Fed-up swimmers take on the Thames in fight against water pollution and tell lawmakers it's a "national scandal"

Open water swimmers in the River Thames.

Frustrated open water swimmers are calling on the British government to take immediate action to address the ongoing sewage crisis in British waters, after completing a 124 mile relay along the River Thames.

Athletes supported by the Surfers Against Sewage (SAS) campaigning charity set off from Gloucestershire in England on Monday, September 1, and swam, relay-style, to Teddington Lock, which they reached on Thursday, September 4. Participants then travelled, by boat, to the heart of Government in Westminster, where they urged lawmakers to take immediate action to protect Britain's rivers, lakes, and seas.
