In the article pollution of stream waters with surface runoff from an urbanized area caused by an extremely high rainfall is discussed. The analyzes were carried out after the rainfall of the depth 152 mm which took place in Gdańsk on 14th and 15th July 2016. This extreme rainfall caused urban flooding, damage of several retention ponds and pollution of surface waters. In the article the results of physical and chemical analyzes of the water samples from Oliwski Stream, inflowing to the Gulf of Gdańsk at the beach in Jelitkowo, are presented. The samples were collected at six points along the Stream in order to evaluate potential pollution sources. The results of the study indicated elevated concentrations of phosphorus compounds and nitrates (V). Additionally, the concentrations of total suspended solids (TSS), solids granulometry and grain size distribution along the stream was investigated.
