“…Only in recent decades, up to 52 km 3 / year of wastewater is discharged into water bodies of the Russian Federation annually, of which 19.2 km 3 are subject to treatment. Of this amount, only 11% (2 km 3 ) goes into water bodies cleaned up to established standards; 72% (13.8 km 3 ) -insufficiently cleaned or non-disinfected, and 17% (3.4 km 3 ) -without any cleaning and disinfection (Onishchenko, 2010;Rakhmanin et al, 2016;Zavarzin, 1990). At the same time, the implementation of federal and regional programs to improve drinking water quality, along with positive factors, may in some cases lead to a deterioration in the quality of drinking water due to multistage complex water treatment.…”

“…This leads to deterioration or levelling of sanitaryindicative microorganisms` indicator value, which help to carry out epidemic control of surface water bodies safety in consent with the current water-sanitary legislation. This can lead to epidemically dangerous situations in which there may be a discrepancy in water bodies quality assessment according to the existing standardised indicators for pathogenic enterobacteria detection in water (Rakhmanin et al, 2016). The following section discusses the ecology and the quality of drinking water in India and Russia.…”

Despite the efforts of the United Nations General Assembly to promote sustainability as a vehicle of resource management and tackle social inequalities through the 17 Sustainable Development Goals, the challenges remain. Therefore, the need to solve the fundamental problem of life “water-energy-food” (henceforth WEF) creates the basis for an integrated approach to eliminating the obstacles that arise on the path of sustainable life evolution on Earth. The WEF concept based on a socio-ecological systemic approach is a platform for the most rational approach to solving complex problems and adapting to climate change. At the same time it contributes to regional economic development. Taking examples from India and Russia, this commentary aims to highlight the challenges of water and sanitation of the world.

This paper analyzes the parasitological state of natural water bodies — rivers, lakes, springs, wells, as sources of drinking water supply, according to the content of round and flat helminthes. It is shown that climate aridization, which has been taking place in recent decades, causes, first of all, a decrease in the hygienic safety of surface water sources and an increase in the number of some helminth eggs in them, in particular, cestodes, which is associated with an increase in the average annual temperature under conditions of climate aridization. The water of surface water sources has an unfavorable parasitological composition in the presence of helminth eggs in the invasive and non-invasive stages of the life cycle. Reservoirs of the middle and southern latitudes are untidy from the point of view of the parasitological background in terms of the content of helminths. Contamination of water supply sources by eggs and larvae of parasitic worms in arid regions is confirmed by the morbidity of the local population. In the article, we noted various topical methods of preventing specific parasitic diseases — medical examinations of the population, parasitological studies of drinking water, parasitological control of raw materials and fish products, hygienic education and medical examination of the population for the purpose of early active detection of the infected. The presented up-to-date information on the results of sanitary and parasitological studies of environmental objects in different regions of Russia showed that the greatest contamination of round and flat helminths with eggs is characteristic of the southern regions. The example of the Saratov region shows the change of the fauna of endoparasites from humid to subarid and arid regions — nematodes are represented in the Right Bank of the region, and cestodes (Echinococcus) in the Left Bank. Cestodes are most characteristic of an arid climate.

Background: Surface reservoirs remain one of the priority sources of drinking water in the Russian Federation whereas the increasing anthropogenic effect on the environment does not exclude the possibility of contamination of surface waters with toxic compounds. The use of traditional methods of water disinfection with active chlorine aggravates the situation and leads to formation of highly toxic organochlorine compounds. In this regard, one of the urgent hygienic problems is to establish health effect of these toxicants in the population including its most sensitive groups. The objective of the study was to establish and quantify the relationship between concentrations of chloroform and its derivatives in drinking water and blood levels of organochlorine compounds in children consuming potable water with a higher content of chlorine and its derivatives. Materials and methods: The study was conducted on six territories of the Perm Region constituting an observation area where drinking water was noncompliant with hygienic standards by a number of indices, and a comparison area. The analysis of trihalomethanes in drinking water samples was carried out in accordance with the requirements of sanitary regulations SanPiN 2.1.4.1074–01. The levels of trihalomethanes (chloroform, carbon tetrachloride, dibromochloromethane, dichlorobromethane, and 1,2-dichloroethane) in children’s blood samples were analyzed by capillary gas chromatography in combination with a specific detector to increase selectivity and sensitivity of determination. We used a Kristall-5000 gas chromatograph with an Optima-5 capillary column (25 m × 0.32 mm × 0.5 μL) and a selective electron capture detector (ECD). Results: The data of comprehensive chemical analyses of average levels of trihalomethanes in blood samples of children consuming drinking water with an increased content of determined compounds (up to 3.5 MPC) and the water complying with hygienic standards are presented. We observed significant differences (р<0.005) between two groups in the blood levels of chloroform, carbon tetrachloride, and 1,2-dichloroethane that were 5.6, 6 and 24 times higher in children of the test group compared to the controls. Conclusion: We revealed a statistically significant causal relationship between the increase in chloroform concentrations in drinking water and the increase in blood levels of chloroform in children described by the equation у=0.00188+0.01782х (R2=0.263, p=0.0018).
