Abstract

The article is devoted to justifying the feasibility of taking into account complex indicators of natural water quality in the task of regulating the discharge of pollutants with waste waters to water bodies. The problem has scientific and legal aspects. The scientific aspect is the similarity of the harmful effect of various substances on living organisms. Attention is drawn to the fact that in the tasks of normalization of discharge of waste water, it is advisable to calculate the complex negative effect of substances according to the limiting signs of harmfulness (LSH). Concerning the legal aspect of the problem, the article shows a contradiction between the normative and legal documents regulating the discharge of waste water, in terms of taking into account complex indicators. Namely, the current "Hygienic standards of water quality of water bodies to meet the drinking, household and other needs of the population" provide for the need to observe water quality taking into account LSHs, and in the "Rules for the protection of surface waters from pollution by waste waters" and "Methodological recommendations on the development of standards for the maximum permissible discharges (MDS) of pollutants into water bodies with waste waters" there is no requirement to take into account LSHs. Based on the analysis, a conclusion is made about the need to adjust the legislative and methodological documents that regulate the calculation of the MDS of pollutants to water bodies, in terms of taking into account complex indicators of the quality of natural water.
