(Portland, OR)  --  Portland City Attorney Tracy Reeve now has authorization to sue the Monsanto Company.  The city council passed a resolution to authorize the lawsuit, which would seek damages for contamination of Portland's waterways with cancer-causing PCBs.  Reeve says Monsanto was the sole manufacturer of PCBs until the chemicals were banned by Congress in the 1970s.  Reeve says the city of Portland has spent a large amount of taxpayer money to clean up PCB contamination in the Willamette River and Columbia Slough.
