AB  - The characterization and cleanup of groundwater contamination in hazardous-waste sites are of significant engineering and scientific importance. This study analyzes biodegradation fingerprints in groundwater, 25 years after the accidental leakage of kerosene (jet fuel) at the site in central Serbia. The long-term existence of hydrocarbon contamination and the presence of indigenous microbiological populations capable of biodegradation have been confirmed by the results of GCxGC-MS chromatography and microbiological characterization. Total petroleum hydrocarbons (TPH), geochemical indicators, and other parameters were spatially analyzed to provide insight into biodegradation occurrence. The lowest concentrations of electron acceptors (O-2, NO3-, and SO42-) and the highest concentrations of microbial metabolic products (Mn and Fe) overlap in the piezometers closest to the source of contamination, due to the occurrence of different biodegradation mechanisms. Based on the analysis of redox-sensitive compounds, the mixed oxic-anoxic processes in groundwater also correspond to the aforementioned zone, as confirmed by the redox potential (Eh) measurements. The results of cross-study analysis reveal further reduction of hydrocarbon contamination, the occurrence of less anoxic redox processes, and the increase of oxic conditions in groundwater. Overall, the results provide clear evidence of the biodegradation effects in groundwater and insight into their evolution under natural attenuation processes.

AB  - Spatial characterization of the contamination is a fundamental component of any remediation approach. Compared to conventional investigation methods, the laser-induced fluorescence (LIF) is a faster screening tool and provides the detection of hydrocarbon contamination in real-time. This investigation was conducted at a hydrocarbon-contaminated site in Pennsylvania, US. The presence of light nonaqueous-phase liquids (LNAPL) was detected in 6 of 17 LIF borings, with the reference emitter responses ranging between 45% and 225%. The depth of the response was highly accurate and valuable and provided insight into the spatial distribution of contamination. The results indicated that no substantial amount of LNAPL existed along the LIF borings profile, thus excluding this area as a preferential LNAPL migration pathway. The obtained results contributed to the characterization and remediation of this industrial site.

AB  - Due to their extensive use, petroleum hydrocarbons are among the most common groundwater contaminants Compared to the traditional methods of physical pumping of contamination from the aquifer and subsequent treatment (i.e., pump and treat), bioremediation is an economically cost-effective technology. The aim of this remediation approach is to transform biologically contaminants, most often by microbiological activity, into non-toxic compounds. More precisely, it is an active remediation process that involves biostimulation (increase of aquifer oxygenation, addition of nutrients) and/or bioaugmentation (injection of a concentrated and specialized population of microorganisms). Using both biostimulation and bioaugmentation, enhanced in situ groundwater bioremediation was applied at a hydrocarbon-contaminated site in Belgrade. The bioremediation treatment, applied over twelve months, was highly efficient in reducing the concentrations of total petroleum hydrocarbon (TPH) to acceptable levels. The concentration of TPH in the piezometer P-5 was reduced by 98.55 %, in the piezometer P-6 by 98.30 % and in the piezometer P-7 by 98.09 %. These results provided strong evidence on the potential of this remediation approach to overcome site-limiting factors and enhance microbiological activity in order to reduce groundwater contamination.

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  - A part of the Balkan ultramafic massif is situated in western Serbia and belongs to a mountain range with several prominent peaks, including Mt. Tara, Mt. Zlatibor, and Mt. Zlatar. The porosity of ultramafic rocks is generally very low, such that they are classified as nearly or completely waterless rocks. However, due to tectonic activity and exogenic processes over geologic time, some ultramafic rocks exhibit a certain level of secondary fracture porosity. Hydraulically interconnected fractures can form aquifers of the fractured type, such as the one found in Gruda on Mt. Zlatibor. On this location, the quality parameters of the groundwater in the fractured aquifer, drained via a spring called Bijela eesma, prompted detailed multidisciplinary investigations aimed at defining the elements of the aquifer for commercial water bottling purposes. Given that the investigations were comprehensive, the results allowed high-quality interpretation of the hydrogeologic conditions and provided the background for developing a hydrodynamic model of the fractured hydrogeologic system in the ultramafic rocks at Gruda. Modfiow software was used for modeling. This software is primarily intended for intergranular aquifers, but no programs are available for fractured aquifers in hard rocks with pronounced discontinuities. Modeling of the fractured aquifer in the ultramafic rocks at Gruda provided the following information: size of active infiltration surface, hydraulic conductivity of the porous medium, rate of recharge, residence time of a drop of groundwater from entry to exit, graphical representation of streamlines, and the like. Despite these difficulties, the results are satisfactory. The values of the analyzed parameters are believed to be objective and indicate a certain possibility of using Modflow in hydrodynamic modeling and solving hydrogeologic problems that involve hard rocks and fractured porosity. In practice, this is especially important for sanitary protection zoning of groundwater sources that rely on fractured aquifers.

