Experts: BP disaster spilling the equivalent of two Exxon Valdezes a week.

Based on “sophisticated scientific analysis of seafloor video made available Wednesday,” Steve Wereley, an associate professor at Purdue University, told NPR the actual spill rate of the BP oil disaster is about 3 million gallons a day — 15 times the official guess of BP and the federal government. Another scientific expert, Eugene Chiang, a professor of astrophysics at the University of California, Berkeley, calculated the rate of flow to be between 840,000 and four million gallons a day. These estimates mean that the Deepwater Horizon wreckage could have spilled about five times as much oil as the 12-million-gallon Exxon Valdez disaster, with relief only guaranteed by BP in three more months. Watch video of oil flooding out of one of the two remaining leaks, which BP had suppressed for weeks:

On Tuesday, BP America president Lamar McKay testified under oath before the Senate that “you can’t measure what’s coming out at the seabed.”



In an email to ThinkProgress, Dr. Wereley clarifies: “My analysis is based strictly on what is seen in the video, so only one pipe and only for that brief period of time. I’m making no claims about what happened earlier or what may happen in the future.”
