Despite being a Detroiter, I had to learn about the Windsor Hum from the Guardian UK. The plant on the charming and charmingly named Zug Island was long suspected. US investigators wouldn’t do anything, despite the profusion of complaints from across the Detroit River.
Zug Island’s doings, in concert with a Downriver oil company, made Southwest Detroit stink to highest heaven and lowest hell.
I’m relieved to see us steel is finally being forced to face consequences, after decades of their heinous misbehavior. dow chemical also spent decades poisoning the Detroit River. When they were forced to shut down and clean up, the River almost immediately improved.
Whoever is responsible for the Halifax Hum damn well knows it, won’t fix it, and won’t fess up. Simply delightful.
