Our work was focused on physico-chemical and biological characteristics of Aries River, one of the largest rivers from Romania. Water samples were collected from 11 sites along Aries River course. We have measured de 18O and D isotopic composition of Aries River water in these locations and correlated these data with the isotopic composition of aquatic plants and with the pollution degree. Some ions from Aries River water were also analyzed: NO3−, NO2−, PO43− Cu2+, Fe3+. Analysis of diatom communities has been performed in order to quantify the level of water pollution of Aries River. All physico-chemical analyses revealed that the most polluted site is Abrud; the source of pollution is most probably the mining enterprise from Rosia Montana. Water isotope content increases from upstream to downstream of the locations analyzed. The structure of diatom communities is strongly influenced by the different pollution sources from this area: mine waters, industrial waters, waste products, land cleaning, tourism etc. The water eutrophication increases from upstream of Campeni to downstream of Campia Turzii.
