Calls have been made for action to stop "huge poo islands" forming in a county's rivers.
In September 2020 a damning report by the Environment Agency found that all of Somerset's rivers were "polluted beyond legal limits".
It was put down to chemical pollution and sewage being discharged into the watercourses. One councillor said that he had been contacted by a local resident who had encountered sewage while wild swimming in the River Tone.
