This article highlights the problems associated with heavy metal contamination of the soil near the Kargalinka tailings dam and the village of Kyzylzhol. This points to the problem of reclamation and the importance of solving this pressing problem. Soil pollution near tailings dumps, where mining waste is stored, poses a serious problem for the environment and public health, especially if the tailings dumps are saturated with heavy metals. The increased concentration of heavy metals in the soils near the tailings dam was Pb 55,9; Cu 6,8; Zn 45,2; Cd 4,7; Ni 8,2; As 5,1; Hg 4,8; Cr 13,7 mg/kg. Soil contamination with heavy metals can have long-term effects on ecosystems, agriculture, and human health. In many cases, these heavy metals are difficult to reclaim, which makes their effects long-term. As a result, soil pollution near tailings dumps has become one of the most acute environmental problems in the southern region of Kazakhstan, related to the consequences of the mining industry.
