Given the current climate changes and the increasing anthropogenic stress, maintaining the quality of natural resources is increasingly stringent. Water, a vital yet limited in time and space natural resource, deserves more and more attention. To maintain water quality at accepted values, we need monitoring measures to reduce the impact of human activities on water resources. This paper presents a study of downstream Mures River water quality. Water was sampled in February, April, May, June, July, August and September 2016 in the Ilia Pod sector. Analyses show that water was slightly basic and that the water flow was fluctuating (it depends on the amount of precipitation in the river basin. As for the oxygen regime, it was good: it decreased only in July while biochemical and chemical consumption of oxygen increased in April, May and June, pointing to a water nutrient load. Nitrate, nitrite and total nitrogen content was higher, ranking the water in the 2nd quality class, unlike phosphorus content, whose values are very low. The impact of human activities on Mures River water quality was low, with values slightly above maximum admitted limits in nitrogen and oxygen regimes.
