O mineralizovanoj vodi u Gornjem Striževcu kod Babušnice

Abstract

With hydrochemical testings of underground waters which were performed during the years 2015 and 2016 in the wider space of structural basin Babušnica, the appearance of mineral water was recognized in one of the dug wells in a village Gornji Striževac. As for hydrogeological views, it's about a chamber of mineral water which was formed as a part of "the first aquifer zone" in the sewer built from sandclay and gravel sediments of Pliocene (Pl). The water is mildly mineral (M=1012mg/l) and, by the Alekin classification, belongs to the class of hydrocarbons, calcium group of type 1 (Cl1,01Ca29.8). With the use of a "Genetic Diagram" (D'Amore, Scandiffio & Panichi, 1983), ion hydrocarbonates (HCO3 - ) are dominating in the water. There is the impoverishment of sulfates (SO42-), and the content of chlorid ions (Cl) is smaller than sodium ions (Na+). In a cationic composition, calcium ions (Ca2+) are, by their value, above the cumulative content of sodium ions (Na+) and potassium (K+). An instability of ratio in content was spotted, between sodium ions (Na+) and magnesium (Mg2+). It is also characteristic that a ratio change appears from time to time Ca2+ + Mg2+ ↔ HCO3even though the hydrocarbonated ion is dominant in mineral water. Taken in entirety, conditions for the forming of mineral water in Gornji Striževac are connected to the interaction of ground water with hydrocarbonated-calcium content (HCO3-Ca2+) with the geological environment (volcano-detitric rocks otb, Pliocene sediments Pl). According to the volume of analyzed parameters, mineral water is characterized by the raised values of: boron (B), iron (Fe), manganese (Mn). Water is not correct for drinking because of high values of nitrates (NO2), amonium ions (NH4 ) and oxidability (KMnO4). Water has also low radioactivity.
