The condition of the centralized drinking water supply continues to be a serious problem in ensuring the sanitary and epidemiological well-being of the population of the Voronezh Region, as it causes a certain risk to the health of the population of the region. The paper assesses the current state of centralized drinking water supply and sanitation in the towns Anna, Liski, Boguchar, Rossosh, which are the administrative centers of four municipal districts of the Voronezh region. The problems of providing the population of the region with high-quality drinking water and the ways of solving rational water supply were considered. In addition, based on the results of chemical analysis of samples taken from the distribution network, the quality of drinking water supplied to the population of the studied towns was established. The results of the analysis showed that the population of small towns in the Voronezh region consumes drinking water that does not meet hygienic requirements. Therefore, today it is necessary to strengthen monitoring and control over the quality of drinking water supply, and the population of small towns in the region should use household water aftertreatment filters.

ABSTRACT. The authors have created a geoinformation-analytical system (GIS) for integrated assessment and mapping of the ecological conditions of the territory according to the criteria of anthropogenic impact and quality of the urban environment, as well as the response of woody plants and the health of the child population (on the example of Voronezh -the largest industrial city of the Central Chernozem region).It has been identified that anthropogenic pollution is formed by the industrial-transport sector and varies with regard to the features of the functional planning infrastructure; near the industrial facilities of the petrochemical profile in the left-Bank sector of the city, conditions for the existence of woody plants significantly worsen, which is manifested in the inhibition of their development; child morbidity rate is significantly higher in industrially polluted neighborhoods with high load of pollutant emissions from industry and transport. The diseases primarily associated with pollution are congenital anomalies, neoplasms, endocrine pathology and diseases of the urogenital area.The industrial zone is the main contributor to the total pollution of air, but the transport zone is the main contributor to the total pollution of soil and snow cover.KEY WORDS: geographical information system, industrial pollution, health of the population, environmental assessment, Voronezh.
