$857 Million Verdict for Sky Valley School Victims Poisoned by Monsanto PCBs

Sky Valley Education Center in Monroe, Washington operated for years with fluorescent light fixtures that contained polychlorinated biphenyls (PCBs) manufactured by Monsanto. The ballasts in those fixtures leaked, releasing PCBs into the school's air. Students who attended the school and parents who volunteered there were exposed over months and years without knowing the chemicals were present.

Seven of those individuals became plaintiffs in a King County lawsuit against Pharmacia, the corporate successor to Monsanto's chemical manufacturing operations. Their injuries were severe. The group suffered brain damage, neurological dysfunction, lupus, autoimmune disorders, and other conditions they attributed to chronic PCB exposure. One plaintiff lost consciousness at the school. Others developed chemical sensitivities that required them to wear protective masks in daily life.

At trial, plaintiff attorneys including Henry Jones of Friedman Rubin presented scientific evidence that Monsanto had long known PCBs were toxic but continued manufacturing and selling them for use in building products. Experts testified that PCB exposure at the levels the plaintiffs experienced can cause precisely the kinds of neurological and immune injuries the group suffered.

On December 18, 2023, the jury returned a verdict totaling $857 million: $73 million in compensatory damages for the seven individuals and $784 million in punitive damages directed at Monsanto's corporate conduct. The punitive award worked out to roughly $112 million per plaintiff, reflecting the jury's assessment of how Monsanto had handled knowledge of its product's dangers, while the compensatory portion accounted for each plaintiff's specific harm.

The verdict was reported as the largest jury award in Washington State history at the time. It was also part of a broader wave of Sky Valley litigation: by late 2023, juries had collectively returned more than $1.7 billion in verdicts related to PCB exposure at the Monroe school, with additional trials pending. Bayer, which acquired Monsanto in 2018, said it planned to appeal and challenge the punitive damages as constitutionally excessive. A federal judge later reduced the total judgment to about $438 million, trimming the punitive award after finding the $784 million figure excessive, though the reduced amount still stands as one of the largest PCB-related awards tied to the Monroe school litigation.
