Abstract

The article presents a comprehensive analysis of the river basin condition and water quality of the Inya River in the Kemerovo region over recent decades, specifically covering the periods from 1998 to 2003 and from 2017 to 2022. The study includes a comparative assessment of water quality changes, examining pollutant concentrations and the influence of various anthropogenic factors on the chemical composition of river water. Special attention is paid to identifying pollution sources, such as industrial discharges, agricultural and domestic wastewater, and atmospheric emissions that subsequently deposit onto the river basin surface. The article analyzes changes in the chemical composition of water and establishes correlations between water quality indicators and various characteristics, such as the disturbed land area. The findings show a notable improvement in water quality in recent years, attributed to integrated water purification measures and reduced anthropogenic load. However, unresolved issues remain, necessitating further improvement of treatment systems, enhanced monitoring of compliance with environmental standards, and the adoption of modern digital technologies for pollution monitoring.
