One of the reasons for the current global environmental crisis is the intense anthropogenic impact on water bodies, which results in their depletion and pollution. The source of the negative impact is, in particular, insufficiently treated wastewater from industrial enterprises. Depending on the technological processes used, toxicants can enter the water bodies along with the effluents, which pose a serious threat to them. The aim of the work is to consider the features of water supply and wastewater disposal of enterprises that make up the industrial hub of the city of Tambov. The work used methods of analysis of technical documentation and statistical reporting characterizing the qualitative and quantitative composition of wastewater. Water supply of the considered enterprises is carried out from the city water supply network and own artesian wells. All enterprises do not have full-fledged treatment facilities capable of carrying out a full cycle of wastewater treatment with bringing them to a standard clean state. The use of galvanic technologies in production requires preliminary cleaning at local treatment facilities. Then the wastewater goes to the city wastewater treatment plant, where it is processed together with the municipal wastewater. Normally clean and storm water flows directly into the surface water body. The largest enterprise of the industrial hub pumps its industrial effluents into deep aquifers. Over the entire period of its operation, over 52 million m3 of liquid toxic waste was injected. As a result, a zone of contaminated groundwater was formed under the enterprise and adjacent territories. In them, the excess of the maximum permissible concentrations for a number of parameters is constantly noted. Thus, this enterprise is a source of powerful, direct negative impact on groundwater and, indirectly, on surface water. This led to the emergence of a zone of sustainable environmental risk.
