Abstract: The aim of this study was to assess the seasonal variability of the chemical composition in the Biała River flowing through the urban area. The Biała River is not heavily polluted. Average EC25 ranged from 450 μS·cm–1 in the upper course of the river to 838 μS·cm–1 in its lower course. The highest nitrate concentration was found in most sampling points in May and July 2009 and in March 2010. Ammonium concentration ranged from 0.07 to 1.34 mg·dm–3. The highest N-NH4 + was found in November 2009 and in March 2010, in the periods of the lowest biological activity. The concentration of phosphates was similar in the water on the studied section of river. The lowest PO4 3– concentration was measured in November 2009. Chloride concentration ranged from 16.3 to 56.0 mg·dm–3. The highest Cl– concentration in March 2010 is the result of winter road maintenance.
