ABSTRACT:
Objective. The problem of the quality of water supply for the population of Ukraine is getting worse every year. This is one of the most important threats to the national security of Ukraine. Poor quality water can cause many infectious and non-infectious diseases. This confirms the need to monitor the quality of water from springs and drinking water consumed by the population.
Goal: åcological and hygienic assessment of the quality of drinking water consumed by the population of the Rivne region and the dynamics of its changes for the period 2010-2020.
Research methods: sanitary and hygienic, bibliometric, analytical.
Research results. The materials on the state of centralized and decentralized water supply of the urban and rural population of the Rivne region for 2010-2020 have been summarized and systematized. During this period, the percentage of inconsistency of water samples from sources of centralized water supply according to sanitary and chemical indicators increased by 1.06 times. Then, as from the centralized water supply network (MCSV) in 1.8 times. There was an alarming trend towards an increase in the non-compliance of water quality with MCV according to microbiological indicators: from 5.4% in 2010 to 19.8% in 2020. For rural water supply systems, it was established that the percentage of non-compliance above the regional average according to microbiological indicators was in Goshchanskyi (72.2% in 2020), Dubenskyi (28.8% in 2016), Kostopilskyi (80.0% in 2020), Mlynivskyi (42.37% in 2017), Rivneskyi (46.1% in 2015) and Zdolbunivskyi (50% in 2016) districts. It was found that the average regional indicator of non-compliance of drinking water from sources of decentralized water supply according to sanitary and chemical indicators increased 1.2 times over the studied period from 26.2% in 2010 to 31.8% in 2020. Average regional indicator of non-compliance of drinking water samples decentralized water supply according to microbiological indicators for 2010-2020 was characterized by constant growth: from 8.4% in 2010 to 30% in 2020.
Conclusion. Taking into account the threatening trend of deterioration of the quality of drinking water according to microbiological indicators, the need to take urgent measures regarding the introduction of modern technologies and means of water disinfection for drinking needs is substantiated.
