Water is one of the natural resources most widespread on Earth, between living organisms and water being an indispensable link. The aim of this research was to assess the water quality of the Stânca-Costeşti accumulation based on the results obtained from the determination of physical- chemical parameters and toxic pollutants. Stânca-Costeşti accumulation is situated on the border between Romania and Moldova in Botosani County. The elements determined for each sample related to the studied section are represented by: pH, dissolved oxygen, biochemical oxygen demand (B.O.D.), nitrite, nitrate, chlorides, sulphates, cadmium, nickel, lead, zinc, copper and chromium. In order to establish the values of determined elements were applied standardized analytical methods. The average concentrations of analyzed heavy metals were below maximum permissible concentration for Ist class of quality. As a general conclusion based on these results, we can say that water from Stânca-Costeşti accumulation fall within the IInd class of quality in terms of the oxygen and in the Ist class of quality in terms of nutrients and heavy metals.
