The quality of stormwater mainly depends on the types of surfaces the stormwater encounter (roads, parking lots, roofs etc.). All types of constituents may cause problems during decentralised treatment, re/use, or detention of stormwater. The objective of the presented work was to propose a list of selected stormwater priority pollutants (SSPP), which can be used for assessing pollutant sources & fluxes, the behaviour, fate and toxicity of pollutants during passage through best management practices (BMPs) and the environmental risk associated with their subsequent dispersal in the environment. The methodology used in this study; Chemical Hazard Identification and Assessment Tool (CHIAT) aims at selecting the most relevant SSPP and contains five steps; Source characterisation, Recipient, receptor and criteria identification, Hazard and problem identification, Hazard assessment and Expert judgement. The SSPP-list identified consists of water quality parameters (BOD, COD, SS, nitrogen, pH and phosphorus); metals (cadmium, chromium (as chromate), copper, nickel, lead, platinum and zinc); PAHs (naphthalene, pyrene and benzo[a]pyrene); herbicides (pendimethalin, phenmedipham, glyphosate and terbutylazine); and xenobiotic organic compounds (XOCs) (nonylphenol ethoxylates, nonylphenol, pentachlorophenol, di(2-ethylhexyl)phthalate, PCB-28 and methyl tert-butyl ether) representing persistent and ubiquitous compounds as well as compounds deriving from specific anthropogenic sources.
