The study of springs is of great scientific and practical interest, because the population increasingly prefers to use spring water as an alternative source of drinking water. Methods. Studies were conducted to determine the water quality in 14 springs located on the territory of the Republic of Tatarstan, according to physical and chemical indicators in the summer period by organoleptic, potentiometric, titrimetric, photometric and gravimetric methods. Results. It was found that the water fully meets the hygienic requirements in only 8 springs (57.1 %). It was revealed that the non-compliance of spring waters with sanitary standards for physical and chemical parameters is associated with the excess of the MAC for nitrates and hardness. Also the excess of the MAC for total alkalinity was determined. The main reasons for the poor quality of drinking water are the pollution of water sources. The data obtained confirmed the need for constant monitoring of the water quality in all springs and development of measures to improve them.

Abstract Water is a social requirement and an important factor in the ecological balance. Water from wells is good for direct consumption if the soil is not contaminated. The quality of drinking water is regulated by Law no. 458/2002 (transposing the Directive 98/83/EC on the quality of drinking water). The aim of this paper was to assess the physicochemical qualities of groundwaters from Brestea village, commune Denta, Timis County. The water samples were taken in 2015 from 10 functional wells. For the source whose physical and chemical parameters have exceeded the limit values, the monthly monitoring of the water quality (microbiological and physico-chemical properties) has been performed for 2 years. At the same time, the pH of the soil near the water sources was also measured. The results highlighted a good connection between the microorganisms from water and the nitrite, nitrate and ammonium content of water. The information can be further used to identify and eliminate the specific pollutants, areas and pollution sources.

The article presents the results of the study of the physical and chemical parameters of water for different methods of feeding the commercial young blue fox. The research was carried out at a private brewery in the Khmelnytskyi Ds. on 500 moths of the main herd. Spraying the youngsters of the experimental group was carried out in a traditional way – fom combined drinking water, distribution of water was carried out daily manually. Animals of the experimental group were injected using an automated watering system. Water samples were taken from: a water pipe, from combined drinking water for an hour and 12 hours after hand delivery – in the control group, from self-steering racks for maintenance of fur animals – in the experimental group. An analysis of the dynamics of physical and chemical parameters of water (odor, color, turbidity, rigidity, active acidity, dry residue and chlorides) was carried out for different methods of watering, and compliance with their current norms for drinking water for farm animals was established. In the course of experimental studies, there were significant differences in the organoleptic parameters and water properties in the control group as compared to water samples. Thus, for manual distribution of water for 12 hour there was a deterioration of odor on 1.1 points, increase turbidity almost twice, decrease in acidity – by 1.06 units. The indicated indicators exceeded the maximum permissible norms. The reasons for violations of the quality of drinking water in the traditional way of drinking were: contact with feed mixes in combined drillers, the effect of abiotic and biotic factors, staining residues. In samples of water in the experimental group there were no significant deviations of physical and chemical indices: they were within the limits of permissible norms. Isolation of drinking water from the environment, dosing at the need of the animal proved to be the main advantages of the atomized method of drinking fur-bearing animals, which gives grounds to recommend it for introduction into production. Further scientific research will focus on the study of the microbiological characteristics of water for different ways of drinking fur-bearing animals and, in fact, blue fox. In addition, interesting from a practical point of view can be the study of productive indicators of commodity young animals of fur animals with different methods of watering. It should take into account not only the dynamics of animal growth, the quality of fur, the level of preservation, but also production costs, including changes in the structure of the cost of fur.

Abstract The present study was carried out to assess the drinking water quality, hygiene and human health existing in the city of Jodhpur. About 89.8% of houses use household drinking water from supply, and the remaining 10.2% houses depend on public taps or other water sources. Similar results for sanitation and hygiene observed as 97% of houses did not have any garbage disposal facility and in all 10.6% did not have easy access to a sanitary facility. The results of physical and chemical parameters of ground water were above the drinking water standards, whereas in the case of household drinking water were within standard limits. The presence of total coliform, faecal coliform and faecal streptococci were showing water contamination which may be the cause of significant prevalence 5.0% (p < 0.001) of gastrointestinal infections.

