Temporal variability of water chemistry in the Cherkashinskaya well No. 36-RG (Tobolsk district, Tyumen region)

Abstract

This article focuses on a temporary change in the chemical composition of water in the Cherkashinskaya well No. 36-RG, which is located in the Tobolsk district near the village of Shestakovo. The impact of underground mineral waters on catchments and watercourses can be caused by the open gushing of orphaned geological exploration wells. This can lead to the disturbance of the hydrochemical regime of neighbouring water systems. Publications on this topic are available not only in Tyumen region, but also throughout the Russian Federation. For example, scientific articles and conference proceedings, such as "Groundwater of the East of Russia" (2018), "Issues of studying surface and groundwater of Siberia" (2021), and the International Conference "Underground Waters 2023", are available. The study highlights the behavior of various components of water composition. The article presents changes in the mineralization of groundwater and identifies the main sources of negative impact on its quality. In 2019, the chemical composition of the water in the containing well underwent a transformation. This article focuses on the changes in the chemical composition of water from the Cherkashinskaya well No. 36-RG and its impact on the surrounding areas.
