Floating +Pool would let New Yorkers swim in the river

Floating +Pool would let New Yorkers swim in the river: "It's a hot summer day, you're sweaty and uncomfortable, and there's a river full of cool, clear water right beside you. Do you jump in? Not if you're in New York City, as the rivers that flow through that city are too polluted for swimming ... or at the very least, that's the perception that most people have of them."
