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 Impact

Abstract In many parts of the world, drinking water storage takes place in near-house or in-house tanks. This can impact drinking water quality considerably. International and numerous national standards and guidelines addressing the construction, installation and operation of domestic drinking water storage tanks are reviewed on their consideration of water quality aspects and the minimisation of health risks associated with drinking water storage. Several national and international standards and guidelines are reviewed in terms of drinking water quality requirements. Factors that have an impact on water quality in relation to the use of domestic drinking water storage tanks are summarised comprehensively. The impact of the domestic storage of drinking water on water quality, the points and locations of use, their positioning, the materials they are made of, their design and operation, as well as aspects of how they are operated and maintained is outlined and discussed in detail. Finally, the incorporation of aspects regarding water quality in drinking water storage tanks in standards and guidelines is presented and assessed. To make the use of domestic drinking water storage tanks safer and more efficient, recommendations for modifications, improvements and extensions of respective standards are made.

The aim: A study of the impact of drinking water quality on the state of dental health in schoolchildren who permanently live in areas of biogeochemical deficiency of fluorine and iodine. Material and methods: The composition of the drinking water of the city of Uzhhorod and the city of Rakhiv has been investigated. The prevalence and intensity of dental caries in children is determined, drinking water is taken in accordance with Uzhhorod and Rakhiv. Results: The regional features of the composition of drinking water of the mountain Rakhivsky district of the Transcarpathian region are the high variety of combinations of mineral components and the frequent excess of the normative content of dry residue components, namely nitrates, sulfates, chlorides, magnesium and calcium.Water oxidation, total stiffness and total alkalinity were significantly different. The established drinking water quality indicators have a direct dependence on the prevalence and intensity of dental caries in children, that is, a significant increase in the number of carious temporary, carious and distant permanent teeth and a decrease in filled temporary and permanent teeth (p < 0. 05) were diagnosed. Conclusions: One of the most pressing problems in water hygiene is the urgent need to review and improve regulations, State sanitary regulations, standards and other regulations in the field of drinking water, including through the development of regional drinking water quality standards.

For many communities, drinking water comes from surface water sources, or source water, such as rivers and creeks. Within the city of Grants Pass, Oregon, this is the case. The Rogue River, which spans 215 miles, beginning near Crater Lake and emptying into the ocean at Gold Beach, is Grants Pass’ drinking water source. While the capacity of the Rogue River, in relation to drinking water, is rarely an issue for the City of Grants Pass’ Public Works Department, the potential contaminant sources (PCS) from the urban, commercial, and industrial geographical areas of Grants Pass is a concern. In order to deploy treatment processes that are capable of targeting these PCS, it is important to have an idea of where and how these PCS are reaching the storm drains, creeks, and eventually the Rogue River. The purpose of this study was to identify area-specific risk components and how those components spatially aligned with PCS and their locations. Geographic Information System (GIS) analysis and a risk matrix were used to rank the PCS according to risk in relation to Grants Pass’ source water intake. PCS ranked as high priority, or exuding the highest risk to drinking water quality, were followed up with onthe- ground surveys. After surveying the high priority PCS, best management practices (BMP) recommendations were made to the City of Grants Pass to better protect the drinking water quality. Branching off of this initial project work came similar studies in many other Rogue Basin communities. With this continued work, improvements were made to streamline the processes, such as recording survey observations. Overall, this project work has led to many discoveries regarding threats to drinking water quality and how to best respond to certain types of threats.

Many communities along the US-México border remain without infrastructure for water and sewage. Residents in these communities often collect and store their water in open 55-gallon drums. This study evaluated changes in drinking water quality resulting from an intervention that provided large closed water storage tanks (2,500-gallons) to individual homes lacking a piped water supply. After the intervention, many of the households did not change the source of their drinking water to the large storage tanks. Therefore, water quality results were first compared based on the source of the household's drinking water: store or vending machine, large tank, or collected from a public supply and transported by the household. Of the households that used the large storage tank as their drinking water supply, drinking water quality was generally of poorer quality. Fifty-four percent of samples collected prior to intervention had detectable levels of total coliforms, while 82% of samples were positive nine months after the intervention (p &lt; 0.05). Exploratory analyses were also carried out to measure water quality at different points between collection by water delivery trucks and delivery to the household's large storage tank. Thirty percent of the samples taken immediately after water was delivered to the home had high total coliforms (&gt;10 CFU/100 ml). Mean free chlorine levels dropped from 0.43 mg/l, where the trucks filled their tanks, to 0.20 mg/l inside the household's tank immediately after delivery. Results of this study have implications for interventions that focus on safe water treatment and storage in the home, and for guidelines regarding the level of free chlorine required in water delivered by water delivery trucks.
