River Thames

Yes you can actually swim in the Thames now, and no not in the section that runs through central London. A spot on the Thames between Kingston and Ham has become first official bathing site on the river as part of a plan by the government to increase the number of official bathing sites in England to 464. Pollution has affected the Thames for decades, with the river even being declared biologically dead in the 1950s, so this designation represents a “vast transformation” in water quality.
