Providing population with drinking water conforming to all hygienic standards is a pressing issue on territories where oil fields are located. In our research we focus on assessing water supply sources located in areas with oil fields and health risks for people who consume water from centralized water supply systems aimed at providing drinking water and water for communal use. Our research goal was to hygienically assess health risks for people living in areas where oil fields were located in Bashkortostan; these health risks were caused by people consuming water from centralized water supply systems. Our analysis was based on data obtained via laboratory research performed by «Bashkommunvodokanal» water supply facility and Bashkortostan Center for Hygiene and Epidemiology; the data were collected in 2016–2018 in Chishminskiy and Dablekanovskiy districts. Risks associated with drinking water quality were assessed taking into account all the requirements fixed in the Guide R 2.1.10.1920-04. Organoleptic risks related to water olfactory-reflex properties were assessed according to procedures fixed in the Methodical Guidelines MR 2.1.4.0032-11. Overall carcinogenic health risk assessed in Chishminskiy and Davlekanovskiy districts was higher than maximum permissible level due to chromium6+, DDT, lindane and arsenic detected in drinking water. Population carcinogenic risks amounted to 7 additional cases for people who consumed water supplied via water intake in Alkino-2 settlement; 69 additional cases, Isaakovskiy water intake; 76 additional cases, Kirzavodskoy water intake. Results obtained via non-carcinogenic risk assessment performed for all examined territories indicate that diseases might occur in the hormonal system (HQ =3.04–4.56), liver (HQ =2.3–3.83), and kidneys (HQ =1.47–2.45). The highest non-carcinogenic risks were detected for people who took water from Kirzavodskoy water intake in Davlekanovskiy district. We also detected unacceptable organoleptic risk (higher than 0.1) caused by excessive water hardness in Chishminskiy district. All the obtained results call for developing and implementing a set of activities aimed at reducing health risks for population.

Abstract Objectives Pharmaceuticals are emerging contaminants in the environment. Little has been published about the presence of pharmaceuticals in waterbodies nearby or on reserve land of First Nations in Canada. The objectives of this study were to (1) quantify the level of pharmaceuticals in First Nations’ surface waters, (2) calculate the human health risks of the mixtures found, and (3) measure the exposure to pharmaceuticals in First Nations’ drinking water where source water was highly contaminated. Methods This participatory study measured the levels of 43 pharmaceuticals from surface water samples taken at three water sampling sites chosen by the 95 participating First Nations. The sites were in proximity to recreational areas, fishing areas, drinking water sources, and/or wastewater outflows. When elevated levels of pharmaceutical mixtures were found in samples, drinking water samples were obtained and analyzed for potential pharmaceuticals. Human health risks were calculated by an established protocol. Results In total, 432 samples were collected at 302 water sampling sites (285 surface water, 11 drinking water, and 6 wastewater sites). Quantifiable levels of 35 pharmaceuticals were found in 79 of the 95 (83%) participating First Nations at 193 of the 285 surface water sites (68%). Overall, the levels found were comparable to or lower than those found in other studies in Canada and worldwide. Conclusion In almost all participating First Nations, there is no human health risk from consuming surface water for drinking. However, surface water in the vicinity of major urban centres should not be used as secondary untreated water sources due to the elevated human health risk associated with exposure to the mixtures of multiple pharmaceuticals detected.

The object of the study was the centralized drinking water supply system of the Voronezh Region. The purpose of the study was to assess health risks for the population of the Voronezh Region associated with drinking water quality. Materials and methods: The data of the regional drinking water quality monitoring system, which included monthly sampling and testing of water samples at 553 sites in 32 administrative districts and the city of Voronezh for 8 priority sanitary and chemical indicators (total hardness, concentrations of iron, manganese, nitrates, nitrites, boron, fluorine, and ammonium ions) for the years 2010-2019 were used. To achieve the objective based on monitoring studies of drinking water quality in the water distribution system, four generally accepted stages of risk assessment were implemented including hazard identification, evaluation of dose-response relationship, exposure assessment, risk quantification and characterization. When evaluating the exposure, four calculation scenarios were considered and probable body burdens for children and adults were calculated using the average long-term concentration and 95 percentile of concentration in a separate administrative territory. Results: Regional non-carcinogenic risks estimated on the basis of the average regional concentrations of priority pollutants did not exceed acceptable values (HQ < 1) for 6 of 7 ingredients. Unacceptable risk levels were observed in two of 33 administrative districts due to the presence of nitrates in drinking water (HQ ranged 1.34 to 2.95 for children and equaled 1.26 for adults). Detailed information for separate settlements (control points) using an aggravated scenario helped identify 4 rural settlements in 2 administrative districts with unacceptable risks for the child population of iron in drinking water (HQ up to 2.31), 230 settlements in 27 districts – of nitrates (HQ up to 9.51), one settlement – of boron (HQ = 1.17), and 35 settlements in 13 districts – of fluorine (HQ up to 4.17). Discussion: Summarizing the results of the regional studies of health risks for the population associated with the quality of drinking water, one can testify the shift of the problem to rural settlements where water treatment is practically null. The use of average concentrations of chemicals in drinking water in administrative districts proved to be insufficiently objective and having significant uncertainties. The reduction of uncertainties was achieved by a detailed review of the information for each monitoring site and the use of the 95th percentile concentration of the chemical to assess the health risks for children and adults. Conclusions: With a sufficient degree of certainty, the priority regional indicators determining the unacceptable level of non-carcinogenic risk (HQ > 1) associated with the quality of drinking water include elevated levels of nitrates, fluorine, boron, and iron. Key words: drinking water, centralized water supply, water quality, public health risk.
