Despite the fact that substantial water resources are concentrated in the Irkutsk region, the research revealed the problems of providing the population with high-quality drinking water from centralized water supply systems. Monitoring the quality of drinking water from centralized water supply showed the presence of sources that do not meet sanitary and epidemiological requirements, which is associated in the overwhelming majority of cases with the absence of sanitary protection zones. The discrepancy with the adopted regulations of a part of sanitary-chemical and microbiological samples of drinking water was revealed. Deviations are mainly caused by an excess of the content of iron, aluminum, manganese, nitrates, magnesium, as well as general and thermotolerant coliform bacteria. The reasons for the unsatisfactory state of drinking water are detected and measures are recommended to ensure the appropriate quality for the sustainable development of the area under research.
