Coal Mine Drainage as a Source of Drinking and Industrial Water—The Upper Silesian Coal Basin, Poland

Abstract

Water is one of the most important resources found on Earth, essential for all forms of life. Both the quantity and quality of water resources are crucial for the health of the population and for economic sectors, making water a factor in determining a society’s standard of living. Mine water serves as an appealing source of both drinking and technological water. Regardless of the exploitation method, it must be pumped to the surface and, usually, treated to meet environmental standards. In most cases, it is discharged to rivers. In this article, we present a model of the use of mine water from three pumping stations of decommissioned coal mines in the Upper Silesian Coal Basin—Jan Kanty, Saturn, and Boże Dary. Water from these pumping stations is characterized by good qualitative and quantitative parameters. The results of the physico-chemical composition analyses carried out in the years 2012–2022 did not reveal any excessive amounts of toxic components or treatment difficulties. Given the long operational lifespan of these pumping stations and their existing water extraction infrastructure, they emerge as promising sources of both potable and industrial water supply, demanding minimal treatment efforts.
