Influence of contaminated Vistula River water on the groundwater entering the Zakrzowek limestone quarry, Cracow region, Poland
Motyka J. , Postawa A. ,
Abstract:
Chemical composition of water inflows in the Zakrzowek quarry, developed in fractured and karstified Upper Jurassic limestones, is controlled by infiltration of polluted water from the Vistula River and by infiltrating meteoric water. The river water TDS value is 2.5 g/dm(3). The quarry waters have 0.6-2.0 g/dm(3) TDS. Highly mineralised waters belong to Cl-Na type. With decreasing TDS the percentage of sulphates, calcium, magnesium and hydrocarbonates increases. This seems to result from various processes including dilution of polluted river water, leaching of aquifer rocks, and ion exchange. The transfer time of river water to the quarry is about 100-120 days. Concentration of contaminants contained in the river water declines during the migration through limestones to the quarry
