Abstract:
The maintenance and increase of safe drinking water supply, hygiene and sanitation, and proper water management are fundamental to human health in all countries and regions of the world. Efforts to improve the chemical composition of drinking water, sanitation, and hygiene interact with each other and actively contribute to the health and public well-being.
[...] Load More Because of the topic urgency, the purpose of the study was to justify the maximum permissible limit of component mineral composition of drinking water as an impact factor on the general health status of the population. The object of research has been chosen because the population of this region uses an artesian water supply for more than 30 years. As a result, the hardness level of drinking water permanently increases in comparison with surface water sources. In the framework of this study, using the method of comparative analysis of standards of water quality hydrochemical indicators and level of pollution (specified in sanitary and epidemiological rules), the pollution level and quality of artesian water supply has been justified. Supplied water by its properties (mineralization and ionic composition) meets sanitary standards for drinking water; however, it does not fully meet the optimal physiological parameters due to the reduction of some chemical elements necessary for the body and because of the concentration level of toxic chemicals. With the use of the correlation analysis method, a direct proportion between the disease incidence among the adult population and the level of chemical elements contained in drinking water of artesian well drinking-water supply has been justified. Gradation of disease incidence levels among the adult population of the region to "high level of intensity" and "low level of intensity" depending on maximum permissible regulated norms of concentration of chemical elements in drinking water has been implemented. Quantitative standards of hydrochemical indicators of drinking water quality based on the concentration level of toxic and essential chemical elements were substantiated and recommended. The obtained research results are practical and can be used by sanitary services to improve standards of drinking water quality assessment as well as design, construction, operation of water supply systems, and provision of drinking water to the population.
