HYGIENIC SUBSTANTIATION OF MANAGEMENT DECISIONS WITH THE USE OF THE INTEGRAL ASSESSMENT OF DRINKING WATER ON INDICES OF CHEMICAL HARMLESSNESS AND EPIDEMIOLOGICAL SAFETY

Abstract

Introduction. One of the key factors influencing on the quality of drinking water is the high level of water sources of the pollution, leading to the need for large-scale water treatment. There are remained risks, the consequence of which may lead to the deterioration of the quality of drinking water which is conveyed to the population. It is necessary to introduce effective technologies of water treatment, informative and reliable approaches for the assessment of epidemiological safety and harmlessness of drinking water. One of the priority directions is the development and use of methods of the integral assessment of drinking water quality. Aim of the study. For this purpose there was developed a method for the integral assessment of drinking water relying upon indices of the chemical harmlessness and a method for the comprehensive assessment of the risk of bacterial intestinal infections transmitted by water. There is proposed a method of assessing the quality of drinking water in terms of epidemiological safety, based on the fundamental principles, and providing a probabilistic approach to the assessment of health risk. Conclusion. The development, argumentation and implementation of the method of the integral assessment of the probabilistic health risk with the combined effect of chemical and microbiological agents contained in drinking water remain to be actual.
