|PCB sediment contamination is a serious health problem for the Fox
River, Green Bay and Lake Michigan (one of the five Great Lakes of North
America). Up to 70% of the waterborne PCBs entering Lake Michigan
ultimately come from 7 paper companies along the Fox River in Northeast
PCBs, otherwise known as "polychlorinated biphenyls," are actually
a family of 209 chemicals, which differ only in the number and position
of chlorine atoms around the outside of the molecule. The different
shapes mean each PCB type behaves at least slightly differently.
We have a broad mixture of most PCB types in the Fox River.
