Oil from Deepwater Horizon spill still causing damage in gulf 2 years later, scientists find

On Florida's Panhandle beaches, where local officials once fretted over how much oil washed in with each new tide, everything seems normal. The tourists have returned. The children have gone back to splashing in the surf and hunting for shells.

Every now and then, a tar ball as big as a fist washes ashore. That's the only apparent sign that the worst environmental disaster in U.S. history tainted these sugar-white sands two years ago.

But with an ultraviolet light, geologist James "Rip" Kirby has found evidence that the oil is still present, and possibly still a threat to beachgoers.

Tiny globs of it, mingled with the chemical dispersant that was supposed to break it up, have settled into the shallows, mingling with the shells, he said. When Kirby shines his light across the legs of a grad student who'd been in the water and showered, it shows orange blotches where the globs still stick to his skin.

"If I had grandkids playing in the surf, I wouldn't want them to come in contact with that," said Kirby, whose research is being overseen by the University of South Florida. "The dispersant accelerates the absorption by the skin."

As those blotches show, the gulf and its residents are still coping with the aftermath of the Deepwater Horizon disaster, which began with a fiery explosion aboard an offshore drilling rig on April 20, 2010.
