Explanation

PCBs (polychlorinated biphenyls) are toxic industrial chemicals used in electrical transformers and equipment before 1979, when their manufacture was banned. PCBs persist in the environment and can contaminate soil and groundwater near former industrial sites. Illinois has many former industrial properties that may have PCB contamination. Buyers of commercial properties should include PCB inquiry in their environmental due diligence.
