Hydrogeochemical anomaly in waters of the pyrite deposit area in Wiesciszowice (Western Sudetes Mts., SW Poland)

摘要

In the dormant pyrite mine in Wiesciszowice (Western Sudetes Mts.) a distinct hydro-geochemical anomaly was discovered, expressed by extremely high concentrations of iron, sulphates and aluminium in surface- and groundwaters. The waters contain also high amounts of such heavy metals, like Cu, Pb, Co, Cr and Zn. Sulphate and iron rich waters that drain the old mine area have great influence on the quality of the surface waters. A strongly acidic reaction pH, frequently below 3, speeds up a process of heavy metals transfer to the solution.
