I'd no idea. Eww.

Yes, the reef story is bogus, but this tidbit was interesting/gross, from a Milwaukeean's point of view.

In 2003, for example, the Associated Press reported on efforts by the city of Milwaukee to prevent used condoms from floating into Lake Michigan [...]:

"Workers for the Milwaukee Metropolitan Sewerage District Commission said they found only 50 or 60 condoms in the harbor after the fisherman's complaints, but the district has been paying an average of $460 per day for an employee to scoop spent condoms with long-handled nets from tanks at a wastewater treatment plant.

Crews also scoop any prophylactics from the lake."
