Hygienic regulation of various water types at the present stage

Abstract

Introduction. In 2019-2020 as part of the implementation of the “regulatory guillotine” mechanism, there was revised or canceled a number of regulatory requirements including those related to the rationing of various types of water. The purpose of the work was to eliminate outdated requirements that do not meet modern conditions for ensuring sanitary and epidemiological well-being in the field of water use of the population. Materials and methods. The research materials in the field of hygienic regulation of waters were sanitary rules and norms for drinking, domestic and cultural water use, maximum allowable concentrations (MAC) and approximate permissible levels (APL) of chemicals in the water of water bodies for domestic drinking and cultural water use. Results. There were approved two interrelated documents including SanPiN 2.1.3684-21 and SanPiN 1.2.3685-21, in which the requirements for the main types of water are systematized. The revised and updated documents exclude provisions of a descriptive nature, methods and technologies for implementing mandatory requirements. A distinctive feature of the hygienic requirements for water was the use of the error value of the method for determining substances in assessing the compliance of pollution levels with hygienic standards. Hence, the requirement for metrological support of determination methods is mandatory. The standards included in SanPiN 1.2.3685-21 are harmonized considering international data, including WHO, and health risk assessment. On the base of these approaches in section III, concerning water hygiene standards, twenty one standard was harmonized by chemical factor, of which 7 were modified, 5 standards were added considering WHO recommendations, 8 - considering EU recommendations (hormones and antibiotics), 1 - considering recommendations of Uniform sanitary rules of EurAZEU, standards of 69 pesticide active ingredients that are listed in Section IX containing pesticide guidelines were excluded. In addition, the list of APLs includes standards for 9 new substances that were reviewed and approved by the Commission on State Sanitary and Epidemiological Regulation. Limitations. The limitations of the study are related to the fact that the changes and additions made to the sanitary and epidemiological requirements for various types of waters are not exhaustive and can be revised as the standards of new substances, data on the toxicity and danger of standardized compounds, modern water treatment technologies and expansion of water uses become available. Conclusion. The implementation of the principles of elimination of excessive regulation and harmonization of standards with international requirements made it possible to unify the system of hygienic standards for various types of water.
