I'd be very careful, here.  Remediation of river sediment is tricky.  If
you want to treat the sediment in the river, whatever agent you use must
not have a deleterious effect on aquatic organisms or plants, or people.

Removing the sediment to treat it is also problematic.  Since the dioxins
are bound to the sediment, they stay in place unless the sediment is
stirred up.  Dredging will mobilize the sediment/dioxins and they will move
down stream.
