Approaches to using the risk theory to determine the degree of negative impact of drinking water supplied to the population of a large city, taking into account secondary polymetallic water pollution as it passes through water pipelines and distribution networks, are proposed. The assessment of non – carcinogenic and carcinogenic risks to the health of a sensitive group of the population-children, when metal cations are received from drinking tap water. We have proposed an approach to assess not only the immediate risk of already received ions with drinking water, but also the potential risk of high doses of metal cations in various study areas. The study areas were grouped using the cluster analysis method. For each group of zones (cluster), recommendations are provided for additional treatment of drinking water based on the results of risk assessment.

Keywords:drinking water, probability of receipt, health risk assessment, post-treatment
