The paper demonstrates statistical analysis results of biocontamination of Simferopol water reservoirs of centralized drinking water supply sources. The biocontamination results were obtained by permanganate oxidizability factor. The analysis revealed a consistent patt ern of biocontamination distribution and its analytical description for four sources of centralized water supply. The paper also introduces models of this factor distribution for water purifi ed in water-purifi cation plants of the city of Simferopol (in clean-water reservoirs). The eff ectiveness of two-step water purifi cation scheme (horizontalstrainer chamber - high-rate trickling fi lter) from biocontamination is calculated. The research demonstrates a probability of exceeding permanganate oxidizability normative values for drinking water according to WHO and EU standards and according to drinking water requirements for this indicator in the Russian Federation. The required degree of permanganate oxidizability disposal at water treatment plants which will make the quality of drinking water meet WHO and EU standards is also defi ned.

According to UN estimates, the shortage of safe drinking water can become one of the most acute and pressing problems. The specificity of this problem for Russia is not a shortage of water resources, but their pollution and ongoing degradation of water bodies. The quality of water is understood as the totality of its properties associated with the nature and concentration of impurities in the water. Water analysis is the only tool for monitoring its condition and properties. During the experiment, a team of researchers took samples of drinking water from the water supply network in various districts of the Norilsk industrial region, studied the dependence of the quality characteristics of water on the location and sampling method. Based on the findings, conclusions on the quality of drinking water were drawn. During the experiment, the authors found that in terms of organoleptic indicators, drinking water in all areas of the NIR meets the requirements of Sanitary Rules and Regulations and GOST. Taking samples at three control points of the Norilsk industrial region, it has been proven that the water is soft and its salt content is mainly due to the presence of hardness salts. Having made the necessary analyses, the authors found that the presence of microorganisms in the water supply network of the NIR is not significant, the permanganate oxidisability indicator does not exceed the requirements of Sanitary Rules and Regulations.

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

Grading Scale

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.

Lower Volga

Волга почти на всем протяжении от Твери до Астрахани является истощенным водоемом по качественному составу. По Нижневолжскому бассейну ресурс экологически чистой воды составляет не более 3% общих ресурсов поверхностных вод Астраханской области. В связи с этим в Астраханской области проблемы качества питьевой воды обусловлены загрязнением природной воды, неудовлетворительной очисткой ее на водопроводных станциях, вторичным загрязнением в разводящих сетях. Проведен анализ экологического состояния Нижней Волги, а также оценка его влияния на качество питьевого водоснабжения. Применяемые в Астраханской области технологии очистки воды для водоснабжения запроектированы и построены в 1960–70-е годы и не рассчитаны на грязевую нагрузку по качеству и количеству, значительно отличающуюся от современной ситуации. Проведен анализ работы водозаборных и водопроводных очистных сооружений, который показал, что они находятся в крайне неудовлетворительном техническом состоянии и морально устарели. Предложены пути решения вопросов по улучшению качества питьевого водоснабжения с учетом сложившейся кризисной экологической обстановки на Нижней Волге и мирового опыта. Almost along the entire length from Tver to Astrakhan, the Volga River has been a depleted water reservoir in terms of its qualitative composition. In the Lower Volga basin the resource of ecologically clean water is less than 3% of the total surface water resources of the Astrakhan Region. In this regard, drinking water quality problems in the Astrakhan Region have been caused by natural water pollution, poor water treatment at the waterworks, secondary pollution in the distribution networks. The ecological state of the Lower Volga has been analyzed, and its impact on the quality of drinking water supply has been estimated. The technologies of water purification used in the Astrakhan Region for water supply were designed and implemented in the 1960s–70s; they were not designed for the pollution load in terms of the quality and quantity significantly different from the current situation. An analysis of the operation of water intake and water treatment facilities was carried out that showed their extremely unsatisfactory technical condition and obsolescence. The ways of solving the problems of improving the quality of drinking water supply with account of the current critical ecological situation in the Lower Volga Region and world experience, are proposed.

Hygienic Standard

The purpose of the study was to monitor the quality of drinking water supply in Samara. The quality of drinking water was evaluated in 7 districts of Samara on the basis of 20 sanitary-chemical indicators in accordance with health and safety norms and regulations (SanPiN 2.1.4.107401 20102013 and 20182019). A changed color of drinking water was mainly observed in the areas with water supply from the Saratov reservoir (53,5 8,5% of samples). In the areas with underground water sources the dry residue and hardness of drinking water exceeded hygiene requirements by 100% and 87,5% of samples respectively. 64% of samples in 20102013 and 17,4% of samples in 20182019 were non-standard in terms of permanganate oxidation. Several samples didnt meet the hygienic standard for iron content. Adverse changes in the temporal dynamics of the proportion of samples that didnt meet the hygienic standard for the content of oil products were noted. The quality of some samples of drinking water in Samara did not meet sanitary requirements for some indicators. No significant differences were found between the average long-term values of sanitary and hygienic indicators for urban areas and the obtained data for drinking water in the new housing estate, which suggests that the condition of the water supply pipes doesnt influence the composition of the drinking water in the yard or at home.
