Toxic chemicals known as polychlorinated biphenyls, or PCBs, were used in construction materials and other applications in thousands of schools nationwide from the 1950s until their manufacture was banned by the EPA in 1979. Their presence has been linked to a wide range of short- and long-term health concerns, and sparked hundreds of liability lawsuits. Joyce Marquardt taught in a school in Washington state contaminated with PCBs. She became sick and was one of three teachers who received a settlement from her district and a $185 million jury award for damages from PCB manufacturer Monsanto. The company is appealing that verdict and argues that the school districs and other parties should bear responsibility. This is Marquardt鈥檚 story.
