The present study represents the assessment of the Arieş River water quality in its headwaters, an area heavily affected by intensive tourism activities from the Arieşeni resort. The water quality was assessed using three biotic indices based on benthic invertebrate communities: the Extended Biotic Index (E.B.I.), the Biological Monitoring Working Party adapted for Poland (B.M.W.P.-PL) and the Average Score Per Taxon (A.S.P.T.). Seven sampling sites were considered, located both on the main river course and on its main tributaries from the Arieş River headwaters. The structure of the benthic invertebrate communities, together with their indicative values for water quality showed polluted waters at the source of the Arieş River, an area characterized by intense tourism. However, on going downstream, the river exhibited good and very good water quality, due to its self-cleaning capacity.
