(PARIS) — Olympics organizers are banking on the sun and scorching temperatures to improve the water quality of the Seine River enough for triathletes to swim in it. [time-brightcove not-tgx=”true”] Otherwise, they could be feeling the heat. Concerns about the Paris river’s cleanliness postponed the men’s triathlon on Tuesday, with officials hoping the swimming portion of the race will soon be able to go forward in the long-polluted waterway following an expensive cleanup effort.
