A huge citizen testing blitz of rivers across Britain this summer has found 75% are in poor ecological health as a result of pollution from water companies and agricultural runoff.
Rivers in the south-east and East Anglia regions of England, including the Thames basin, were found to be among those in the worst state, with 89% of rivers failing to meet tests for good ecological health in those areas, according to the results of the monitoring by volunteers for Earthwatch Europe.
