Hakalo O. Influence of water quality on social subsystem indicators of agrosphere of Rivne region.

The subject of the research – is the quality of drinking water from different sources of water-supply, pollutants. The aim – is finding out of factors which comes the water quality in administrative districts of the region; the evaluation of influence of water quality on the social subsystem of agrosphere of Rivne region; finding out the risks which appear at the water providing of the population from different sources of water-supply. Methods: theoretical, experimental, mathematical, chemical. Scientific novelty – firstly the developing of methods of evaluation of risks which appears at the water providing of the population from centralized and decentralized sources; the evaluation of conditions of formation of the drinking waters quality at the territory of Rivne region under the influence of natural factors and factors of human’s activity. It was done the districts separation of the regional territory according to the levels of risks which appears at the water providing of the population and it was found out the dependence between drinking water and population incidence. It was done the improving monitoring of the quality of drinking water with consideration of special features of its formation at the territory of region and substantiation of recommendations of decreasing of risk level which appears at the water providing of the population of agrosphere of Rivne region. It was proposed the algorithm of calculation of index of risk level at the water providing of the population and district separation of the territory of Rivne region according to the level of risks which appear at the water providing of the population it was elaborated the map-shemes which characterize the water quality from different sources of centralized and decentralized sources of water-supply according to administrative districts of the region. Region – agriculture, ecology.
