New Orleans, February 14 (RHC)-- The 2010 Deepwater Horizon oil spill may have been 30% bigger than previously estimated.  A new study, published in the peer-reviewed journal Science Advances, used three-dimensional computer simulations to track the spilled oil, finding the contamination reached the Texas shore, the Florida Keys, the coast of Tampa and parts of the east coast of Florida. 

On April 20, 2010, an explosion on the BP Deepwater Horizon Macondo oil well drilling platform.  The resulting oil spill was one of the worst environmental disasters in U.S. history, which killed 11 workers and dumped at least 200 million gallons of oil into the Gulf of Mexico.
