Potential Exposure at Fort McClellan
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.
Although exposures to high levels of these compounds have been shown to cause a variety of adverse health effects in humans and laboratory animals, there is no evidence of exposures of this magnitude having occurred at Fort McClellan.

PCBs and the Monsanto chemical plant

From 1929 to 1971, an off-post Monsanto chemical plant operated south of Fort McClellan in Anniston. PCBs from the plant entered into the environment, and the surrounding community was exposed.
In 2013, the Agency for Toxic Substances and Disease Registry (ATSDR) completed an assessment of the potential health risks caused by airborne PCBs in Anniston and concluded that the concentrations found were "not expected to result in an increased cancer risk or other harmful health effects in people living in the neighborhoods outside the perimeter of the former PCB manufacturing facility."
