The photo above shows giant bags being filled with sludge from the bottom of Little Lake Butte des Morts, part of a massive clean-up effort for the Fox River system that will cost local businesses over $1 billion. Cleaning up what? Trace amounts of PCBs dumped into the Fox River decades ago. From my perspective, it's not clear that they pose any danger buried in river sediments, but no expense is being spared to remove huge mounds of sediments for processing. It's a controversial issue.
The photo was taken last fall from the west side of the 441 bridge, looking to the south.
