The condition of the centralized drinking water supply continues to be a serious problem in ensuring the sanitary and epidemiological well-being of the population of the Voronezh Region, as it causes a certain risk to the health of the population of the region. The paper assesses the current state of centralized drinking water supply and sanitation in the towns Anna, Liski, Boguchar, Rossosh, which are the administrative centers of four municipal districts of the Voronezh region. The problems of providing the population of the region with high-quality drinking water and the ways of solving rational water supply were considered. In addition, based on the results of chemical analysis of samples taken from the distribution network, the quality of drinking water supplied to the population of the studied towns was established. The results of the analysis showed that the population of small towns in the Voronezh region consumes drinking water that does not meet hygienic requirements. Therefore, today it is necessary to strengthen monitoring and control over the quality of drinking water supply, and the population of small towns in the region should use household water aftertreatment filters.

На одном из первых мест среди наиболее важных факторов, влияющих на состояние здоровья населения, стоит качество питьевой воды. Вода - самое распространенное, самое уникальное и удивительное вещество в природе. Среди всех веществ, присутствующих на земле, вода благодаря особым своим физическим, химическим и квантово-механическим свойствам занимает исключительное положение в природе и играет особую роль в существовании органической жизни. Вода в большинстве водных объектов оценивается как загрязненная по многим физико-химическим, биологическим и органолептическим показателям, что связано с высокой техногенной нагрузкой на окружающую природную среду. Вода из подземных водоисточников обладает природным повышенным содержанием железа, повышенной жесткостью. В связи с этим, проблема питьевого водоснабжения продолжает оставаться актуальной, а повышение надежности и качества водоснабжения населения питьевой водой является одной из первоочередных социальных проблем. Оптимизация условий водопользования и обеспечение населения достаточным количеством доброкачественной питьевой воды являются важнейшими государственными задачами. Управлением Роспотребнадзора по Воронежской области с 2014 по 2019 год, в рамках своих полномочий осуществлялись надзорные мероприятия за организацией водоснабжения населения. Особое внимание предавалось контролю качества питьевой воды ее безопасности в эпидемиологическом отношении, безвредности по химическому составу. Результаты данной работы представлены в статье Among the most important factors affecting the health of the population, one of the first places is the quality of drinking water. Water is the most common, most unique and amazing substance in nature. Among all the substances present on earth, thanks to its special physical, chemical and quantum mechanical properties, it occupies an exceptional position in nature and plays a special role in the existence of organic life. Water in most water bodies is assessed as polluted by many physicochemical, biological and organoleptic indicators, which is associated with a high man-made load on the environment. Water from underground water sources has a high natural iron content, increased rigidity. In this regard, the problem of drinking water supply continues to be relevant, and improving the reliability and quality of drinking water supply to the population is one of the priority social problems. Optimization of water use conditions and provision of the population with an adequate amount of safe drinking water are the most important state tasks. The Directorate of Rospotrebnadzor in the Voronezh Region from 2016 to 2018, within its authority, supervising the organization of water supply to the population was carried out. Particular attention was paid to the quality control of drinking water of its safety in the epidemiological respect, the safety of the chemical composition. The results of this work are presented in the article

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.
