Influence of stormwater and CSOs on copper and benzo[a]pyrene in receiving waters – hydrodynamic modelling approach

• In this study the influence of urban stormwater discharges and combined sewer overflows on receiving water was investigated in the context of chemical risks and recreational water quality. Transport of copper and benzo[a]pyrene in the Göta River, running through the city of Gothenburg (Sweden), was simulated using a hydrodynamic model. The modelling results showed that during rain events the water quality along the river deteriorates for different periods of time, at times exceeding the guideline values established by the city of Gothenburg. The model can be used as an effective tool to prognosticate the water quality in the river.
