“…The river basin is also polluted by other toxic substances: mercury, organochlorine compounds, waste from mining industries and heavy and non-ferrous metals [50]. A limited number of publications devoted to the study of the hydrochemical composition of surface waters in Northern Kazakhstan have been identified in scientific literature [38,[44][45][46]. These existing few scientific studies of surface waters are focused mainly on the Ishim River, the most detailed description of the formation conditions of which was carried out in the 20th century [47,48].…”

For the first time in scientific literature, this work addresses the current situation of the Ishim River water quality in the Akmola Region (Northern Kazakhstan). This work uses environmental monitoring techniques to analyze the current state of surface waters in the river. The content of main ions, biogenic and inorganic ions, heavy metals, organic impurities in seasonal and annual dynamics have been studied. Results show that, despite the tightening of requirements for wastewater discharge into the Ishim River basin, a number of water quality indicators did not fulfill the regulatory requirements for surface water bodies during 2013–2019. It has been identified that the greatest pollution in the Ishim River is brought by enterprises of the Karaganda-Temirtau technogenic region, located in the upper reaches of the river. Future water quality monitoring is needed and should include increasing the number of sampling locations and the sampling frequency in order to characterize the spatial and temporal variability of hydrochemical parameters and allow a comprehensive monitoring of legally fixed water quality parameters/indicators.

“…In Russia, approximately half of the total streamflow volume accounts for small rivers [Kuznetsov & Petrov 2017, Nevskaya et al 2019]. Due to minor runoff volumes in small rivers, the self-remediation process is slower, and the longterm anthropogenic impact leads to the degradation of water ecosystems [Kremcheyev et al 2020, Puzanov et al 2015]. The impact of mining industries results in increased silting and technogenic sedimentation [Chalov et al 2015a, Chukaeva et.…”

The drainage flows of metal loads into the drainage and infiltration waters of mine dumps of enterprises have a dramatic effect on small rivers in industrial regions. The paper considers the outcomes of geochemical monitoring of the Karagaily River and assesses the transformation of the acid-base conditions depending on the influence of the facilities of the enterprise. The results of engineering and environmental surveys, including sampling of bottom sediments, laboratory preparation, chemical elemental analysis of samples and X-ray diffraction analysis of mineral composition, were presented. A complex technogenic alkaline sorption-hydroxide barrier was found at the mixing point of acidic river waters (the influence of dump and quarry waters) and alkaline wastewater of treatment facilities, where the deposited iron hydroxide adsorbs ore minerals, which reduces their outflow into larger rivers and increases the self-purification potential of the river. Further interaction of iron hydroxide with the acid mine drainage and calcium bicarbonate of wastewater results in pyritization of bottom sediments. Excavation and dewatering of the pyrite-containing bottom sediments will allow their joint use with tailings and ore-processing waste for re-extraction useful components.
