Abstract

The Main Key Heritage Adit in Zabrze was used during from 1799 to 1953 to drain a series of underground coal mines and is the longest such facility in Europe. It discharges water of variable quality to the Bytomka River. At times, the adit water has greatly exceeded allowable discharge water quality limits. The refurbishment of the adit at the beginning of the twenty-first century allowed tourists to access 2.5 km of the original 14.25 km of tunnels. It also enabled the monitoring of groundwater in this part of Zabrze. Three series of water samples from leaks at the adit and the “Carnall” shaft (34 samples in total) were collected from 2017 to 2018. The total dissolved solids content of the samples ranged from 640 to 2670 mg/L with pH ranging from 6.7 to 8.5. Waters belong to various chemical types, from Ca-HCO3-SO4 and Ca-HCO3-Cl to Ca-Na-Mg-Cl-HCO3-SO4. High concentrations of metals (e.g. Fe up to 64.4 mg/L) and anthropogenic pollutants such as NO3 (up to 151.4 mg/L) were observed. The pollution is caused both by natural processes (weathering of sulfides) and anthropogenic factors (long-term mining activities, intensive land use, and past and present leaks of city sewerage). The hydrogeological role of the adit and the possibilities of its multifunctional use may serve as an example of good practices that can be used during the rehabilitation of closed mines elsewhere in the world.
