Enfield Council is utilizing a new tool developed by Thames21 and the British Geological Survey to identify road sections contributing to river pollution. This tool employs data on pollutant emissions, rainfall, surface area, and traffic to predict pollution hotspots and offers nature-based solutions, like rain gardens, to mitigate runoff before it impacts rivers. Research by Professor Lian Lundy highlights the importance of addressing road runoff due to its detrimental effects on river health, drinking water sources, and wildlife habitats. The project, funded by various agencies, has mapped approximately 2,400 miles of London's major roads and revealed substantial pollution levels affecting river ecosystems.
This tool supports authorities who manage rivers to identify where hotspots for road run off river pollution are likely to occur.
There are more than 300 different forms of pollutants which come from everything from the exhaust emissions, to the brakes and the tyres and the degradation of the road.
