Wide range of pollutants
Over 300 pollutants in road runoff.
Diffuse pollution
Difficult to track and quantify because of its intermittent nature.
Temporal nature
Most polluted after long dry spells.
Difficult to prioritise
Making challenging to implement NbS.

Predicted total concentrations
Mass of each pollutant deposited on a road surface per vehicle type was identified.
Integrated pollution classification
To support use of results, predicted road runoff pollutant concentrations were allocated to one of four categories.
SuDS selection
Identifies potential locations for constructed wetlands and other NbS.
Greenspaces
Identify greenspace areas for selected outfall points.
