Sudety Mts. - Opis:
- The study area-the Bystrzyca River catchment extends over about 1500 kmexp.2 of the Sudety Mts foreland [SW Poland]. The chemical composition of groundwater collected in 2004 from 57 sampling wells within the Holocene-Pliocene and Miocene aquifers throughout the Bystrzyca River catchment was analyzed. The results served to study the hydrogoechemical background and quality of groundwater. Groundwater of both aquifers were usually dominated by HCO3- (with the background of 47–400 mg/l and 110-260 mg/l for Holocene-Pliocene and Miocene aquifers, respectively, SO4exp. 2- [9–200 mg/l; 6-82 mg/l], Caexp.2+[20-101 mg/l; 32-72 mg/l] and Mgexp.2+[4.8-20 mg/l; 7.2-16 mg/l] ions, but the quality of groundwater from theMiocene aquifer was relatively better. The similar chemical composition of the both aquifer’s groundwater shows that the Miocene aquifer was reinforced by water seepage from the upper Holocene-Pliocene aquifer. Thus, the water from the Holocene-Pliocene aquifer could have been the source of anthropogenic pollutions to the Miocene aquifer. However, groundwater from the Miocene aquifer contain more Fetot and Mnexp.2+ ions, attributed to geogenic influences. Concentration of toxic ions like NOexp.2- and probably anthropogenic NOexp.3- and Clexp.- ions in the studied groundwaters was low, not exceeding the limits for potable water [as defined by Polish standards; Official Journal. No. 203, item1718].
