Oil still being found 3 years later from rig explosion

(CNN) — Three years after the Deepwater Horizon oil spill, workers have dug up a massive chunk of weathered crude from the shallows off a Louisiana beach.

The tar mat — a slab of oil residue mixed with wet sand — was about 165 feet long by 65 feet wide, said Lt. Cmdr. Natalie Murphy, a Coast Guard spokeswoman. It weighed more than 40,000 pounds, but more than 85% of that weight was sand, shells and water, she said.

The mat was found under the surf off Isle Grand Terre, Louisiana, about 90 miles south of New Orleans. Crews using an excavator dug the largely submerged tar mat out of the beach in chunks over the last few weeks, Murphy said.

Louisiana is the last state where regular cleanup operations from the oil spill are still under way. The Coast Guard and BP, the owner of the ruptured well at the heart of the disaster, declared the cleanup over in Alabama, Florida and Mississippi earlier this month, but more than 80 miles of the Louisiana coast are still being patrolled.

BP has recovered more than 2.7 million pounds of waste from Louisiana shores in 2013, with residual oil making up between 5 and 15% of that total weight, company spokesman Jason Ryan told CNN.

The drill rig Deepwater Horizon exploded and sank in April 2010, killing 11 men aboard and unleashing an undersea gusher a mile beneath the surface of the Gulf of Mexico. Most of the oil is believed to have evaporated or been consumed by microbes deep under water. But a still-undetermined portion settled to the floor of the Gulf, and some of it was stirred up and washed back ashore after Hurricane Isaac in 2012.

    This is horrible that their is still oil being found after 3 years. Either they are doing a terrible job cleaning up or the spill was just that large. Its hard to think that their would be oil 3 years later but theirs nothing we can do about it except for keep cleaning. Thanks for the article!
