Silesian Beskydy Mts.; selected spring-drainage; water-quality parameters

Selected chemical composition parameters were monitored in five groundwater springs in Silesian Beskydy Mountains (cadastral units of Nýdek, Bystřice n.O., Písečná, Istebna), from two main hydrogeological aquifers of the Silesian nappe units. Sampling and analysis in CR Silesian Beskydy Mts. profiles three only vegetation periods of the yeras 2002, 2003, 2004 with one control sample 2007. All springs are discharging groundwater of the shallow descent cycle from precipitation and snow melting with variable discharge rates in order of tenths l.s-1. This research was realized of wiew the natural specifity of this area and indicators of possible anthropogenic impacts. The total mineralization of groundwater generally corresponds with Ca, Mg, HCO3, SO4 ions quantity, and shows significant deficit Ca+Mg according to water management criteria. The possible impacts of the historically strong air pollution and environmental acidification to groundwater were not verified.
