Last I looked, the entire Green Bay side of Lake Michigan (from Green Bay up to Escanaba/Garden area) was under a PFAS advisory, as was the south western 1/3 of Superior (from Duluth to the Keeweenaw).

The stuff is everywhere. At least the raw sewage overflows from Milwaukee/Chicago mostly dilute and turn less toxic in the matter of months versus generations as is the case with PFAS.

Chicago almost never dumps sewage into the lake anymore. Haven’t yet this year even with all the major storms.

Unfortunately that's not true. While not entirely raw sewage, Chicago opened the locks at Navy Pier in July of this year...not all the water in the city can flow to those reservoirs unfortunately, there was just so much rain around 4th of July this year.

Swimming advisories were only in effect for a few hours after the lock was open for nearly 8. Things are getting better but we still have work to do.
