CHARACTERISATION OF RUNOFF CONTAMINANTS FROM NEW ZEALAND ROADS, AND EFFECT OF RAINFALL EVENTS

Vehicular traffic on road asphalt generates a variety of inorganic and organic contaminants. These accumulate on the road surface in quantities that depend on the traffic and road conditions. During rainfall events, they are washed from the road surface and make a major contribution to stormwater pollution. This road runoff contains suspended and dissolved inorganic and organic contaminants, and is a problem, particularly in urban areas, because of its potential chronic toxicity for aquatic species in the recipient waterbodies. This project, carried out in 2001, was to investigate contaminants found in New Zealand road runoff and to characterise the components at source. It was also to determine how the relative concentrations, total load and characteristics change with the frequency and intensity of rainfall events. (a)
