There’s a century of toxic sludge hiding in the Gowanus Canal, but it may not be enough to stop a mega-developer from building on it
In November, gigantic yellow excavators began scooping up the poisonous sludge colloquially known as “black mayonnaise” from the Gowanus Canal in Brooklyn, New York – a momentous step in a prolonged cleanup effort, 10 years after the waterway’s designation as a Superfund site.
