BP’s latest attempt to contain the worst oil spill in US history has hit a new snag as the size of the disaster continues to grow. On Wednesday, a large underwater saw got stuck for twelve hours while slicing through the underwater well. BP says it will try again to cut off and then cap the well, but the flow of oil could temporarily increase by as much as 20 percent even if it succeeds. In an interview with the Financial Times, BP CEO Tony Hayward admitted the company wasn’t prepared to handle the spill, saying, “What is undoubtedly true is that we did not have the tools you would want in your tool kit.” The White House, meanwhile, has ordered BP to pay for five more Louisiana barrier island sand berms to contain the spill. The berms will cost around $360 million.

Blobs of oil are now reaching nearby states. Workers have scooped oil from the shores of Dauphin Island, Alabama and parts of Mississippi. And the oil sheen is now about ten miles from the Florida Panhandle. In other spill news, the National Oceanic and Atmospheric Administration has launched a research vessel to probe findings of large oil plumes trapped underseas. BP has challenged scientists’ claims to have discovered the Gulf plumes.
