‘Alarmingly high': E.coli levels discovered in River Thames ahead of famous regatta

Harmful E.coli bacteria has been discovered at ‘alarmingly high’ levels in the U.K.’s River Thames just days before elite rowers are due to compete there for the international Henley Regatta. Water quality testing found E.coli bacteria up to 27 times the acceptable limit for bathing water. E.coli is a group of bacteria that can cause severe illness. Around 4,000 rowers are set to compete in 400 races for the regatta, which has taken place since 1839. The high levels of E.coli raise health concerns and highlight the impact of sewage pollution on waterways.
