SUMMÀRY:
Water is one of the most important elements of the external environment, without which life is impossible. Water takes part in almost all vital processes in the body. Mass diseases of the population of both infectious and non-infectious nature are the most threatening negative consequence of the use of poor-quality water.
Objective of the study. To investigate bacterial contamination of the water supply network of Uzhhorod and the settlements of the Transcarpathian region in dynamics during the period from 2020 to 2024.
Materials and methods. The analysis was conducted of the statistical data from the State Institution "Transcarpathian Regional Center for Disease Control and Prevention of the Ministry of Health of Ukraine" regarding bacterial contamination of the water supply network of Uzhhorod and the settlements of the Transcarpathian region in dynamics during 2020-2024. The obtained data were processed by statistical methods using the Microsoft Excel software program.
Results. The laboratory study of selected water samples from the water supply network of the city of Uzhhorod and settlements of the Transcarpathian region in dynamics during 2020-2024 was conducted. The main factors of pollution of the water supply network of the city of Uzhhorod and settlements of the Transcarpathian region were identified and determined, and a number of measures were developed to prevent their pollution.
Conclusions.
1. A significant number of water supply systems in the Transcarpathian region do not comply with sanitary standards and rules due to the lack of sanitary protection zones, the lack of the necessary complex of treatment facilities, and the lack of disinfection facilities.
2. A significant number of tested water samples from the water supply network of both Uzhgorod and other settlements of the Transcarpathian region do not meet the requirements of the State Standard for microbiological indicators.
3. A number of measures have been developed to prevent contamination of drinking water from various water supply systems, namely: reconstruction of pumping stations, replacement of water inlets and pumps in some artesian wells, reconstruction of certain water supply pipelines and networks, equipping of water supply chambers with pressure regulators, reconstruction of the water supply systems in several schools, hospitals, and villages in the Transcarpathian region. Adequate funding for the construction and reconstruction of most sewage and water supply facilities could significantly improve the quality of drinking water.
