SUMMRY:
Objective. To study the dynamics of pollution of the water supply network of the city of Uzhhorod and settlements of the Transcarpathian region during 2018-2022.
Materials and methods. The objects of the study were the water supply network of the city of Uzhhorod and settlements of the Transcarpathian region. Analyzed statistical material of the "Transcarpathian Regional Center for Disease Control and Prevention of the Ministry of Health of Ukraine" regarding pollution of the water supply network of the city of Uzhhorod and settlements of the Transcarpathian region in dynamics during 2018-2022. The obtained materials were processed by the statistical method using the Microsoft Excel computer program.
Results. Of the total number of water fountains, namely 553, which were under the supervision of the "Transcarpathian Regional Center for Disease Control and Prevention of the Ministry of Health of Ukraine" during the years 2018-2022, 420 of them did not meet the requirements of DerzhSanPiN 2.2.4-171-10 "Hygienic requirements to drinking water intended for human consumption", which is 75.9%: 28.9% of them due to the lack of sanitary protection zones; 28.8% due to the lack of the necessary complex of sewage treatment facilities and 41.6% due to the lack of disinfection facilities
Also, during the 2018-2022 period, 8,597 samples of drinking water were examined for sanitary and chemical parameters from the water supply network of settlements in the Transcarpathian region, including 874 samples of drinking water from the water supply network of the Ministry of Health of Ukraine. Uzhgorod, which is 10.2% and 20021 water samples for microbiological indicators, including 3480 samples in the city of Uzhhorod, which is 17.4%.
On the basis of laboratory studies, it was established that a significant number of samples of drinking water from communal, departmental and village waterworks do not meet the requirements of the State Health and Safety and Environmental Protection Agency for sanitary-chemical and microbiological indicators. Their low quality is associated with wear and tear of the existing networks and equipment of the water system; insufficient financing of the needs of the water supply and sewerage industry; periodic power outages from water intakes, which causes additional bursts of emergency pipelines; due to pressure drops in the network, as well as insufficient capacity of some of the existing centralized water mains.
Conclusions.
1. A significant number of water bodies in the Transcarpathian region do not meet sanitary standards and regulations due to the lack of sanitary protection zones, the necessary complex of treatment facilities and the absence of disinfection facilities
2. A significant number of tested samples of drinking water from communal, departmental and rural waterworks do not meet the requirements of the State Health and Safety and Environmental Protection Agency for sanitary-chemical and microbiological indicators.
3. Permanent ecological and hygienic monitoring of water supply sources, ecological and hygienic monitoring of water treatment and water supply network is carried out.