AB  - Bujične pregrade se grade radi kontrole erozionih procesa i bujičnih poplava. U Srbiji, zakonski obavezujućim dokumentima, VOS (2002) i PPRS (2010), predviđen je koncept rešavanja vodosnabdevanja stanovništva i industrije regionalnim sistemima za koje se vode obezbeđuju izgradnjom visokih brana i formiranjem vodoakumulacija. Ovim konceptom često nije moguće zadovoljiti potrebe lokalnih zajednica u brdsko-planinskim područjima. U cilju doprinosa rešavanju problema vodosnabdevanja ovih uglavnom siromašnih sela, sprovedena su istraživanja mogućnosti da se podzemne vode iz zaplava bujičnih pregrada upotrebe za ovu namenu. Izvršena su terenska istraživanja i kabinetske analize projektne dokumentacije za brojne pregrade i zaplave na prostoru Srbije. Analizirane su potencijalne količine i kvalitet podzemnih voda u zaplavu kao resurs za vodosnabdevanje stanovništva. Rezultati istraživanja ukazuju na veoma povoljne mogućnosti zaplava za akumuliranje podzemnih voda u vidu izdani zbijenog tipa sa slobodni nivoom, u količinama koje se mogu upotrebiti za vodosnabdevanje. Konstatovano je: 1) da u povoljnim uslovima kod pregrada na vodotokovima sa stalnim doticajem i zaplavom velikih dimenzija postoji mogućnost akumuliranja dovoljnih količina podzemnih voda kao resursa za vodosnabdevanje, 2) poboljšanje kvaliteta infiltriranih voda procesom filtracije kroz intergranularnu sredinu zaplava do nivoa upotrebljivosti za vodosnabdevanje i 3) povoljni ekonomski parametri za otvaranje izvorišta u zaplavu u poređenju sa drugim vidovima izvorišta voda.

In Serbia, legally binding documents, VOS (2002) and PPRS (2010), provide the concept for the water supply of the population and industry by regional systems for which water is provided by building high dams and formation of reservoirs. With this concept, it is often not possible to meet the needs of local communities in mountainous areas. In order to contribute to solving the water supply problems of these mostly poor villages, research was conducted on the possibility of using check dam aggradation groundwater for this purpose. Field investigations and analysis of project documentation for numerous check dams and aggradations in Serbia were carried out. Potential quantities and quality of groundwater in the aggradations were analyzed as a resource for the water supply of the population. The results of the research indicate very favorable possibilities of the aggradations for the accumulation of groundwater in the form of unconfined or phreatic aquifer with a free water table, in quantities that can be used for water supply. It was stated that: 1) under favorable conditions, with check dams on watercourses with constant flow and large-scale aggradations, there is a possibility of accumulating sufficient quantities of groundwater as a resource for water supply, 2) improving the quality of infiltrated waters by the process of filtration through intergranular porous media of the aggradation, and reaching the level of water supply quality, and 3) favorable economic parameters for opening the source at the aggradation, compared to other types of water sources. The possibility that check dams, in addition to their traditional role, could be used for local water supply facilities was also highlighted.

abstract = "Bujične pregrade se grade radi kontrole erozionih procesa i bujičnih poplava. U Srbiji, zakonski obavezujućim dokumentima, VOS (2002) i PPRS (2010), predviđen je koncept rešavanja vodosnabdevanja stanovništva i industrije regionalnim sistemima za koje se vode obezbeđuju izgradnjom visokih brana i formiranjem vodoakumulacija. Ovim konceptom često nije moguće zadovoljiti potrebe lokalnih zajednica u brdsko-planinskim područjima. U cilju doprinosa rešavanju problema vodosnabdevanja ovih uglavnom siromašnih sela, sprovedena su istraživanja mogućnosti da se podzemne vode iz zaplava bujičnih pregrada upotrebe za ovu namenu. Izvršena su terenska istraživanja i kabinetske analize projektne dokumentacije za brojne pregrade i zaplave na prostoru Srbije. Analizirane su potencijalne količine i kvalitet podzemnih voda u zaplavu kao resurs za vodosnabdevanje stanovništva. Rezultati istraživanja ukazuju na veoma povoljne mogućnosti zaplava za akumuliranje podzemnih voda u vidu izdani zbijenog tipa sa slobodni nivoom, u količinama koje se mogu upotrebiti za vodosnabdevanje. Konstatovano je: 1) da u povoljnim uslovima kod pregrada na vodotokovima sa stalnim doticajem i zaplavom velikih dimenzija postoji mogućnost akumuliranja dovoljnih količina podzemnih voda kao resursa za vodosnabdevanje, 2) poboljšanje kvaliteta infiltriranih voda procesom filtracije kroz intergranularnu sredinu zaplava do nivoa upotrebljivosti za vodosnabdevanje i 3) povoljni ekonomski parametri za otvaranje izvorišta u zaplavu u poređenju sa drugim vidovima izvorišta voda.

