Scientific substantiation of conceptual approaches to the development of a regulatory document on the quality of drinking water under condition of martial law

Abstract

The purpose of the research was to scientifically substantiate the conceptual approaches to the development of normative document on drinking water quality in order to prevent morbidity and mortality in martial law during armed aggression in Ukraine and other emergencies. Materials and methods: descriptive, sanitary-chemical, normative-search, comparative analysis, expert assessments have been used. The paper analyzes the results of observations of efficiency and monitoring of water quality from water supply stations of Ukraine before and after the war, and compare assessment of the main provisions of regulations on drinking water quality of some countries, including those used in emergencies. Results. The research established that in wartime centralized drinking water supply companies are burdened by problems due to unguaranteed quality of source water, lack of stable conditions for the technological process of water treatment, operation or destruction of water treatment plants and networks etc. Current standards in Ukraine( DSanPiN 2.2.4-171-10 "Hygienic requirements for drinking water intended for human consumption") during martial law require significant changes: supplementation of safety and quality indicators due to the new risks of drinking water pollution; exclusion of certain safety and quality indicators at the expense of non-priority ones; establishment of temporary hygienic standards for tap water and water dispensing points and the procedure for their use; adjusting the frequency of production control of potable water; implementation preventive measures to reduce morbidity and mortality. Today the project of “DSanPiN "Safety indicators and some particular indicators of potable water quality during martial law and emergencies of another nature" (hereinafter - DSanPiN) has been scientifically substantiated and developed. According to the draft of this document, the quality of drinking water in terms of epidemic and radiation safety must meet the requirements of DSanPiN 2.2.4-171; in terms of physicochemical - see requirements of DSanPiN. The requirements of DSanPiN after their state registration will be applied during martial law and during emergencies of other nature in a particular area for a specified period as short as possible by the relevant regional or local commission for technogeneous environmental safety and emergencies. Conclusions. It is established that during the military emergency situation in Ukraine the current DSanPiN 2.2.4-171-10 "Hygienic requirements for potable water intended for human consumption" require significant changes in order to: supplement safety indicators due to the emergence of new risks of drinking water pollution; exclude certain indicators of safety and quality due to non-priority; establish temporary hygienic standards for potable tap water and bottling points in personal containers of consumers and the procedure for their use; adjust the frequency of production control of potable water quality; implement other preventive measures to reduce morbidity and mortality.. Nowadays the draft DSanPiN "Safety indicators and some indicators of potable water quality in martial law and emergencies of other nature" is scientifically substantiated and developed, and it was submitted to the Ministry of Justice of Ukraine for state registration.
