VENICE, La. -- Francisco Banda, a contract worker for the Deepwater Horizon response cleanup, gathers sorbent boom from the marshes around the Mississippi River in Plaquemines Parish, Sept. 4, 2010. Boom is reeled in by the "boom eater," an invention, by Tha Hua, designed so boom could be retrieved more efficiently and safely. U.S. Coast Guard photo by Petty Officer 3rd Class Angela Henderson.
