Contaminated bags of sand and oil are loaded onto a track loader in Manhattan Beach, Calif., on Thursday, May 28, 2015. Popular beaches along nearly 7 miles of Los Angeles-area coastline are off-limits to surfing and swimming after balls of tar washed ashore. The beaches along south Santa Monica Bay appeared virtually free of oil Thursday morning after an overnight cleanup, but officials aren't sure if more tar will show up. (AP Photo/Nick Ut)
