During the cleaning of the gully pot, water has to be added to the gully pot to remove all the sediment. This mixture of gully pot water and sediment, as well as the "wash-water," has to be taken care of. This paper considers the quality of the water phase of this mixture, due to a wide spectrum of metals and organic substances. Three sampling sites were selected according to type of area and traffic intensity. The samples were analysed for suspended solids (SS), heavy metals, PAH, DEHP, and NPEO. The highest total concentration of metals was found either in the housing area or in the city with high traffic, depending on the type of metal. The highest concentration of PAH was found in the city with medium traffic. Most of the metals and PAH were attached to particles. Even if the concentrations were higher in the housing area, one will get higher amounts of metals from the city during the same period of time. The comparison between guidelines and the blend showed that the concentration in the blend exceeds the discharge criteria for most of the substances.