Good drinking water quality is essential for the well being of all population. The object of this study was to assess the quality of drinking water in the city of Sulaimaniyah in Iraqi Kurdistan. A total of 2342 water samples from various sources providing water to the city collected during 2014 were analyzed for physiochemical and biological parameters using standard methods. Fifty percent of the samples were from, Dukan project after treatment, 26% from Dukan project before treatment, 8% from Sarchinar, 6% from city storage tanks and networks and 10% were brought by citizens from various sources.The total hardness of the city water at source after treatment was 186.3 (95% CI 179.6, 192.8), TDS was 150.6 (95% CI 149.5, 151.7), and PH was 7.74(95% CI 7.36, 8.12). The total hardness, TDS, turbidity and Calcium were considerably higher in Sarchinar than Dukan (231 vs. 161, 242 vs. 147, 2.7 vs. 1.8 and 72.9 vs. 44.5 mg/l respectively), while Sodium and Potassium were higher in Dukan than Sarchinar (3.4 vs. 1.4 and 1.4 vs. 0.08 mg/l respectively). Samples from the two supply lines from filtrated Dukan water project were compared in relation to physic-chemical characteristics and there were no significant differences in any of the parameters except PH, TDS and turbidity which were different. TDS of Dukan 1 project was slightly higher than Dukan 2 (148.9 vs. 145.9 respectively). Similarly turbidity of Dukan 1 was twice that of Dukan 2 (2.4 vs. 1.2). Overall, the parameter values were within standard ranges except Cl1- which was 19.8 (Iraqi standard 10 ppm) and dissolved oxygen which was 9 ppm (Iraqi standard 7-8 ppm). Microbiological results showed that 973 of the samples (91%) had an MPN of zero, 61 (5.7%) had an MPN of 2.2 and 35 (3.3%) had a higher MPN. The mean chlorination level for all samples was 1.12 (SD 0.44) .We can conclude that both Sarchinar and Dukan waters are acceptable for drinking purposes according to the parameters evaluated. We recommend to include monitoring heavy metals like Hg, Pb, Ni, Cr, Cd, Ag in the future; to consolidate the existing reporting system and to included samples from household tap water for analysis.

The low level of water in rivers in Iraq leads to poor water quality, on that basis; we need to assess Iraq's water resources for uses of irrigation and drinking water. This study present a model accounts for ground water quality by using a water quality index (WQI) for the region defined between the city of Kut and the city of Badra in Wasit province. this study relies on a system of wells set up along the path through the Badra –Kut  and around it  up to 78 wells. The study showed poor quality of ground water in the region of study and it is unsuitability for irrigation and drinking water, as well as provided a solution to the water accumulated in the Shuwayja to reduce the bad effect on groundwater by using a system of branch and collection canals  then pumping at the effluent  of Al  Shuwayja in seasons of rainy season ..Water quality index calculated depend on the basis of various physic-chemical parameters as PH, Ec , TDS, TSS, Nacl , SO4 ,Na , and  Mg. The resultant and analytical are present with use of Arch GIS program – geostastical analysis for the water index and water quality parameters

The relevance of the chosen topic is closely related to the development of a system for monitoring the implementation of the May Presidential Decree (2018) to increase life expectancy and improve the quality of life of the population. It has been stated that despite the positive dynamics of life expectancy over the past decade, Russia still has a huge regional differentiation (16,6 years for women, 18,2 years for men in 2016) and an average gender gap - 10,6 years. The choice of factors affecting the gender gap in life expectancy in Russian regions is supported by a conclusion most common in foreign studies that climatic conditions, living conditions, the quality of food and drinking water, alcohol consumption are essential components of public health and life expectancy.The article provides an overview of studies on assessment factors of life expectancy, presents the authors’ approach to identifying gender gaps in life expectancy, living conditions, and lifestyle affecting the indicator of life expectancy. The paper presents the results of a comparative analysis of gender gap in life expectancy in Russia and foreign countries. The paper studies the correlation between living conditions and lifestyle, and life expectancy.Classification of the regions by the life expectancy at birth for men and women is an important component of this study. The authors used Rosstat data for 2016 and the k-means method to select three clusters of Russian regions taking into account gender, living conditions and lifestyle. The paper identifies similar health problems of the regions that are associated with alcohol consumption, poor nutrition and poor quality of drinking water, poor housing and living conditions. The lowest life expectancy rates for men and women are recorded in regions of the 1st cluster (Jewish Autonomous Region, Republic of Tuva, Chukotka Autonomous Area). High mortality rates are a result of external causes. There is a poor quality of drinking water and poor nutrition, excessive alcohol consumption, and inadequate housing conditions.Based on the obtained results were determined possible reserves for reducing the gender and regional differentiation of life expectancy.
