Целью работы явилось обоснование необходимости организации и проведения на конкурсной основе благоустройства нецентрализованных водоисточников с использованием разработанной методики комплексной гигиенической и экологической оценки состояния нецентрализованных источников питьевого водоснабжения в условиях чрезвычайной ситуации. В работе использованы результаты многолетнего санитарно-гигиенического обследования и лабораторных исследований воды коллективных источников нецентрализованного питьевого водоснабжения. Определены следующие основные показатели для комплексной гигиенической и экологической оценки состояния нецентрализованных водоисточников: степень соответствия водоисточника установленным санитарно-гигиеническим и санитарно-техническим нормам и требованиям; соблюдение зон санитарной охраны; санитарно-просветительное, эстетическое и художественное оформление водоисточников; уровень благоустройства территории, окружающей водоисточники; качество воды водоисточников по результатам лабораторных исследований за определенный период. По каждому из пяти показателей предусмотрена оценка по 12-балльной шкале с последующим суммированием баллов с целью получения итогового результата комплексной оценки. Учитывая успешное проведение конкурса по благоустройству нецентрализованных источников водоснабжения с использованием разработанной методики комплексной гигиенической и экологической оценки состояния нецентрализованных источников питьевого водоснабжения в районе с резким дефицитом питьевой водопроводной воды, рекомендовано опыт проведения данного мероприятия распространить на другие административные территории, находящиеся в подобной ситуации. The work objective was substantiating the need to arrange and conduct, on a competitive basis, the improvement of non-centralized water sources using the developed methodology for a comprehensive hygienic and environmental estimation of the state of non-centralized sources of drinking water supply in an emergency. The work uses the results of many years of sanitary and hygienic survey and laboratory studies of water from communal sources of non-centralized drinking water supply. The following main indicators have been determined for a comprehensive hygienic and environmental estimation of the state of non-centralized water sources: the degree of compliance of the water source with the established sanitary, hygienic and sanitary technical regulations and requirements; compliance with the sanitary protection zones; the sanitary and educational, aesthetic and artistic design of water sources; the level of improvement of the territory surrounding the water sources; the water quality of the water sources according to the results of laboratory tests for a certain period. Each of the five indicators was estimated according to the 12-point grading scale with the subsequent summation of points in order to provide for the final result of a comprehensive estimation. Considering the successful holding of a competitive tender for the improvement of non-centralized water supply sources using the developed methodology for a comprehensive hygienic and environmental estimation of the state of non-centralized drinking water supply sources in an area with severe shortages of drinking tap water, extending the experience of these measures to other administrative territories in a similar situation is recommended.

AbstractThe Himalayas are the source of freshwater to about one-fourth of the world’s population. Paradoxically, water scarcity is one of the most prominent climate crises in the Himalayan region in general and its cities in particular. Rapid urbanization coupled with climate change is causing the rapid disappearance of natural springs resulting in water shortage in the urban areas. Governments are investing in new water supply projects to fulfil the demand of city residents as existing water sources are drying up. Solely focussed on establishing the physical infrastructure to supply water from source to users, and these drinking water projects have by and large failed to protect the water sources. These projects rely on the assumption of a fixed quantum and quality of the water source not taking into account the impacts of changes in climate and the activities of upstream communities on the ecosystem. For sustainability of the drinking water supply, it is necessary to have subsidiary plans that bring together the upstream water source communities (service providers), downstream communities (service users) and the local authority. Incentive paymentfor ecosystem services is a strategy to incentivize upstream non-user or low-user communities, whose role is critical in maintaining and improving the water supply and preserving the watershed area. This chapter highlights practical aspects of the design and implementation of incentive payment schemes drawing on research from three case studies from three small Himalayan towns in Nepal.

Introduction. The cause of toxicity and damaging effects of uranium and its compounds on the body lies in radioactivity of uranium isotopes and their decay products as well as their high chemical activity. In view of the above, we conducted parallel studies of specific activities and concentrations of uranium in household and drinking water supply sources. Materials and methods. We studied specific activities of uranium-234 and uranium-238 in the centralized drinking water supply sources of the Republic of Khakassia exceeding control levels in terms of specific total alpha activity (Aα) and converted them to mass concentrations of uranium. Parallel analyses of uranium concentrations in water using the luminescent method according to GOST R 54499–2011 were performed. Results. Our assessment of the radionuclide composition of centralized drinking water supply sources showed that Aα levels exceeding control levels were largely due to natural radionuclides uranium-238 (contribution up to 25%) and uranium-234 (contribution up to 69%). Based on the specific activities of uranium-234 and uranium-238, we estimated masses (concentrations) of uranium in water ranging from 0.007 to 0.06 mg/L depending on the water source. In the parallel tests of water samples according to GOST R 54499–2011, uranium concentrations ranged from 0.007 to 0.061 mg/L. Conclusions. The uranium concentrations in the republican centralized drinking water supply sources estimated on the basis of uranium-234 and uranium-238 specific activities differed from the concentrations of uranium measured by the luminescent method according to GOST R 54499–2011 within the error of the test method. In some settlements uranium concentrations in water exceeded the hygienic standard of 0.015 mg/L (GN 2.1.5.2280–07).
