Not impossible, Dog. Just very, very expensive. Which I think was probably your point. They're dredging and removing some old damns on the Kalamazoo River near me. There are PBC's in the sediment. The issue of course is what to do with the sediment.
In practise, what happens is that these things are trucked to a landfill, once an acceptable site can be found. What that tends to do is to concentrate them and magnify any problem they can cause if there is leakage. There are solutions, such as incineration, but the costs and conflicts are high. Ultimately though, once again, the solution is dilution. Were they not diluted and thus less harmful, while on the river bottom, we'd have had them out of there long ago.
Eventually, they'll probably dredge your river and remove them. The concern is that in doing so they stir everything up and down stream it goes. Once again though the solution is dilution and the effects will probably be transitory. It doesn't help that there is thirty additional years of sediment on top of them which must be removed and is considered hazardous waste as well.
