The spatio-temporal change of rivers' waters quality in the Transbaikal territory and its dependence on anthropogenic factors are considered in this article. This work is based on the materials of hydrological and hydro chemical observations during 1986-2010 years, which were received from Transbaikal Territorial Administration Hydrometeorology and Environmental Monitoring in the accredited center for monitoring environmental pollution. It was pointed out that several water sources are characterized by varying degrees of degradation in the Transbaikal territory. It was found as a result of the analysis of influence different anthropogenic factors that the main sources of water resources pollution are wastewater of energy complex organizations, mining companies, and wastewater treatment plants of public utility sector in the Transbaikal territory. Waterways of the Amur basin are very vulnerable to pollution in the Transbaikal territory, because it is the most previously-developed area in the region. Three Rivers are highlighted in this region, the waters quality of which is the lowest one in the basin. There are the Chita River with downstream, the Ingoda with middle and lower stream and the Argun. The main pollutants sources of the Amur basins rivers are biogenous elements, chemical detergents and chlororganic pesticides. Minerals such as iron, zinc, copper, organic matter and others are chemical and their content exceeds the maximum allowable concentrations in the Lena River dasin and the Lake Baikal. The presence and amount of nitrogenous components, phosphorous, petroleum products, chemical detergents and chlororganic pesticides in rivers of the Transbaikal territory could be explained by anthropogenic impact. Organic matter, iron, zinc, copper, phenols flow into rivers waters from both natural and man-made sources.
