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.

Changes in the land use and land cover in areas adjacent to water reservoirs directly affect the quality of this water. This research presents a study on the water quality in the basin of one of the most important public water supply reservoirs in the city of Juiz de Fora, Minas Gerais. The main objective of this study was to analyze the behavior of limnological parameters and the correlation with land use and land cover in the contribution basin of the Doutor João Penido reservoir (CBJPR). The methodology was based on the analysis of water quality parameters, related to water samples collected from 2012 to 2015. Six sampling points were chosen from different locations: spring, medium course, main tributaries of the reservoir and the reservoir catchment. The parameters analyzed were turbidity, total solids (TS), oxygen consumed (OC), dissolved oxygen (DO), electrical conductivity, total nitrogen (TN), total phosphorus (TP), E. Coli, temperature, pH and total dissolved solids (TDS). The Kendall’s tau test was used to analyze the correlations between the parameters of water quality, land use and land cover in the CBJPR. In general, measured parameters showed better results in spring and in reservoir catchment, showing a worse quality of the water along the tributaries and the dilution power of the reservoir. The correlations pointed to the need for protection and preservation of forests in strategic locations to ensure good water quality.

Clean water is a basic necessity for daily life. Clean water helps people maintain their daily lives in case of domestic activities. If using unclean water, it will be harmful to the health because water is the medium that transports chemicals and bacteria, viruses, parasites causing diseases that are not visible to the naked eyes. According to statistics, Our country still has many places where the quality of water supply is not ensured for daily life, especially in mountainous, frontier areas and places where the terrain is difficult and lacks of facilities. The water used for living in the northwestern region in general and the Ta Vai stream’s basin in Ha Giang province in particular is taken from rivers and streams that have not been treated or have been processed but the water quality is not guaranteed for living. Therefore, a study on the construction of the treatment model of Ta Vai spring water in Ha Giang province by using membrane technology combined with integrated filter materials for water supply is essential. The research shows that the water treatment model in Ta Vai stream by using membrane technology combined with integrated filter materials has completely treated water as reaching the quality of QCVN 02: 2009 / BYT - National technical regulation on domestic water quality.

Purpose. Assess the quality of drinking water of sources of decentralized water supply of rural settlements of Berezivka united territorial community of the enlarged Zhytomyr district. Methods. Field, laboratory-analytical, statistical. Results. As a result of research it is established that the greatest contribution to the pollution of drinking water is made by nitrates, the excess content of which was recorded on average in 50.7% of the selected samples, and in 57% of the studied settlements water belongs to quality class 4, "Limited" given undesirable quality. A critical situation was recorded in Bolyarka, Bondartsi, Dubovets and Cheremoshne villages, in which well water had increased content of nitrates in all selected samples. On average, 34% of the selected water samples do not meet the standard for the pH value in the direction of its reduction. In terms of pH, quality classes vary from "excellent", very clean to "good", clean water with a bias to the class of "satisfactory", slightly contaminated acceptable quality). The total iron content exceeded the standard by 6.6% of the selected samples. Conclusion. It is proved that the formation of the general class of water quality is significantly influenced by a group of general sanitary indicators, which is primarily due to the high content of nitrates in the studied sources of decentralized water supply. The calculation of the integrated ecological index of development of rural settlements according to the indicators of drinking water quality showed that such rural settlements as: Zamozhne and Sadky need priority attention; 11 settlements need improvement; only village of Vasylivka needs support at the same level.
