The U.S. Navy has set aside US$200 million for the cleanup on Vieques, authorities announced last month. The Navy previously used Vieques as its main Atlantic training site, combining air, sea and land maneuvers. About 775 acres have been cleared since the cleanup began in 2005, according to authorities. (AP Photo/Brennan Linsley)
