PARIS — The mayor of Paris is getting ready to swim in the Seine River, and to the skeptics who doubt it will be clean enough for the Olympics, she says, “Come, it will be quite a nice party.”

French officials sounded optimistic Thursday as they unveiled a huge underground reservoir that is key to the $1.4 billion project to address pollution in the iconic river.
