk from hexavalent chromium.”
Similarly, levels of arsenic, cobalt, and lead did not exceed EPA’s action levels. These metals were within normal background levels found in the Sunbelt Environmental report prepared for Henry County Emergency Management. This means that the levels of these contaminants detected in soil samples fall within a naturally occurring range for these constituents in this area of Missouri.
EPA Region 7 has shared this data with Davis R-12 leadership and Henry County officials.
These results are also available on the EPA webpage for Henry County, Missouri.
