The Republic

In the Republic of Moldova, 57,1% of the population are live in rural areas [23]. Wells and springs in rural areas serve as the main sources of drinking water. Thus, the study carried out in the Poganesti village (Hancesti district) has shown that the main pollution sources in the locality are, especially animal and domestic waste, that have great impact under the quality of drinking water. The study has showed that 55% of the wells, as well as the surface water (small river from the locality) are polluted with nitrogen compounds. Mineralization and total water hardness of the studied wells exceed 4 -7 times sanitary standards norms and, at the same time surface water corresponds to class V of quality after hardness and nitrate concentration index.

According to a recent report by World Health Organization, the countries which still have limited access to water for drinking purposes are mainly those in the Sub-Saharan region. (Potential) water sources for drinking needs may contain different contaminants. In this context, the current study consists in an overview of the quality of surface water and groundwater in the Republic of South Africa (RSA) and Mozambique (MZ) and provides the variability ranges of the concentrations of the main pollutants in the two countries. Chemical and physical characteristics and concentrations of macropollutants, inorganic compounds (metals) and selected microorganisms were collected for surface water and groundwater and compared with the standards for drinking water set in the two countries. It was found that in surface water, microorganisms were always at very high concentrations. In addition, nickel (in RSA) and boron and chlorine (in MZ) were the most critical compounds. It emerged that in groundwater, arsenic, lead and chlorine (in RSA) and boron, sodium and chlorine (in MZ) were the main critical pollutants. Adequate treatments in the construction of new drinking water plants in rural areas should be selected on the basis of these most critical compounds and their observed variability over time.

Llobregat River

The Llobregat is a 156 km long river, which supplies 35% of the Barcelona's drinking water needs from the Sant Joan Despí Water Treatment Plant. Since the establishment of the Salt Mine Works in the Llobregat basin in 1923, a progressive salinization of the water sources has been recorded. The operation of the Brine Collector, as a public work carried out by Aigües de Barcelona (AGBAR), started in 1989; it enabled a very significant improvement in the quality of the surface water used for drinking-water production.

In the Republic of Serbia, on March 15 th , 2020 Government decided to declare a state of emergency due to the Covid-19 pandemic. One of the measures was a movement ban for people over 65 in urban areas and those over 70 in rural areas. This research should indicate how people over 65 in urban areas have endured this situation, especially in relation to the same population in rural areas, as well as implications of the movement ban on the quality of life of the elderly population. Special importance is given to the rural population engaged in agriculture. A tool of data collection in this research was anonymous survey. Respondents' answers were statistically processed, which led to clear conclusions about the large negative consequences for the elderly population, including the agricultural activities in rural areas. Covid-19 is still present, which opens further questions related to the quality of life of the elderly population, if necessity for similar measures recurs in the future.

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.

The thinly populated Balkhash District of Kazakhstan’s Almaty Region lies in the lower reaches of the Ili-Balkhash basin, which is shared by China and Kazakhstan. The district is arid and heavily dependent on inflows of surface water, which are threatened by the effects of upstream population growth, economic development, and climate change. The quality of drinking water from centralized water systems and tube wells in nine villages of the district was analyzed, and the organoleptic properties of water from these sources was also assessed by an expert and via surveys of local residents. Although most samples met governmental standards for the absence of chemical impurities, high concentrations of mineralization, chlorides, boron, iron, and/or uranium were present in some well water samples. Levels of these pollutants were as much as 4-fold higher than governmental maxima and as much as 16-fold higher than concentrations reported previously in surface water. All centralized water samples met standards for absence of microbial contamination, but total microbial counts in some well water samples exceeded standards. Organoleptic standards were met by all the water from five villages, but centralized water from one village and well water from four villages failed to meet standards based on expert judgment. Residents were, for the most part, more satisfied with centralized rather than well water, but there was no obvious relationship between the failure of water to meet standards and the locations or populations of the settlements. This is the first comprehensive assessment of groundwater used for drinking in the lower Ili-Balkhash basin, and although it relies on a limited number of samples, it nevertheless provides evidence of potentially serious groundwater contamination in the Balkhash District. It is thus imperative that additional and more detailed studies be undertaken.

Abstract Water storage tanks, fed directly from the river through opened channels, are particular systems used for water supply in rural areas in Morocco. The stored water is used as drinking water by the surrounding population without any treatment. UV-visible spectroscopy and fluorescence spectroscopy (excitation-emission matrices and synchronous fluorescence) have been tested as rapid methods to assess the quality of the water stored in the reservoirs as well as along the river feeding them. Synchronous fluorescence spectra (SFS50), collected with a difference of 50 nm between excitation and emission wavelengths, revealed a high tryptophan-like fluorescence, indicative of a pollution induced by untreated domestic and/or farm wastewater. The best correlations were obtained between the total SFS50 fluorescence and dissolved organic carbon (DOC) and biological oxygen demand, showing that the contribution of humic-like fluorescent substances cannot be neglected to rapidly assess reservoir water quality in terms of DOC by fluorescence spectroscopy.

One of the key factors for success of sustainable tourism industry in all areas, including rural, is the support of community members. The paper aims to analyze how rural residents’ perceptions of sustainable tourism development (expressed through economic, social, environmental, and physical benefits) can affect residents’ intentions to support tourism. The second aim was to determine if attachment to the particular community and perceived quality of life can have influence on attitudes towards sustainable development of tourism in rural communities. Using a sample of 881 residents living in rural areas of the Republic of Serbia, the results highlighted that perceived values of tourism were important for evaluating how tourism is developed, if it is sustainable for a community, and how it affects quality of residents’ life. The study provided better understanding of factors that can have impact on residents’ attitudes in relation to tourism and highlighted the importance of paying attention to local community as significant player for tourism development, especially in those regions that want to boost its economy by developing sustainable tourism.

In the past two decade, the Chinese government has paid a huge effort to solve the problem of drinking water in remote rural. As an alterative success case, rainwater harvesting and utility has been the most efficient way to supplying fresh water in rural areas of the Loess Plateau, a typical water resources serious shortage area in China. Focused on improving the quality of the rural village cistern water, study about the characteristics of ion release from building materials during runoff process with five representative materials used for rainwater collection: concrete, red brick, grey tile, red tile and soil was conducted. The ion releasing process and following effect on cistern water quality index, such as hardness, pH, conductivity, has been analyzed. Results revealed that the most release strength of different materials was arriving at 30s following startup. Furthermore, the test of effects of rain acidity on ion release procession showed that the total ion release increased with storm water pH declining, however, the release strength was irrelevance with runoff’s pH. Based on research results, a detailed suggestion was provided to renovate intake construction of cistern for improving the drinking water quality in remote rural areas of Weibei Semi-arid District.
