Aim. Study of the influence of drinking water quality on the ecologically-dependent morbidity of the population of the Republic of Dagestan.Material and Methods. Methods of current and retrospective analysis of regional health indicators and methods of mathematical-statistical and medical-geographical analysis were used. Statistical processing of the results was carried out using the STATISTICA and Excel software packages. When carrying out laboratory studies on the quality of drinking water, we used a Lumex atomic absorption spectrometer "MGA-915MD".Results. Numerous hygiene studies indicate the direct impact of unsatisfactory drinking water quality on the health of a population. The relationship between sanitary and chemical indicators and the incidence rate for a number of nosological forms has been proven. It is generally accepted that human health is influenced by lifestyle factors (working, living and relaxation conditions), heredity and the ecological condition of the area of residence, including the quality of drinking water. Although it is not possible to differentiate the share of the negative effect caused by the consumption of poor quality drinking water but the incidence of certain nosological forms (cancer of the esophagus, gastrointestinal tract and kidney diseases) in the those regions of the Republic of Dagestan under consideration correlates with the characteristics of drinking water.Conclusion. The problem of pollution of water supply sources for the population in the dynamics of the long-term remains a priority concern. The quality and safety of drinking water are decreasing, which cannot but have a negative impact on public health. Correlation linkages between indicators of drinking water quality and oncological morbidity of the population were also established in indicators below the maximum permissible concentrations, which corresponds to a typical logistic model of causal relationships and serves as evidence of the high dependence of health disorders on chemical contamination of water supply sources.

Safe source of drinking water is always considered as an essential factor in water supply for cities and urban areas. As a part of this issue, drinking water quality is monitored via a useful scheme: developing drinking water quality index DWQI. DWQI is preferably used as it summarizes the whole physicochemical and bacteriological properties of a drinking water sample into a single and simple term. In this study, an evaluation was made for three drinking water treatment plants DWTPs named: Efraz 1, Efraz 2 and Efraz 3 that supply drinking water to Erbil City. The assessment was made by testing thirteen physicochemical and two bacteriological parameters during a long period of (2003 – 2017). It has been found that turbidity, electrical conductivity EC, total alkalinity, total hardness, total coliform and fecal coliform have more influence on drinking water quality. DWQI results showed that the quality of drinking water supplied by the three DWTPs in Erbil City fallen within good level. Except various occasional periods where the quality was varying from good to fair. The quality of the drinking water supply never reached the level of marginal or poor over the time investigated. The applied hierarchical clustering analysis HCA classifies the drinking water dataset into three major clusters, reflecting diverse sources of the physicochemical and bacteriological parameter: natural, agriculture and urban discharges.

Qualitative composition of the drinking water from underground sources of the decentralized water-supply of the Polissya region with intensive agriculture has been analysed. The sanitary inspection of water sources was conducted. Monitoring of underwaters quality testifies the admissible content of chlorides which are within the normative limits, but fluorides are considerably less than physiological requirements. High level of iron was registered in all studied districts but the nitrate-ion is in Naroditscky and Popylyansky districts. In Naroditscky and Ovrutsky districts the quality of drinking water may be characterized as moderately polluted. Advices on the improvement of the drinking water quality are proposed.

Introduction. Regulation of drinking water quality is a very important area of health care and improving the quality of life of the population of the Russian Federation.The aim of this work is the development a model for the assessment of the drinking water quality and calculating the share of the population, including urban, provided with high-quality drinking water from centralized water supply systems, taking into account new methodological approaches to the evaluation of the quality of drinking water using the example of water supply to settlements in the Leningrad Region. Material and methods. The data on the organization of centralized cold water supply systems and monitoring systems for drinking water quality and the results of laboratory studies of drinking water quality in the cities of Volkhov, Svetogorsk, Slantsy, Tosno were studied. Statistical processing of the results was performed, the categories of quality of drinking water supplied to the population were determined, the number of the population provided with high-quality drinking water from the water supply system was calculated in accordance with Guidelines 2.1.4.0143-19.Results. In 2018, 100% of the population was provided with quality drinking water only in the city of Slantsy. In the city of Tosno, this index reached of 83.5%. In the cities of Volkhov and Svetogorsk, drinking water was rated as low-quality. But it is worth noting that in the cities of Volkhov and Slantsy laboratory tests were carried out at 2 points, in the city of Svetogorsk - only at the 1 point, which, given the number of residents, is not enough. For an objective assessment of the state of drinking water and the development of measures aimed at improving its quality, it is necessary to increase the number of monitoring points, as well as to include the results of control and supervision measures and production laboratory control conducted by water supply organizations in the volume of laboratory information.Conclusion. The proposed model allows us to assess the drinking water quality in centralized water supply systems and the proportion of the population, including urban, provided with quality drinking water at the level of the water supply system, settlement, municipal district (urban district), subject of the Russian Federation

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.

