Accessible and indispensible freshwater resources for ecosystems and humans represent only 0.26% of total freshwater resources and are found in lakes, reservoirs, and rivers (the rest being confined to glaciers, permanent snow, groundwater, and in the form of vapors). Unfortunately, water pollution is a phenomenon as undesirable as it is frequent and widespread, being for the most part the result of anthropogenic (human) activities. As a result of pollution, water can undergo both physical and chemical changes that can lead to the degradation or destruction of aquatic ecosystems and limit the possibilities of use for various socio-economic purposes. This paper presents a preliminary study on the quality assessment of one of the most important rivers in the Republic of Moldova - the Bâc River, which crosses the capital Chisinau. Bâc River has an extremely high degree of pollution, as a result of poor management of water resources and lack of measures to protect its quality. The aim of the paper is to identify the main sources of pollution of the Bâc River and to identify the impact generated by them on the studied watercourse and surroundings. The identification of the pollution sources was done step by step, through satellite observations, from the source to the discharge point, completed with field observations. The impact generated by the identified pollution sources was highlighted by applying the method of impact networks. Thus, taking into account the identified pollution sources, we made recommendations to eliminate/reduce pollution and implicitly its effects, by identifying practical solutions and prevention measures, and considering that these actions will ensure the protection of the aquatic ecosystem and the overall environment.
