The analysis of the current state of major water consumers and water complex participants is performed. The data on the increase in centralized water supply of the residential accommodation during 2000-2018 is presented. Significant decrease in the volume of water used for drinking water supply is shown. The improvement of water quality in water bodies of most regions is revealed. The use of fresh water for production needs in the Don River basin decreased from 5.8 to 2.9 km3 from 1990 to 2018. The water circulation coefficient in industry increased from 64 to 85%. The area of irrigated lands in the basin has started to decrease significantly since 1990. In 2000 every second hectare of available irrigated land was watered and in 2016 only every fourth was watered.

Švihov dam, the largest drinking water source in the Czech Republic and Central Europe, has problems with eutrophication. The Švihov dam catchment spreads over 1200 km<sup>2</sup> and supplies over 1.5 million people in the capital of Prague and the Central Bohemian region with drinking water. Due to intensive agricultural activities and a lack of wastewater treatment plants in small settlements, the water quality is deteriorating. As a result, corrective measures need to be taken. Technological Agency of the Czech Republic supported this research which proposes different scenarios for a reduction of water quality degradation in the dam. The Trnávka dam watershed was chosen for study purposes as it occupies one quarter of the Švihov dam watershed. Hydrological balance was established using measured data. Point and non-point sources of nutrients were determined by field research and included in a Soil and Water Assessment Tool (SWAT) model. This study aims to propose complex watershed management to improve the state of the environment in the entire area and to reduce eutrophication. Different management practices would reduce nutrient loads of streams and increase water quality which is the critical factor in dam eutrophication. This research brings methodology and systematic approach to integrated management, and can be applied not only for the Švihov dam, but also for other watersheds, including those which function as drinking water supply.

The Status

Prolonged persistence of toxic cadmium (Cd), chromium (Cr) and lead (Pb) in the aquatic environment are due to its nonbiodegradable characteristic. A few studies have reported higher concentrations of these metals in the transboundary Langat River, Malaysia. This study determined the spatial and temporal distributions of Cd, Cr and Pb concentrations (2005–2015) in the Langat River along with assessing the status of these metals in the drinking water supply chain at the basin. Water samples were collected once in 2015 from the drinking water supply chain, i.e., from the river, treated water at plants, taps and filtration water at households. Determined mean concentrations of Cd, Cr and Pb by inductively coupled plasma mass spectrometry in the Langat River were within the drinking water quality standard of Malaysia and the WHO, except for the Pb (9.99 ± 1.40 µg/L) concentration, which was at the maximum limit, 10 µg/L. The spatial and temporal distribution of these metals’ concentrations indicate dilution of it downstream, along with the increasing trend in rainfall and water flow, especially during the northeast monsoon. Significant correlation and regression analysis of the Cd, Cr and Pb concentrations also indicate that the sources of this metal pollution are mainly the natural weathering of minerals along with anthropogenic activities in the basin. The determined overall water quality of the Langat River is categorized Class IIA (i.e., clean), which requires conventional treatment before drinking; however, the maximum removal efficiency of these metals by the plants at the basin was about 90.17%. Therefore, the proactive leadership roles of the local authorities will be appropriate to reduce the pollution of this river as well as introducing a two-layer water filtration system at the Langat River Basin to accelerate the achievement of a sustainable drinking water supply.

Urbanization has caused limitations on water resources, while climate change has reduced amounts of surface water in some parts of the world. Kikuyu, a suburban area in Kiambu county, Kenya, is facing this challenge. The major challenge in the study is scarcity of potable water, resulting in inadequate water supply to Kikuyu residents. Currently, only 63.6% of the population is being supplied with water by Kikuyu Water Company, the company mandated to supply water to the area. Water demand was 2972 m3/day in 2015 and was projected to be 3834 m3/day by 2025. This has put pressure on the already exploited clean water resources, making it necessary to seek additional sources of domestic water. Storage capacity and water quality of surface water bodies, especially small reservoirs whose water can be used to ease the demand, need to be assessed for supplemental water supply. This study aimed at assessing the suitability of the abandoned quarry reservoir as a source of potable urban water by determining its storage capacity characteristics and water quality status. Volume characteristics were determined using bathymetry survey in January 2019. Water samples were collected in January and August 2019 and analyzed for chemical, physical, and bacteriological quality, as per the American Public Health Association (APHA) standard methods for water and wastewater. Parameters were evaluated based on World Health Organization (WHO) and Kenya Bureau of Standards (KEBS) guidelines for drinking water, and rated based on the drinking water quality index (WQI). The reservoir’s maximum storage capacity was found to be 128,385 m3, the surface area was 17,699 m2, and the maximum depth was 15.11 m. Nineteen of the twenty-five investigated parameters were within the acceptable standards. However, the concentrations of manganese (Mn), cadmium (Cd), iron (Fe), turbidity, total coliforms, and Escherichia coli (E. coli) were above the acceptable limits. Manganese and iron levels increased with depth. The overall WQI of the reservoir was 82.51 and 85.85 in January and August, respectively. Therefore, based on WQI rating, the water scored a good quality rating and could be used for domestic supply upon treatment. The original achievement of this study is establishment of the volume of the water in the quarry as an additional source of water to the nearby community, along with water quality status.

This paper articulates the complexities of adaptively managing Delaware River water resources to meet shifting priorities of drinking water supply, drought mitigation and flood mitigation, as well as conflicting stakeholder interests. In particular, the paper examines the short-term and long-term programs that comprise the Delaware River Basin Commission's (DRBC) and the 1954 US Supreme Court Decree parties' successful adaptive management approach that seeks to balance the growing list of demands for water resources management, including drinking water supply, drought management, flood control and cold water fisheries protection. Review of the DRBC's adaptive governance approach reveals the critical complexities of designing experimental, yet science-driven management approaches and effectively engaging various sets of stakeholders in the associated decision-making processes.

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
