Sadly, this is yet another monumental EPA screw-up.
For one thing, the dredging will likely makes things worse, but more than that, NO human health effects have ever been documented on the area workers, exposed to PCBs.
In 1999, the Agency for Toxic Substances and Disease Registry (ATSDR)—a unit of the CDC—concluded that "The weight of evidence does not support a causal association for PCBs and human cancer at this time."
Apparently, this was not the PC finding, though, because they reversed it in 2000, for no scientific reason whatsoever.
Yes, friends, this whole business stinks to high heaven.
