The grand dreams of using the Seine in the Paris Olympics may have been better left as a dream. 

A massive effort was made to clean up the river, which had bacteria levels above what could safely be swum in, so it could be used in the triathlons as well as the mixed team relay. 

France Correspondent Catherine Field said that it’s already being seen as a mistake, simply because people now know what it takes to get the Seine clean. 

She said that France likely wanted the shots of swimmers in the Seine, but are now regretting it.
