The Obama Administration's latest report [1]on the Deepwater Horizon cleanup efforts, which was based on modeling, was not well received by scientists or Gulf Coast residents. In reference to the report's "very generous assumptions," one University of Georgia marine scientist asserted “If an academic scientist put something like this out there, it would get torpedoed into a billion pieces." The report concluded that 26 percent of the oil, or 53 million gallons, had come ashore or has not yet degraded in the water.