AB  - Hyperalkaline (pH gt 10.5) springs are extremely rare. There are only about ten in the entire world. This type of water has been identified in an ultramafic massif in central Serbia, on Mt. Studena, during the course of investigations conducted in 2017. The investigations included prospecting, terrain mapping and sampling, followed by assessment of data collected in situ and from laboratory analyses. The hyperalkaline spring is of the ascending type, its yield is very low (~0.05 L/s), and the water emerges in a diffuse fashion along fractures. The spring water is of the Ca-OH type, the pH level is 11.6 and the water temperature 11.2°C. The drainage area of the spring, like the entire Mt. Studena, is built up of Paleozoic ultramafic rocks, which geotectonically belong to the External Vardar Subzone. The spring is situated in the floodplain of the Brezanska River, whose channel is the local base level of erosion. The primary point of groundwater emergence is in solid ultramafic rocks, within a zone of fractures up to 0.5 mm wide, over a land area of ~1.5 m2. The paper describes a conceptual model of the formation of hyperalkaline water for the ascending spring in the ultramafic valley of the Brezanska River, on the northern slopes of Mt. Studena. The pH level of the groundwater is indicative of contemporary serpentinization, deep groundwater circulation and a prolonged contact between groundwater and ultramafic rocks along secondary fracture systems.

AB  - The role of natural attenuation processes in groundwater contamination by petroleum hydrocarbons is of intense scientific and practical interest. This study provides insight into the biodegradation effects in groundwater at a site contaminated by kerosene (jet fuel) in 1993 (Vitanovac, Serbia). Total petroleum hydrocarbons (TPH), hydrochemical indicators (O-2 , NO3-, Mn, Fe, SO42-, HCO3- ), delta C-13 of dissolved inorganic carbon (DIC), and other parameters were measured to demonstrate biodegradation effects in groundwater at the contaminated site. Due to different biodegradation mechanisms, the zone of the lowest concentrations of electron acceptors and the zone of the highest concentrations of metabolic products of biodegradation overlap. Based on the analysis of redox-sensitive compounds in groundwater samples, redox processes ranged from strictly anoxic (methanogenesis) to oxic (oxygen reduction) within a short distance. The dependence of groundwater redox conditions on the distance from the source of contamination was observed. delta C-13 values of DIC ranged from -15.83 to -2.75 parts per thousand, and the most positive values correspond to the zone under anaerobic and methanogenic conditions. Overall, results obtained provide clear evidence on the effects of natural attenuation processes-the activity of biodegradation mechanisms in field conditions.

AB  - Annex to the interpretation of the role of geoenvironment in the formation of extreme discharges of the Rosomačka River provides exact and empirical evidence of the significance and the need for its knowledge. For hydrologically unstudied watercourses, especially for those which do not have continuity of discharges, the knowledge of the role of geoenvironment in the emergence of their extreme discharges contributes to a more realistic response to practical water management issues, protection against adverse effects of waters, defining the ecological aspect of watercourses under the influence of various changes in the near future (climatic, anthropogenic, hydrological), preserving the quality of river water, meeting the requirements of the EU Water Framework Directive 2000. The aim of the paper is to understand better the river systems and their runoffs in the form of high and low waters or complete drying up of hydrologically unstudied but also of hydrologically studied watercourses, and through the representation of the role of geoenvironment. On the concrete example of the Rosomačka River, a hydrologically unstudied watercourse, the significance of geoenvironment in the interpretation of its extreme discharges was emphasized. The contribution of the following elements of geoenvironment of the basin area was analyzed: lithological, neotectonic, hydrogeological and morphological. The research method is based on field research, quantitative geomorphological analysis, systematization and synthesis of the obtained results, as well as the analysis of published papers. Additionally, the contribution is reflected in emphasizing the need for communication between experts of various specialties dealing with hydrographic systems.

