Impact of Zn-Pb mining in the Olkusz ore district on the Permian aquifer (SW Poland).

Motyka J, Postawa A - Environ Sci Pollut Res Int (2013)

Bottom Line: Long-term extensive mining of Zn-Pb ores in the Olkusz area resulted in significant changes of water table levels and chemical composition of water in all aquifers in this area.Short-term effect was freshening in the zones of contact with overlying the Triassic limestones and dolomites.As a result of all these processes, hydrochemical type of water shifted from multi-ion types with various combinations of ions towards higher shares of sulphates, calcium and magnesium.

ABSTRACT
Long-term extensive mining of Zn-Pb ores in the Olkusz area resulted in significant changes of water table levels and chemical composition of water in all aquifers in this area. Within the Permian aquifer, hydrochemical type of water evolved in two general stages. Short-term effect was freshening in the zones of contact with overlying the Triassic limestones and dolomites. Long-term effect was a change in flow pattern and, as a consequence, an inflow of naturally altered and antropogenically contaminated water from the Triassic aquifer into the Permian complex. This was especially intensive in densely fissured and fault zones. As a result of all these processes, hydrochemical type of water shifted from multi-ion types with various combinations of ions towards higher shares of sulphates, calcium and magnesium.

Mentions: In long-term perspective, when flow conditions reach semi-steady state, migration of contaminated water from the Triassic aquifer began to affect the chemical composition of inflows observed in the Permian conglomerates (see Fig. 7).Fig. 7
