“…Also, deeper groundwater aquifers may be affected due to drawdown of the groundwater table. Previous studies in the region have shown that the drawdown of the groundwater table may be up to 80 m with a cone of depression area of up to 150 km 2 [46]. This facilitates the transport of shallow pollutants to deeper groundwater levels.…”

Infant mortality in Kazakhstan is six times higher compared with the EU. There are several reasons for this, but a partial reason might be that less than 30% of Kazakhstan’s population has access to safe water and sanitation and more than 57% uses polluted groundwater from wells that do not comply with international standards. For example, nitrate pollution in surface and groundwater continues to increase due to intensified agriculture and the discharge of untreated wastewater, causing concerns regarding environmental and human health. For this reason, drinking water samples were collected from the water supply distribution network in eight districts of Almaty, Kazakhstan, and water quality constituents, including nitrate, were analyzed. In several districts, the nitrate concentration was above the WHO and Kazakhstan’s maximum permissible limits for drinking water. The spatial distribution of high nitrate concentration in drinking water was shown to be strongly correlated with areas that are supplied with groundwater, whereas areas with lower nitrate levels are supplied with surface water sources. Based on source identification, it was shown that groundwater is likely polluted by mainly domestic wastewater. The health risk for infants, children, teenagers, and adults was assessed based on chronic daily intake, and the hazard quotient (HQ) of nitrate intake from drinking water was determined. The non-carcinogenic risks increased in the following manner: adult < teenager < child < infant. For infants and children, the HQ was greater than the acceptable level and higher than that of other age groups, thus pointing to infants and children as the most vulnerable age group due to drinking water intake in the study area. Different water management options are suggested to improve the health situation of the population now drinking nitrate-polluted groundwater.

“…Currently, in Kazakhstan, Russia and several other post-Soviet countries, mainly underground mineral waters are used for balneological treatment, which in recent years have been drilled in many new areas, sometimes from very deep depths. Springs and mineral groundwater were actively studied in Soviet times, for example, hydrochemical characteristics and typification of mineral springs opened by wells in Aralsk, Chelkar, Donguztau and several other areas of Western Kazakhstan were given (Sydykov, 1999;Mukhamedzhanov et al, 2020;Osipov et al, 2020). Springs belong to the most common and numerous water bodies, collectively forming an important part of the hydrographic network of the region.…”

The use of springs is becoming increasingly important in tourism. There are many springs in Western Kazakhstan that can be used to develop various types of tourism. Springs can be used for health, ecological, religious and other types of tourism. Today, health and spa tourism is one of the fastest growing sectors of world tourism. The historical and cultural heritage, and biodiversity associated with the springs also fascinate people, and many of them can become unique tourist destinations with high visual impact. The article gives characteristics of springs, self-flowing artesian wells, underground cave lakes of Western Kazakhstan and indicates their tourist potential for travellers and local. However, despite the high recreational potential of springs, tourism as a whole is not developed enough to provide quality tourism services and attract a large number of tourists to the region. An analysis of the tradition of tourist use of springs has been carried out and the main types of modern recreation are justified based on an assessment of the tourist potential of springs.
