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 the article the variability of concentration of selected chemical proper-ties as well as chemical composition of underground waters intaken by drilled wells on the area of carpathian part of Malopolska province was presented. Men-tioned underground waters occured in the clastic and flysch rocks of Quateriary, Paleogene and Cretaceous period. The chemical properties included the amount of total mineral solids, total hardness and pH reaction of water, whereas chemi-cal composition - the analysis of HCO3-, SO42-, Cl-, NO2-, NO3-, PO43-, Ca2+, Mg2+, Na+, K+, Fe2+, Mn2+ iones concentration. As regards total mineralization the studied waters were described as normal sweet, slightly alkaline and medium hard. Most often they contained higher levels of Fe2+ and Mn2+ iones, sometimes also SO42-, Cl- and Na+. The quantity of statistics variability coefficient of analyzed chemical parameters showed that pH reaction of studied waters was classi-fied as low variable, total mineral solids, total hardness, HCO32-, Ca2+ and Mg2+ (except Quaternary waters), K+ (except Quaternary and Cretaceous waters) as medium variable, Cl-, NO2-, NO3-, PO43- i Mn2+ (only in Quaternary waters), Na+ and K+ (only in Cretaceous waters), Fe2+ and Mn2+ as higly variable (variability coefficient > 100). As regards hydrochemical properties analyzed Quaternary waters were ...
