Fort McClellan was an Army installation in Alabama that opened in 1917.
Some members of the U.S. Army Chemical Corp School, Army Combat Development Command Chemical/Biological/Radiological Agency, Army Military Police School and Women's Army Corps, among others, may have been exposed to one or more of several hazardous materials, likely at low levels, during their service at Fort McClellan. Potential exposures could have included, but are not limited to, the following:
- Radioactive compounds (cesium-137 and cobalt-60) used in decontamination training activities in isolated locations on base.
- Chemical warfare agents (mustard gas and nerve agents) used in decontamination testing activities in isolated locations on base.
- Airborne polychlorinated biphenyls (PCBs) from the Monsanto plant in the neighboring town.
