Bandera Str. 12, Lviv, 79013, Ukraine * Corresponding author’s e-mail: [email protected] ABSTRACT The article describes the steps for organizing and conducting the ecological monitoring of surface water in order to shift Ukraine to the European standards in the field of water use and protection. The main water users-pollutants of the Western Bug River basin in the Lviv region were identified. The results of the water samples taken from the control bodies in 2018 were analyzed. A promising way to improve the work of the water basin management of the Western Bug River was proposed. Keywords: the Western Bug River, river basin, EU Water Framework Directive, monitoring, quality of surface waters. INTRODUCTION with the use of GIS technologies.
