Cleaning Up Paris’s Poop River for the Olympics

The Seine is set to feature prominently in the Paris 2024 Olympics’
Opening Ceremony—and in its marathon swimming events. But this
urban waterway has been challenging to clean and keep clean after a
particularly wet summer and high bacterial counts. What can the
Parisian organizers learn from the revitalization of a U.S. river
that was so polluted that it inspired the creation of the
Environmental Protection Agency? Scientific American associate news
editor Allison Parshall takes us to the banks of the reformed
Cuyahoga River in Ohio.  Plus, she gives us a look at the
growing urban river swimming movement in Europe. Recommended
