Catherine Porter of the NYT gives this story of how the French are finally, finally cleaning up the Seine river in Paris. Under a Swimming plan workers are cleaning up the river so that long distance swimming for the 2024 Olympics happens inside the river itself. During rainstorms 40 portholes dotting the river's paved banks gush with sewage. Some homes along the river dump sewage right into the river, industrial waste also is dumped into the river. It was not always so, in the 1900 Olympics 7 swimming events happened in the river. Swimming was banned in the river in 1923 and today it is murky, and seen as hazardous for swimming. Studies from the 1990's onwards showed it has one of the highest heavy metals in the world in the stretch running through Paris.
