Abstract

The Kharaa river basin is ranked in the 5th of 29 river basins in terms of the economic importance and industrial production in Mongolia. However, this river basin has one of the smallest total area basins which is 26th of 29 river basins (1). As several research studies, there have been resulted that the Kharaa River Basin (KRB) is one of the highest populated river basins in Mongolia because of agricultural and industrial activities. Most drinking water source of inhabitants is provided by groundwater which is fed by KRB and livestock is mostly using surface water (2). Until recently, data on the hygienic quality of water resources in the KRB was limited and it was hardly found openly.
