The Gowanus Canal, currently in the midst of a battle over Superfund status, now has Riverkeeper watching its slimy, green, polluted back. Reportedly the folks at the organization are prepared to sue property owners along it, "including the city, for ongoing pollution problems ... [including] illegally dumping garbage into the already fetid corpse of water." The litterbugs have 60 days to clean up before they'll file the suit.
