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  - 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  - 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.

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.

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  - Disertacija se konceptualno sastoji iz dva dela kojima je obuhvaćen pasivan (prirodno prečišćavanje) i aktivan remedijacioni pristup (stimulisana bioremedijacija) kod podzemnih voda zagađenih naftnim ugljovodonicima. U prvom delu disertacije prikazani su rezultati osmatranja procesa prirodnog prečišćavanja u podzemnim vodama na lokaciji istorijskog zagađenja kerozinom. Tragovi zagađenja naftnim ugljovodonicima pronađeni su 20 godina nakon prosipanja kerozina. Ovo je stvorilo osnovu za proučavanje efekata dugotrajne izloženosti podzemnih voda procesima biodegradacije u terenskim uslovima. Uočeno je da se snižene koncentracije elektron akceptora (O2, NO3 -, SO4 2-) i povišene koncentracije metaboličkih produkata biodegradacije (Mn, Fe) poklapaju sa najvišim vrednostima parametara organskog zagađenja u podzemnim vodama (Total Organic Carbon - TOC, Total Petroleum Hydrocarbons - TPH). Utvrđen je uticaj aerobne respiracije, redukcije nitrata, redukcije mangana (IV), redukcije gvožđa (III) i redukcije sulfata na hemijski sastav podzemnih voda. Uticaj metanogeneze je utvrđen na osnovu promena u izotopskom sastavu podzemnih voda, koncentracije δ13CDIC su za oko 12 ‰ više u zoni pod uticajem biodegradacije u odnosu na ostatak područja istraživanja. Registrovano zagađenje podzemnih voda ne potiče od aromatičnih jedinjenja (benzena, toluena, etilbenzena, ksilena - BTEX i stirena), već od zasićenih ugljovodonika. Redukcija sulfata kao pojedinačni mehanizam poseduje najveći pojedinačni kapacitet za biodegradaciju komponenti BTEX. Najvišim koncentracijama TOC odgovaraju višestruko povišene koncentracije Al i SiO2 u zoni povišene kiselosti pod uticajem biodegradacije naftnih ugljovodonika. Pretpostavljeno je da je dugotrajna izloženost intenzivnim procesima biodegradacije ubrzala rastvaranje silikatnih minerala u vodonosnoj sredini...
AB  - This dissertation consists of two parts, a passive (natural attenuation) and an active remediation approach (enhanced bioremediation) for groundwater contaminated by petroleum hydrocarbons. In the first part of this dissertation, results of the monitoring of natural attenuation processes at a site of historical contamination by kerosene are presented. Traces of petroleum hydrocarbon contamination were found 20 years after the kerosene spill. This provided a basis for the monitoring of long term groundwater exposure to biodegradation processes in field conditions. It was observed that decreased electron acceptor concentrations (O2, NO3 -, SO4 2-) and increased concentrations of metabolic biodegradation products (Mn, Fe) corresponded to the highest values of the organic contamination parameters (Total Organic Carbon - TOC, Total Petroleum Hydrocarbons - TPH) in groundwater. The impact of aerobic respiration, nitrate reduction, reduction of manganese (IV), reduction of iron (III) and sulphate reduction on the chemical composition of groundwater was determined. Methanogenesis impact was determined on the basis of the changes in groundwater isotopic composition. δ13CDIC values were 12 ‰ higher in the biodegradation affected zone in comparison to the rest of the study area. The observed contamination of groundwater did not originate from aromatics (benzene, ethylbenzene, xylene, toluene - BTEX and styrene), but from saturated hydrocarbons. Sulfate reduction had the largest single capacity for the biodegradation of BTEX compounds. The highest TOC concentrations corresponded to several times increased concentrations of Al and SiO2 in the zone of elevated acidity affected by biodegradation of petroleum hydrocarbons. It was assumed that long-term exposure to intense biodegradation processes has enhanced the dissolution of silicate minerals from the aquifer...;

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.
