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.

Summary. Introduction: In order to conduct a more precise and objective assessment of drinking water quality in the centralized cold water supply systems, it is essential to increase the coverage of population with laboratory control. It is therefore expedient to consider the possibility of using production control data collected within the drinking water quality monitoring system and including them in statistical reporting forms of Rospotrebnadzor for subsequent accounting when assessing the implementation of the Russian Federal Clean Water Project within the National Ecology Project. Our objective was to substantiate requirements for organization of production control of drinking water with considering a further use of its results in assessing drinking water quality. The materials of the research included current regulations and literature data. We applied methods of sanitary and epidemiologic expert examination, assessment and survey as well as methods of systemic and content analysis. Results: To evaluate the supply of the population with high-quality drinking water, it is important to consider not only test results collected within the framework of the federal state sanitary and epidemiologic surveillance but also the results of production control carried out by legal entities and individual entrepreneurs operating centralized cold water supply systems. However, organization of production control and the use of its results is usually associated with such problems as the choice of the most representative sampling points, identification of a sufficient list of controlled indicators, quality of results, etc. Conclusions: Before including the results of drinking water quality production control in the drinking water quality monitoring system, it is necessary to set the requirements for selecting monitoring sites, analytes, frequency of testing, etc. To legitimize the use of production control results, it is important to develop regulations that oblige organizations carrying out production control of drinking water quality to submit their results to Rospotrebnadzor bodies and institutions for their use in comprehensive drinking water quality assessments.

Vulnerability of drinking water supply systems (DWSSs) depends on different factors such as failures, loss of security, man-made threats, and the change and deterioration of supply-water quality. Currently, the lifespan of several DWSSs worldwide has been exceeded, exasperating these issues. The monitoring activity and the transparency of information on water availability and quality are becoming increasingly important in accordance with the national regulations and standards, and with guidelines of the World Health Organization (WHO). These activities can be considered as support and guidance tools for identifying health-related risks, for building a safe management of drinking water supply systems, and for improved user confidence in the consumption of tap water. In this context, in the present work an analysis of the quality monitoring data of DWSSs was carried out using multivariate techniques. The analysis considered several chemical–physical parameters collected in the period 2013–2020 for some DWSSs in the Emilia-Romagna region, Italy. Principal component analysis (PCA) and cluster analysis (CA) methods were used to process and reduce the dimensionality of the data, to highlight the parameters that have the greatest influence on the qualitative state of the supplied water and to identify clusters.

The study presents an analysis of water quality monitoring in terms of the content of heavy metals, which is conducted in three independent water supply systems in Poland. The analysis showed that the monitoring of heavy metals isn't reliable - both the quantity of tested water samples and the location of the monitoring points are the problem. The analysis of changes in water quality from raw water to tap water was possible only for one of the analysed systems and indicate a gradual deterioration of water quality, although still within acceptable limits of legal regulations.