— Over the last decade, Dhaka city of Bangladesh has experienced significant changes throughout its landscape and an extreme growth in population. As a result of environmental, economic, or demographic crises, Pressure increase on housing due to rapid urbanization and rural urban migration causes growth of slums and squatter settlements. Slums are residential areas of very high population density, high room density and poor housing with inadequate access to basic civic amenities. The specific objectives of the study are to explore the to investigate the existing water supply facilities and to know the drinking water quality of selected slums in Dhaka city. Korail slum and Geneva Camp slum have been randomly selected. Overall environment of the slum areas is disappointing due to unplanned housing, drains, roads and different authorized & unauthorized shops. The chemical quality of drinking water is satisfactory but microbiological quality of water is not up to the standard of drinking water. Due to the involvements of the Government, DWASA, and other national and international Non-Government Organization (NGO) s, the slums are getting access to pure drinking water supply although these are still insufficient.

Introduction. Social and hygienic monitoring results are currently used to assess drinking water quality in centralized cold water supply systems and calculate the number of people provided with high-quality drinking water. Additionally, they use the results of investigations against resource-supplying organizations. There is not enough information to analyze and obtain reliable data. It is necessary to develop a comprehensive solution. The complex should include combining the goals of many fragmented digital solutions that regulate collecting and analyzing large amounts of data. Materials and methods. Research materials and methods include production control programs and the results of a study of the quality of drinking water in centralized water supply systems. The object of the study is the localities of 15 subjects of the Russian Federation. Methods of system and content analysis were used for the examination. Results. As part of the production control, resource-supplying management of gathering information on the water quality of centralized cold water supply systems. The requirements for the management of state data are set out in the documents of the Analytical Center under the Government of the Russian Federation. The fragmentation of the collected data does not allow us to meet the requirements for the quality of information. To assess the water quality of centralized cold water supply systems, information about water supply sources, water pipes, control points in the distribution network, and research results can be supplemented with information from the automated information system “Housing and Utilities Reform”. The entire set of information should be transmitted to the formation system “Interactive map of drinking water quality control in the Russian Federation”. Conclusion. To obtain a set of reliable information, it is necessary to include the results of production control in the drinking water quality monitoring system, provide the standardization of formats for the presentation of laboratory research results, create a single software product and introduce changes in regulatory documents that oblige resource-supplying organizations to send the results of industrial water quality control in electronic form.

The quality of ground water for drinking water needs is based on physical, chemical and biological parameters of Romang Polong. The researcher took 5 kinds of water as samples based on land use by applying the Storet method. The water sample was tested in the field and analyzed in the laboratory. The results obtained are compared with the specified based on criteria of water quality which indicated that groundwater in the Romang Polong is suitable to be used as drinking water quality standards at the point 2, 3, and 4. However, at the point 1 and 5 are not feasible to be used as drinking water quality standards. But, it is still feasible to use for household needs such as bathing and washing. It might be happened because the physical, chemical, and biological parameters exceeded the maximum permissible threshold based on the drinking water quality standard according to Minister of Health of the Republic of Indonesia No. 492 / MENKES / PER / IV / 2010.

Summary. Introduction: Drinking water is one of the most important environmental factors sustaining life and determining human health. The goal of the Russian Federal Clean Water Project is to improve drinking water quality through upgrading of water treatment and supply systems using advanced technologies, including those developed by the military-industrial complex. The most informative and reliable sources of information for assessing drinking water quality are the results of systematic laboratory testing obtained within the framework of socio-hygienic monitoring (SGM) and production control carried out by water supply organizations. The objective of our study was to formulate approaches to organizing quality monitoring programs for centralized cold water supply systems. Materials and methods: We reviewed programs and results of drinking water quality laboratory tests performed by Rospotrebnadzor bodies and institutions within the framework of SGM in 2017–2018. Results: We established that drinking water quality monitoring in the constituent entities of the Russian Federation differs significantly in the number of monitoring points (566 in the Krasnoyarsk Krai vs 10 in Sevastopol) and measured indicators, especially sanitary and chemical ones (53 inorganic and organic substances in the Kemerovo Region vs one indicator in the Amur Region). Discussion: For a more complete and objective assessment of drinking water quality in centralized cold water supply systems, monitoring points should be organized at all stages of water supply with account for the coverage of the maximum number of people supplied with water from a particular network. Thus, the number of points in the distribution network should depend, inter alia, on the size of population served. In urban settlements with up to 10,000 inhabitants, for example, at least 4 points should be organized while in the cities with more than 3,000,000 inhabitants at least 80 points are necessary. We developed minimum mandatory lists of indicators and approaches to selecting priority indices to be monitored at all stages of drinking water supply.
