That's actually slightly misleading. There is oil washing up on the beaches of Alabama and the water has been closed for a while.
The oxygen level in the deep water has lessened to the extent that larger fish and sharks are now up in the surf -

That blog is excellent for see how a community is affect by and dealing with it. It's really hurting them down there; it's an area dependent on tourism. One skipper in the little marina we used a couple of years ago has killed himself. (I've been going since I was 13, so decades...) There's a wildlife refuge and turtles nest on the beach (I've seen them! They're so neat.)
Devastating.
