not just mercury, but cadmium and radioactive thorium as well; at least up here farther north. The watershed around Kress Creek was a Superfund site from an old Kerr-McGee plant that dumped untold amounts of toxic waste into the Kress. That flowed into the W Branch just about a mile or two downstream. You can be sure some went all the way down past the confluence and beyond.

"There are four Kerr-McGee Superfund sites. The sites were contaminated by radioactive thorium waste material generated by a processing facility, known as the Rare Earths Facility, which operated in West Chicago between 1932 and 1973. The West Chicago Environmental Response Trust is cleaning up the sites and the Rare Earths Facility under a Tronox (formerly Kerr-McGee) bankruptcy settlement.
The Kress Creek/West Branch DuPage River site includes almost seven miles of creek and river sediment, banks and floodplain soils contaminated with radioactive thorium residue." (from http://www.dredgingtoday.com/2011/04/21 ... eanup-usa/
