Water is a strategic resource that ensures the livelihood of the population and the economic development of society as a whole. The solution to the water supply issue has been included in the Sustainable Development Goals, which prioritize access to water for all by 2030 to reduce social and medical inequalities. Due to pollution and the withdrawal of a significant number of natural water from use, access to clean water has become significantly limited. For our country, the issue of drinking water supply has acquired special importance in the context of the war between rf and Ukraine. Research on water quality indicators for compliance with sanitary and hygienic standards is an essential component in the search and exploitation of potential water sources.The aim of the work was to study the quality indicators of drinking water from centralized and open water supply sources for the population of certain territorial communities in the Lviv region, in accordance with national and European regulations. The experimental samples included water from centralized (Stronyatyn water intake) and open («Maidan» tract) water supply sources. The compliance of drinking water quality with sanitary and hygienic requirements was investigated using standardized methods.Results. Given the water supply problems, the population independently began searching for environmentally clean water sources that are not only suitable for drinking but also have health-improving properties. The quality of drinking water from centralized water supply (the Stronyatyn intake) didn’t meet hygienic requirements based on organoleptic (taste – 3 points, astringent), physico-and-chemical (hard- ness – 13,44 mmol/dm³, iron content – 1,8 mg/dm³, total mineralization – 1 080,0 mg/dm³) indicators and was characterized by increased electrical conductivity (2 160 µS/cm). The quality of drinking water from the open source in the “Maidan” tract met national and European regulations in terms of organoleptic, physico-and-chemical, and sanitary-toxicological indicators. Conclusions. The results of the research can be used to predict the health status of the population and develop measures to improve the quality of drinking water and water supply to territorial communities in the region.
