AB  - Aquifer contamination by petroleum hydrocarbons leads to measurable changes of groundwater hydrochemistry, primarily due to the microbiological activity. This study analyzes this phenomenon at an historical kerosene-contaminated site in Vitanovac (central Serbia). Due to the long-term hydrocarbon contamination and exposure to aerobic and anaerobic biodegradation mechanisms, the lowest concentrations of O-2, NO3-, and SO42- (electron acceptors) and the highest concentrations of Mn and Fe (products of microbial metabolic activity) overlap. The terminal redox-accepting processes in groundwater ranged from oxygen reduction to sulfate reduction. The most anoxic processes were registered in piezometers closest to the source of contamination, as was also confirmed by the redox potential (Eh) measurements. High electrical conductivity values and the highest TOC, SiO2, and Al concentrations also overlap in the contaminated zone close to the source of contamination. Scanning electron microscopy study of quartz grains from the zone undergoing the impact of biodegradation confirmed the occurrence of weathering microscale processes on mineral surfaces. Taking all these factors together, it seems reasonable to assume that microbiological activity has caused the enhanced weathering of silicate minerals.

AB  - This paper provides insight into the quality of groundwater used for public water supply on the territory of Temerin municipality (Vojvodina, Serbia). The following parameters were measured: color, turbidity, pH, KMnO4 consumption, total dissolved solids (TDS), EC, NH4+, Cl-, NO2-, NO3-, Fe, Mn, As, Ca2+, Mg2+, SO42-, HCO3-, K+, andNa(+). The correlations and ratios among parameters that define the chemical composition were determined aiming to identify main processes that control the formation of the chemical composition of the analyzed waters. Groundwater from three analyzed sources is Na-HCO3 type. Elevated organic matter content, ammonium ion content, and arsene content are characteristic for these waters. The importance of organic matter decay is assumed by positive correlation between organic matter content and TDS, and HCO3 content. There is no evidence that groundwater chemistry is determined by the depth of captured aquifer interval. The main natural processes that control the chemistry of all analyzed water are cation exchange and feldspar weathering. The dominant cause of As concentration in groundwater is the use of mineral fertilizers and of KMnO4 in urban area. The concentration of As and KMnO4 in the observed sources is inversely proportional to the distance from agricultural land and urban area. 2D model of distribution of As and KMnO4 is done, and it is applicable in detecting sources of pollution. By using this model, we can quantify the impact of certain pollutants on unfavorable content of some parameters in groundwater.

AB  - This paper provides insight into the quality of groundwater used for public water supply on the territory of Kikinda municipality (Vojvodina, Serbia) and main processes which control it. The following parameters were measured: color, turbidity, pH, KMnO4 consumption, TDS, EC, NH4 (+), Cl-, NO2 (-), NO3 (-), Fe, Mn, total hardness, Ca2+, Mg2+, SO4 (2+), HCO3 (-), K+, Na+, As. The correlations and ratios among parameters that define the chemical composition were determined aiming to identify main processes that control the formation of the chemical composition of the analyzed waters. Groundwater from 11 analyzed sources is Na-HCO3 type. Intense color and elevated organic matter content of these waters originate from humic substances. The importance of organic matter decay is assumed by positive correlation between organic matter content and TDS, HCO3 content. There is no evidence that groundwater chemistry is determined by the depth of captured aquifer interval. The main processes that control the chemistry of all analyzed water are cation exchange and feldspar weathering.

AB  - The geothermal waters of the Province of Vojvodina in northern Serbia, south part of the Pannonian Basin, are characterized by temperatures between 24 and 75 degrees C. Dominant ions in these waters are sodium and bicarbonate, but the waters also contain significant amounts of calcium, magnesium, potassium, chlorides, and ammonium. Components that are of balneological significance include iodine, bromine, fluorine, strontium, lithium and barium, metasilicic and metaboric acids. Reported are the physicochemical parameters of this groundwater drilled from 200 to 1200 m depth in Vojvodina's territory. Hydrogeochemical studies were carried out in this area with the objective of identifying the geochemical processes and their relation such groundwater quality. Weathering of silicate minerals controls the concentration of major ions such as sodium, calcium, magnesium and potassium in the groundwater of this area. The reverse ion exchange process controls the concentration of calcium, magnesium and sodium in hard rock formations, and dissolution of carbonate minerals and accessory minerals is the source of Ca and Mg, in addition to cation exchange in the sedimentary formations. In general, the chemical composition of the groundwater in, this area is influenced by rock-water interaction, dissolution and deposition of carbonate and silicate minerals and ion exchange. An attempt has been made to study quality of groundwater using multivariate statistical technique such as cluster analyses. Hydrogeochemical data for 13 groundwater samples were subjected to correlation and R- and Q-mode cluster analysis, where R-mode analysis reveals the inter-relations among the variables studied, and Q-mode analysis reveals the inter-relations among the samples studied.