AB  - Once released in the environment, petroleum hydrocarbons can be long-term sources of contamination. The main advantage of bioremediation compared to conventional remediation treatments is its reduced cost. Natural attenuation is the passive bioremediation approach that relies on natural processes to reduce contamination. This study provides insight into the natural attenuation processes in groundwater in the alluvial deposits of the Zapadna Morava River (the site of historical contamination by kerosene in Vitanovac, Kraljevo, Serbia). Monitoring was performed in the direction of groundwater flow, downgradient from the source of contamination. Groundwater samples were analyzed for the following parameters: total petroleum hydrocarbons (TPH), O-2, NO3-, Mn, Fe and SO42-. TPH concentrations declined in groundwater across the site, and were accompanied by increasing concentrations of electron acceptors (O-2, NO3-, SO42-) and decreasing concentrations of metabolic products of biodegradation (Mn, Fe). The observed trends provide strong evidence of the activity of different biodegradation mechanisms at this site (aerobic respiration, nitrate reduction, reduction of manganese (IV), reduction of iron (III) and sulfate reduction). The results obtained confirm the natural occurrence of aerobic and anaerobic biodegradation mechanisms in this phreatic aquifer contaminated by petroleum hydrocarbons 20 years ago. However, use of natural attenuation as a cost-effective remediation alternative depends on its capacity to ensure protection of public health, safety and the environment.

The observed trends provide strong evidence of the activity of different biodegradation mechanisms at this site (aerobic respiration, nitrate reduction, reduction of manganese (IV), reduction of iron (III) and sulfate reduction). The results obtained confirm the natural occurrence of aerobic and anaerobic biodegradation mechanisms in this phreatic aquifer contaminated by petroleum hydrocarbons 20 years ago. However, use of natural attenuation as a cost-effective remediation alternative depends on its capacity to ensure protection of public health, safety and the environment.",

AB  - The objective of this study was to stimulate microbial biodegradation of petroleum pollution in groundwater and to analyze changes in the abundance and distribution of organic compounds detectable in petroleum. Bioremediation was conducted in a closed bipolar system, by bioaugmentation with consortia of hydrocarbon degrading microorganisms (HD) and biostimulation with nutrients. Comprehensive twodimensional gas chromatography-mass spectrometry (GC X GC-MS) was used to visualize all fractions simultaneously. During the study, the content of total petroleum hydrocarbon (TPH) in groundwater decreased by 92.7% of the initial level, and the average rate of biodegradation was 0.1 mg/L per day. Increased numbers of HD were observed and the dominant genera were Pseudomonas, Rhodococcus, Achromobacter, Bacillus, and Micromonospora. In the first 30 days of bioremediation, there was no significant biodegradation of n-alkanes and petroleum biomarkers - isoprenoids such as pristane and phytane, and polycyclic-saturated hydrocarbons such as terpanes and steranes. However, after 60 days of bioremediation, more than 95% of n-alkanes, terpanes and steranes were biodegraded. Phenanthrene and its methyl-,dimethyl-, and trimethyl-isomers were biodegraded and reduced by more than 99% of their initial levels. However, their decomposition had clearly commenced after just 30 days. This is a somewhat surprising result since it follows that the phenanthrenes were more susceptible to biodegradation than the n-alkanes and isoprenoids. Depending on the microbial community used for bioaugmentation, biodegradation of phenanthrene can precede biodegradation of saturated hydrocarbons.

AB  - This study provides insight into the enhanced in situ bioremediation applied for remediation of groundwater contaminated by petroleum hydrocarbons. Activities prior to the application of this remediation approach included removal of the source of groundwater contamination-an underground storage tank and contaminated sediments-from the unsaturated zone. The hydraulic feasibility of this remediation approach was proved by hydraulic conductivity characterization of the site. Enhanced in situ bioremediation was performed by a combination of biostimulation and bioaugmentation within the closed bipolar system (one extraction and two injection wells). Biostimulation was conducted by addition of nutrients, and stimulation of oxidation processes by injection of H2O2, into the aquifer. Bioaugmentation/re-inoculation was achieved by injection of a zymogenous consortium of hydrocarbon degrading microorganisms isolated from the contaminated groundwater. The average extraction capacity was 0.5 l/s, with an average injection capacity of 0.25 l/s per well. The efficiency of the remediation approach was measured by changes in the content of total petroleum hydrocarbon (TPH), total chemoorganoheterotrophic (TC) and hydrocarbon degrading (HD) microorganisms. After biostimulation and bioaugmentation, the number of TC and HD microorganisms started to increase. This was followed by a decrease of TPH concentration in the groundwater from an initial 6.8-0.5 mg/l at the end of the bioremediation. The applied remediation approach was highly efficient and very effective in reducing TPH to acceptable levels. Together, these facts provide strong evidence of its potential for remediation of groundwater contaminated by petroleum hydrocarbons.

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.

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.
