The Guardian reported marine protection officers overseeing the cruise liner clean up fear 2,400 tons of fuel could leak out into surrounding waters if any of the ship's tanks are broken.

From The Guardian:

The region is already reeling from an accident in December when a cargo ship near the island of Gorgona lost 198 barrels of toxic cobalt-nickel material overboard in rough weather. The barrels have not been recovered.

As journalists and rescuers crowded on to the dock at Giglio, mayor Sergio Ortelli warned against "alarmism" that could damage this summer's tourist business.

"It is true that the fuel is split into 15 tanks, which means that even if the ship plummets down, not all will crack, and not all the 2,400 tonnes will be released in one go," said Poggi. "But if any is released it would be a disaster anyway."

The Italian environment ministry has warned that the ship is already polluting the granite shallows in which it rests, as tonnes of cooking oil, paint, detergents, solvents and chlorinated swimming pool water seep out from the holes punched in the hull by divers.

Earlier on Saturday, reports came that the death toll had risen to 12 after the body of a woman had been recovered following the Jan. 14 accident. Twenty more people are still missing. Captain Francesco Schettino has been placed under house arrest and faces charges of manslaughter and abandoning ship.
