Abstract. Introduction. The quality of drinking water in the cities of the Russian Arctic requires specific attention due to the deterioration of utilities, unprogressive water treatment technologies and environmental pollution with persistent organic pollutants and heavy metals. The purpose of the study was diseases risk assessment associated with the quality of drinking water in centralized water supply systems in the urban districts of the Russian Arctic. Materials and methods: we studied drinking water quality indicators using the data of national socio-hygienic monitoring retrospectively for the period from 2007 to 2017 in 23 urban districts of the Russian Arctic. We analyzed the indicators of epidemic and chemical composition safety. Results and discussion. Ferrum is the priority contaminant of drinking water everywhere except Kirovsk (Murmansk region). Other priority pollutants are aluminum, chloroform and manganese. High concentrations of ferrum in drinking water are coming from the deterioration of communications and its natural content in surface water sources. High concentrations of manganese are associated with its natural content in the water of underground sources. High concentrations of aluminum and chloroform are coming from impaired water treatment technology. We predict unacceptable carcinogenic risk (1,1-4,0×10–4) due to chromium, lead and arsenic in Anadyr, Arkhangelsk, Kirovsk, Labytnangi, Noyabrsk, Pevek and Providenia. We also predict unacceptable non-carcinogenic risk due to carbon tetrachloride (2,00±1,58) in Apatity and lead (0,92-2,45) in Kirovsk and Labytnangi. In most cases, positive samples for the content of microorganisms in drinking water were detected in Labytnangi, Arkhangelsk and Murmansk. Conclusions. We predict unacceptable risks associated with chromium, lead, arsenic and carbon tetrachloride in Arkhangelsk, Apatity, Kirovsk, Anadyr, Pevek, Providenia, Labytnangi and Noyabrsk. It calls for the improvement of water treatment systems and hard research of risk factors effects on health of the population.
