In the article was presented variability of iron and manganese ions concentration during the decade 1993-2002 in the underground waters of „Bzin" water intake that supply water pipe for Skarżysko-Kamienna city. The Bzin water intake includes six drilled wells of 37 to 60 meters depth and 74 to 341 m3/h capacity that intake underground waters from carbonated, slotted Triassic formation. Conducted research indicated very high variability of analyses compounds. The analysis of Fe and Mn ions variability in the underground Triassic waters of Bzin intake showed that in the well II and III waters decreasing of Mn and Fe concentrations, in the wells I and Ia decreasing only of Mn concentration and increasing of Fe level, however in wells IIIb and IV increasing both Mn and Fe concentrations was followed during progressive exploitation. In case of Fe ions, concentration in exploited water reached up to 1,52 mg/dm3 (well I) and manganese up to 0,78 mg/dm3 (well Ia). First class waters (very good quality) occurred throughout research period in the well 3b, and the worst third and forth class: in the year 1997, in the well 4, that was connected with high concentration of Fe and Mn ions, and throughout whole ...
In this study characteristics of drilled wells and artesian waters taken from them that occured in the formations of Quaternary, Miocene, Cretaceous, Jurassic, Triassic and Carboniferous period of the Extra Carpathian part of Małopolska province, was presented. The study area includes the central and northern part of Małopolska province, where such a morphological and tectonic units like Oświęcim and Sandomierz Valleys (the Carpathian Depression), Miechów (Nida) Trough, Śląsko-Krakowska Upland (Monocline) and Górnośląska Upland (Depression) were located. The artesian waters of study area taken from 116 drilled wells with depth from about 14,5 (Quaternary) to 1923,5 m (Miocene) and unitary yield from 0,001(Jurassic) to 375,0 (Triassic) m3·h-1·m-1 were characterised by artesian pressure from 2,0 up to 702,1 m H2O and useful pressure from 0,1 up to 18,5 m H2O. The unitary yield of Quaternary wells varied from 0,54 to 7,06 m3·h-1·m-1, Miocene wells 0.01–10.38 m3·h-1·m-1, Creatceous 0.03–52.94 m3·h-1·m-1, Jurassic 0.001-14.8 m3·h-1·m-1, Triassic 9.35-375.0 m3·h-1·m-1 and Carboniferous 2.99 m3·h-1·m-1. The highest unitary yield was detected in Triassic and the lowest in Quaternary formation. The artesian pressure ranged from 10.0 to 50.0 m H2O and useful pressure 1.0–5.0 m H2O characterised majority of wells in the study area, respectively 43 (36.8% of all) ...
In this study characteristics of drilled wells and artesian waters taken from them that occured in the formations of Quaternary period, Miocene period, paleoStefan Satora 168 gene, Oligocene, Cretaceous, Jurassic, Triassic and Carboniferous period of Małopolska province, was presented. The artesian waters taken from 116 drilled wells with depth from about 14,5 (Quaternary) to 5261,0 m (Oligocene) and unitary capacity from 0,001(Jurassic) to 375,0 (Triassic) m3·h-1·m-1 were characterised by artesian pressure from 2,0 up to 3021,0 m H2O and useful pressure from 0,1 up to 245,0 m H2O. The highest artesian and useful pressures were found in wells taken from clastic, flysh Oligocene layers of Interior Carpathian, and the lowest – in wells the was recharged by sandy-gravel of formation Quaternary. The highest amount of artesian wells on the studied area, 69 of artesian wells that constituted about 42,6% of all, is recharged by carbonate measures of Mesozoic era. ...
