“…These assessments consider parameters such as pH levels, dissolved oxygen, turbidity, nutrient concentrations, and the presence of pollutants. By monitoring and evaluating surface water quality, stakeholders can identify areas of concern, implement appropriate management strategies, and work towards maintaining and improving the overall health of the region's water bodies [36]. It is crucial to continue monitoring and implementing effective water management practices to preserve the quality and sustainability of the surface water resources in the Karaganda region for future generations [37].…”

The research aims to analyze the complex water balance, surface water quality, and water resources management in the Karaganda region. A thorough investigation involved examining 119 lakes and 12 rivers within the region. The study revealed that the annual river flow into the Karaganda lakes and their subsequent outflow from the territory was notably meager, accounting for only 0.935% and 3.031%, respectively, primarily due to the scarcity of water bodies in the region. As for water quality, none of the lakes qualify as "highly suitable water" (>50), necessitating further treatment to make them drinkable. Only a small fraction, 4.6% of the lakes, display water quality scores ranging from 50 to 100, indicating the urgent need for substantial remediation efforts. Additionally, a considerable proportion, 47.7% of the lakes, fell within the water quality range of 100-200, demanding treatment before appropriate use. Furthermore, a noteworthy 11% of the lakes were deemed "unsuitable for drinking" (>300), while 36.7% are classified as "very poor water" in the range of 200-300.

Accumulation of Heavy Metals in Bottom Sediment and Their Migration in the Water Ecosystem of Kapshagay Reservoir in Kazakhstan

et al. 2022

The bottom sediment of reservoirs has many functions. Among them, matter sorption is a very important one, and results in many side-effects on the reservoir sediment forming the water–bottom sediment system. As a result, bottom sediment can also be an indicator of anthropogenic water pollution. There is only very little knowledge of this situation in the study area. The main objective was the analysis of heavy metal accumulation in bottom sediment, as well as their ability to migrate throughout the water–bottom sediment system and their spatial distribution in the Kapshagay Reservoir in Kazakhstan. Heavy metal concentrations, in the both water samples and the bottom sediment, were determined using the atomic absorption spectrophotometric method. Surfer software was used to visualize the processes of migration and accumulation. Another objective was the development of model maps of the spatial distribution of metals in the reservoir water area, which indicated significant anthropogenic loads. It is obvious that both the transboundary inflow of the Ili River and the inflow from small rivers in the territory of Kazakhstan are the reasons for the anthropogenic water and sediment load. The results of the spectrometric analysis verify the water pollution in the reservoir, revealing increased concentrations of zinc reaching up to 10.8 µg/L and lead up to 32.7 µg/L, transported by the transboundary runoff of the Ili River and by the small rivers on the left bank into the Kapshagay Reservoir. Sediment concentrations close to the central part and dam zone of the reservoir reached the following values: zinc up to 37.0 mg/kg and lead up to 8.8 mg/kg. The results of this study indicate a significant anthropogenic load of the ecological conditions of the Kapshagay Reservoir. This is discussed and compared with other relevant studies.

“…A wide review of the literature on the selection of optimal indicators for a comprehensive assessment of surface water quality and compelling facts about the need for systematic monitoring of the dynamics of the spread of pollutants for an objective assessment of water quality and in particular transboundary water basins and the establishment of criteria for assessing the quality of surface waters taking into account natural features are presented in [8,9].…”

The results of chemical analyses of the Vakhsh river and its tributaries and the calculations of the main criteria for the water applicability for irrigation purposes are presented: the proportion of sodium cations capable of absorption, dissolution, ion exchange, and the proportion of magnesium. It was found that the waters of the Vakhsh river and its tributaries (Kyzylsu, Muksu, Obikhingou and Surkhob) are favorable for irrigation of agricultural land. On the values of the magnesium cations ratio to calcium cations the Vakhsh river and tributaries water correspond to the first class of «soft waters». It is shown that due to the surface and underground water exchange, underground water reservoirs are enriched by cations of alkaline and alkaline earth elements. The underground water reservoirs of the Vakhsh tributaries basin on the water quality terms are also suitable for irrigation purposes.
