The article presents the results of a comprehensive assessment of the ecological state of water objects Basin Donets using indicators that characterize the level of anthropogenic pollution of abiotic and biotic components of aquatic ecosystems. It is shown that water quality in the 25 cross-sections of rivers Seversky Donets, Uda, Lopan, Kharkiv, Oskol, Nemyshlya, Suhoy Torets and Pechenga and Krasnooskolskogo reservoirs in 2011 - 2012 did not meet the standards of fishery MPC (the state of the abiotic component), and in 52% of cases (2011) and 64% (2012) did not meet the quality standards for ecotoxicological indicator (status of biotic components of aquatic ecosystems). The poor ecological state of water objects Basin Donets is the result of discharge to surface water bodies basin wastewater contaminated with environmentally hazardous chemicals.
