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.
