(Salem, OR) -- Monsanto will pay Oregon 698-million dollars for decades of PCB contamination. PCBs were used in coolants, electrical equipment like transformers, fluorescent light bulbs, and hydraulic oils. PCBs accumulate in fish and wildlife and a lawsuit by the Oregon Attorney General alleged Monsanto knew since 1937 about the risks. PCBs stopped being produced in 1977. Money from the settlement will go toward cleanup PCB sites statewide.
