Goal. To carry out an ecological and hygienic assessment of the quality of drinking water and the state of water supply for the population of Volodymyrets district from sources of centralized and decentralized water supply.
Objective. The object of the study is drinking water from sources of centralized and decentralized water supply in Volodymyrets district, Rivne region.
Materials and methods. The work uses data and materials from the Rivne Regional Laboratory Center of the Ministry of Health of Ukraine and the Department of Ecology of the Rivne Regional State Administration for the period 2015-2019. During the research, the following methods were used: sanitary-hygienic, mathematical-statistical, epidemiological, theoretical (analysis, comparison, generalization).
Results. Monitoring observations and data analysis of the results of laboratory studies of drinking water according to sanitary-chemical and microbiological indicators from the sources of centralized and decentralized water supply of the Volodymyrets district of the Rivne region for the period 2015-2019 were carried out. It was established that the quality of drinking water from the sources of centralized and decentralized water supply in the Volodymyrets district, according to sanitary-chemical and microbiological indicators, is deteriorating during the studied period. The study of the dynamics of non-compliance of drinking water quality indicators from centralized water supply sources showed that the percentage of non-compliance of samples according to sanitary and chemical indicators during 20152019 increased almost 1.4 times from 41.9% in 2015 to 60.6% in 2019. In general, drinking water does not meet regulatory values for iron content, color, and turbidity. It is also noted that the rate of non-compliance by microbiological indicators increased by 1.4 times from 17% in 2015 to 22,6% in 2019. From decentralized sources, the percentage of non-compliance by sanitary and chemical indicators during 2015-2019 increased by 1.8 times from 23.9% to 43.8%, with the largest deviation of 71.4% (3.1 times) in 2018. For sources of decentralized water supply, the defining risks are: inconsistency in the locations and arrangement of private wells in accordance with sanitary standards and violation of operating rules due to their location near latrines, cesspools, sewerage networks, places where livestock are kept, and the non-compliance of the quality of drinking water with regulatory requirements for the content of iron, nitrates, color and pH. According to microbiological indicators, there was a fluctuation during the studied period from 50.0% in 2015 to 53.8% in 2019. It is recommended that the local self-government bodies develop a perspective plan for improving the material and technical condition of the district's water pipelines.
