Exclusive: Hundreds of anglers take part in UK's largest citizen science water-testing project

Eighty-three per cent of English rivers contain evidence of high pollution caused by sewage and agricultural waste, according to the largest citizen science water testing project ever to take place in the UK.

Hundreds of anglers took part in the study, organised by the Angling Trust, after being angered by the brown blooms of sewage in the waters they painstakingly tend for the benefit of fish.
