RIO DE JANEIRO (AP) " The sewage-filled waters off Copacabana weren't much of an issue for the open water swimmers. The winning margin was a staggering 17.4 seconds, far more than the 0.4 difference four years ago and the 1.4 spread at the inaugural open water competition in 2008. Brazil's Poliana Okimoto went from just off the podium to bronze " the first swimming medal ever won by a Brazilian woman, either in the pool or open water. The inaugural open water event in 2008 was staged at Beijing's rowing and canoeing canal. Four years ago, the open water in London took place in the Serpentine lake at Hyde Park.
