The aim of this study was to establish the correlation between natural water pollutions and the prevalence of heart diseases. We analyzed the data from the 2014 Federal Service Report on the state of sanitary and epidemiological welfare of the population. The correlation analysis of data on mortality and primary morbidity of the population was carried out, the correlation between the quality of natural water and cardiovascular diseases of the population was established. The complex method of water quality assessment according to the data of hydrochemical monitoring of the Azov Sea and rivers flowing into it were used in the investigation, the influence of the main pollutants such as copper and manganese on the dynamics of cardiovascular diseases according to mortality and primary morbidity for the population of Taganrog was considered. As conclusion we can state that statistical association between water intake and heart diseases exists in the region of analysis. However, further studies on water intake are needed to confirm our findings.

The system of life evaluation, combining an objective component (indicators of water quality, morbidity) and subjective (the degree of satisfaction of residents with water quality) was developed. The system of life comfort includes information on people morbidity and the main consumed water parameters that affect the satisfaction of water resources and health. Such system units as «Input Interface» and «User Interface» have been developed in MS Access and are presented in the paper. In addition system includes geographic information system that allows visualizing, analyzing and predicting the state of the object. The main features of the system are shown and recommendations for its application are offered.

The quality of human life consists of many parameters: physical, psychological, level of independence, social life and the environment. The latter, in turn, includes safety, ecology, security, availability and quality of medical care, information, training opportunities, and life. The system of life quality evaluation, combining an objective component (indicators of water and air quality, morbidity) and subjective (the degree of satisfaction of residents with water quality) was developed. “Crowd survey” data block realizes the function of “Open access”. The system of life comfort includes information on people morbidity and the main consumed water and air parameters that affect the satisfaction with natural resources and health. Such system units as «Input Interface» and «Interaction Interface» have been developed as a mobile application. In addition, system includes geographic information system that allows visualizing, analyzing and predicting the state of the object. Thematic maps of spatial pollution of the Taganrog Bay at control points were simulated. The main features of the system are shown and recommendations for its application are offered.
