Water is an essential resource for life on earth and is the source of several microbiological and toxicological diseases. The Aguégués one of the communes of the lower valley of Ouémé-Benin are very exposed to these type of diseases. Pathogens swarm in a highly polluted environment because of the peculiarity of this predominantly aquatic area. This is what justifies this research, which aims to assess the quality of drinking water for the populations of the Commune des Aguégués. The research technique focused on the field survey which made it possible to identify the different sources of water supply used by the population. Likewise, the physico-chemical and bacteriological quality of these water sources has been determined. These research techniques have made it possible to discover that the population of Aguégués uses several sources of water. Apart from the recommended sources (National Water Company of Benin and Village Water Supply) the populations use other sources of water. These are rainwater consumed in the rainy season by 97% of the households surveyed, surface water used by 78.26% of the population, especially during flood periods for various uses. Physico-chemical and bacteriological analyzes have shown that apart from SONEB waters only available in the districts of Zoungamey and Houédomey, the other sources of water have parameters which do not comply with WHO standards. This justifies the prevalence of diarrheal diseases in the study environment, which represents the second cause of consultation in health centers.

In Morocco, the quality of water gathered in dams is deteriorating considerably due to different sources of pollution. One of the consequences of this situation is the presence of nutrients , particularly phosphorus and nitrogen, in the water. This, however, indicates an advanced state of eutrophisation of waters. This phenomenon causes an imbalance in the ecosystem with an anarchic development of seaweeds and an intense consumption of oxygen at the bottom of lakes. The present study aims to present the results of the optimization of the choice of the pumping area of the waters of the BAB LOUTA dam in TAZA region, Morocco. This dam is the dam that provides the city of TAZA with drinking water. The results of physico-chemical analyses (dissolved Oxygen, Turbidity, Manganese, pH, and the temperature) were taken according to a vertical deep profile for a duration that spreads from March 2016 to March 2017.

Water supply companies in the UK have a duty under prime UK legislation to notify the Drinking Water Inspectorate of events affecting or potentially affecting the quality of drinking-water supplies. Under the same legislation, the Inspectorate has a duty to investigate each event. After assessing all of the information available, including companies' reports, the Inspectorate advises on the way in which the event was handled and whether any statutory requirements were contravened. If appropriate, a prosecution of the water company may be initiated. Copies of the assessment are sent to the water company, relevant local and health authorities, Ofwat (the economic regulator), the regional Consumer Council for Water and any other interested parties, including consumers who request it. Generic guidance may be issued to the industry on matters of wider concern. This paper considers the role of the Inspectorate, the powers available to it and reporting arrangements. An overview is presented of events that occurred between 1990 and 2005 and common features are identified. Causes of different types of event are discussed. The importance of well-established contacts between the various interested parties involved in protecting public health is emphasised through discussion of example incidents.

Качество услуг водоснабжения и водоотведения за первые двадцать лет XXI века вывело на новый уровень развития ГУП «Водоканал Санкт-Петербурга» благодаря внедрению инновационных технологий в системах водоснабжения и водоотведения. Использование технологий, таких как двухступенчатое обеззараживание питьевой воды, дезодорирование полигонов, геотубирование, применение центрифуг «Флоттвег», порошкообразного однокомпонентного флокулянта, порошкообразного активированного угля, внедрение системы измерения осадков, осуществлялись при активном участии Федора Ивановича Лобанова – помощника генерального директора ГУП «Водоканал Санкт-Петербурга» по работе с промышленностью, которому в ноябре 2021 г. исполнилось 80 лет. The quality of water supply and wastewater disposal services over the first twenty years of the 21st century has brought SUE «Vodokanal of St. Petersburg» to a new level of development owing to the introduction of innovative technologies in water supply and wastewater disposal systems. The use of technologies, such as two-stage disinfection of drinking water, odor control of landfills, geotubing, the use of Flottweg centrifuges, powdered one-component flocculant, powdered activated carbon, the introduction of a precipitation measurement system, were carried out with the active participation of Fedor Ivanovich Lobanov, Assistant to the General Director of SUE «Vodokanal of St. Petersburg» on dealing with industries, who turned 80 in November 2021.

Aim. Study of the influence of drinking water quality on the ecologically-dependent morbidity of the population of the Republic of Dagestan.Material and Methods. Methods of current and retrospective analysis of regional health indicators and methods of mathematical-statistical and medical-geographical analysis were used. Statistical processing of the results was carried out using the STATISTICA and Excel software packages. When carrying out laboratory studies on the quality of drinking water, we used a Lumex atomic absorption spectrometer "MGA-915MD".Results. Numerous hygiene studies indicate the direct impact of unsatisfactory drinking water quality on the health of a population. The relationship between sanitary and chemical indicators and the incidence rate for a number of nosological forms has been proven. It is generally accepted that human health is influenced by lifestyle factors (working, living and relaxation conditions), heredity and the ecological condition of the area of residence, including the quality of drinking water. Although it is not possible to differentiate the share of the negative effect caused by the consumption of poor quality drinking water but the incidence of certain nosological forms (cancer of the esophagus, gastrointestinal tract and kidney diseases) in the those regions of the Republic of Dagestan under consideration correlates with the characteristics of drinking water.Conclusion. The problem of pollution of water supply sources for the population in the dynamics of the long-term remains a priority concern. The quality and safety of drinking water are decreasing, which cannot but have a negative impact on public health. Correlation linkages between indicators of drinking water quality and oncological morbidity of the population were also established in indicators below the maximum permissible concentrations, which corresponds to a typical logistic model of causal relationships and serves as evidence of the high dependence of health disorders on chemical contamination of water supply sources.
