Feds: Oil Spill Not Such a Disaster After All! Only 26% of BP leak is still lurking in the Gulf By Kevin Spak, Newser Staff Posted Aug 4, 2010 10:36 AM CDT 29 comments Comments A boat motors through oil sheen from the Deepwater Horizon oil spill off East Grand Terre Island on the Louisiana coast, Saturday, July 31, 2010. (AP Photo/Gerald Herbert) (Newser) – The government has decided that the Deepwater Horizon spill wasn’t such a big deal after all. According to a new report coming out today, three-quarters of the oil has already evaporated, dispersed, been captured or otherwise disappeared, according to the New York Times, and most of the remaining 26% is light sheen that should quickly break down. And officials say they’re pretty confident about their calculations. “There’s absolutely no evidence that there’s any significant concentration of oil out there we haven’t accounted for,” says the head of the National Oceanic and Atmospheric Administration. But “I think we don’t know yet the full impact of this spill on the ecosystem or the people of the Gulf,” she added.
