Despite the fact that the Russian Federation, in general, is among the water-sufficient countries, some of its regions are experiencing water lack. One of such regions is the Republic of Crimea, where the situation with water supply is a serious problem after the water supply through the North Crimean canal has been stopped since 2014. The authors present the results of the spatial database’s development with the aggregated materials about the surface runoff and groundwater resources, the factors affecting their formation, collected in the research process. The database includes the information about the volumes of water consumption and the quality of the water used in the Crimean peninsula. The structure of the database created as a cartographic support for the assessment of water availability in the region is described. On the basis of the obtained data, a series of maps is created, which is an example of structuring the data and the possibility of their targeted use for the rapid display of such indicators, that will enable us to present the water availability of the Crimean regions in various aspects, as well as for solving other applied problems.

Pressure On Water Resources

AbstractIn arid areas, the pressure on water resources and in particular on groundwater resources is on the rise, mainly due to increasing demand and the deterioration of water quality. In this context, the present work aims to follow the annual evolution, between 2009 and 2019 of the physicochemical parameters, and to evaluate the quality of groundwater of the region of Mougheul, by determining the data of pH, TDS, conductivity and the concentrations of major ions ( Ca+2, Mg+2, Na+, K+, Cl−, HCO3−, SO4−2, NO3−) of 07 water points. The results revealed that all the levels of the physicochemical parameters do not exceed the WHO potability standards, except high values were observed at the level of well W6 which exceeds the limits recommended by the WHO (50 mg /l). The diagram of Schöeller and Berkaloff shows that the groundwater has the bicarbonate magnesium facies. The representation of the data on the Piper triangular diagram shows that W6 has the facies chlorinated and calcium sulfate and magnesium and the other water points have the facies bicarbonate calcium and magnesium. SAR values show that the groundwater of Mougheul is excellent for irrigation. The classification according to the Wilcox diagram shows that the groundwater of Mougheul in general is good quality, but the well of W6 water is suitable for irrigation and requires monitoring the evolution of salinity.

Practices of corporate social responsibility (CSR), especially in organizations providing key services, related to the supply of fuel, water and energy, are extremely important from the point of view of identifying stakeholders with the functioning of enterprises in line with the principles of a closed loop economy. The article discusses the origins and evolution of the concept of corporate social responsibility, with particular emphasis on the water supply and sewage industry. The research problem was the perception and expectations of stakeholders toward prosocial activities of PWiK Rybnik (Sewage and Water Supply Ltd. Rybnik). The hypothesis assumed in the study was that the external stakeholders of PWIK Rybnik positively assess the company’s involvement in the tasks carried out as part of corporate social responsibility, they notice the involvement in educational activities and additional initiatives of PWIK that improve the quality of life of its inhabitants. For the purpose of this study, a quantitative method was used. For the purpose of the survey, the authors’ questionnaire “Survey of customers’ opinions on the activities undertaken by PWiK Rybnik” was created. The surveys conducted confirmed the hypothesis that the external stakeholders of PWIK Rybnik positively assess the company’s involvement in the tasks performed as part of corporate social responsibility; they notice the involvement in educational activities and additional initiatives of PWIK that improve the quality of life of its inhabitants. The results of the research made it possible to formulate guidelines for the operation of water supply and sewage companies in accordance with corporate social responsibility in the light of the opinions of their stakeholders.

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.

Having access to a safe water supply is important to improve a person's quality of life. We examine the relationship between the influence of water availability on monthly household expenditures (the dependent variable) and independent variables such as household characteristics, tank size, usage instructions and post-construction guidance, including the management of water-related health risks. The sample consisted of 301 respondents who harvest rainwater in Uganda. A multiple regression analysis was used to analyse the data. The findings show that post-construction guidance and tank size were significant variables. This study suggests the need for a follow-up to improve health after the installation of water supply equipment, i.e., to provide information about water risks, foster reading norms and facilitate the availability and affordability of information sources, e.g., subsidised newspapers and information support devices (computers). Additionally, this study shows the possibility of increased savings due to reduced expenditures on water from vendors and the management of water-related health risks caused by a water shortage, e.g., dehydration. Overall, the study reveals two possible ways to advance policy and health in developing countries: (1) ensuring sufficient post-construction guidance for all water resources; and (2) ensuring a sustainable supply of adequate safe water in households.

Recent Outbreak

Zimbabwe’s urban areas are choking under the weight of over-crowdedness amidstdilapidated infrastructure that is characterised by constant service failure. The water andsewer systems of the country’s major urban centres are on the verge of collapse, thusputting millions of people in danger of consuming contaminated water, including thatfrom underground sources. Waste management and water supply problems manifestthemselves as challenges bedevilling many an urban area in the country. The quality andquantity of water supplied in Zimbabwe’s urban centres has plummeted in recent yearsand has assumed crisis proportions owing to the difficult economic situation and otherchallenges faced by the country. The situation is desperate and dire, as is evidenced by thepoor quality of delivered water, severe water rationing and the outbreak of water-bornediseases in the urban areas dotted across the country. The situation demands and dictatesthat solutions be proffered as a matter of urgency.The recent outbreak of epidemics hasbeen blamed on lack of access to safe water and poor sanitation, two crucial factors incontrolling the spread of diseases. An overly bureaucratic environment, where decisionsand processes take longer, makes life complicated for poor urban residents. Such ascenario motivated the researchers to examine the problem with a view to suggest waysand means of intervening to mitigate and resolve the problem. It emerged from thefindings that the problem is multifaceted in nature, hence a whole range of measures needto be adopted if a long-term solution is to be provided.
