Results are presented of two-day measurements of heavy metal concentrations (lead (Pb), cadmium (Cd), chromium (Cr), zinc (Zn) and copper (Cu)) along the Ondava river and its tributaries Tpola, Trnavka, (East Slovakia). Non-zero concentrations of the elements were found. According to the evaluation of lead, chrome and cadmium content, river water can be classified into the first quality class by Slovak standards. Slightly increased concentrations of zinc and copper are supposed to be due to the vicinity of wood mill (Bukoza Hencovce) and its outlet of polluted water. Relatively low river discharges during water sampling suggest that concentrations are close to its annual maximum
