“…For the exact examination of contamination transport into groundwater a certain number of piezometers were installed nearby the existing ground lagoon 4 (Aniszewski [1], Aniszewski [2]). Referring to (Aniszewski [2]), an illustrative map only of the chosen natural site is presented below in Fig. 1 along with the detailed numeration of the existed and chosen four piezometers.…”

“…This regularity is related even to the similar (but never the same) contaminants moving in ground media (Spitz and Moreno [9], Chiang [3], Javadi and AL-Najjar [4], Weiss and Cozzarelli [12], Kraft et al [7], Aniszewski [1], Taniguchi and Holman [11], Aniszewski [2]). This is connected, among other things, with negative or positive charging of the solid phase of natural soils (as an "anionic" or "cationic" exchange) (Spitz and Moreno [9], Chiang [3], Javadi and AL-Najjar [4], Weiss and Cozzarelli [12], Kraft et al [7], Taniguchi and Holman [11]).…”

“…It should also be noted that in various climatic and ground conditions, physico-chemical and biological properties of moving groundwater differ considerably one from another, impacting on all the major processes (parameters) used in the transport models and presented here. The climatic and ground conditions selected for the presented transport models are described in greater detail by Spitz and Moreno [9], Chiang [3], Weiss and Cozzarelli [12], Kraft et al [7], Aniszewski [1], Taniguchi and Holman [11] and Aniszewski [2].…”

“…2). It should be noticed that such late measurement series of May 1982 was taken intentionally to compare among other things the gradual depletion in time of the adsorption capacity of the same ground being considered in this paper (for both this measurement series of May 1982 and for the earlier one of November 1981 -Aniszewski [1], Aniszewski [2]). Based on the numerically calculated and the measured concentration values, in further analysis the following values were calculated:…”

This paper presents a general overview of 2D mathematical models for both the inorganic and the organic contaminants moving in an aquifer, taking into consideration the most important processes that occur in the ground. These processes affect, to a different extent, the concentration reduction values for the contaminants moving in a groundwater. In this analysis, the following processes have been taken into consideration: reversible physical non-linear adsorption, chemical and biological reactions (as biodegradation/biological denitrifi cation) and radioactive decay (for moving radionuclides). Based on these 2D contaminant transport models it has been possible to calculate numerically the dimensionless concentration values with and without all the chosen processes in relation to both the chosen natural site (piezometers) and the chosen contaminants.In this paper, it has also been possible to compare all the numerically calculated concentration values to the measured concentration ones (in the chosen earlier piezometers) in relation to both the new unpublished measurement series of May 1982 and the new set of parameters used in these 2D contaminant transport models (as practical verifi cation of these models).

“…Mathematical models of microbial processes have been used for experimental interpretation, design, and prediction in recent decades (3,10,20,22,39,48,49,53,56). These processes were very complex to model because there was no way to measure the detailed metabolisms inside the system.…”

bAccurately predicting the interactions between microbial metabolism and the physical subsurface environment is necessary to enhance subsurface energy development, soil and groundwater cleanup, and carbon management. This study was an initial attempt to confirm the metabolic functional roles within an in silico model using environmental proteomic data collected during field experiments. Shotgun global proteomics data collected during a subsurface biostimulation experiment were used to validate a genome-scale metabolic model of Geobacter metallireducens-specifically, the ability of the metabolic model to predict metal reduction, biomass yield, and growth rate under dynamic field conditions. The constraint-based in silico model of G. metallireducens relates an annotated genome sequence to the physiological functions with 697 reactions controlled by 747 enzymecoding genes. Proteomic analysis showed that 180 of the 637 G. metallireducens proteins detected during the 2008 experiment were associated with specific metabolic reactions in the in silico model. When the field-calibrated Fe(III) terminal electron acceptor process reaction in a reactive transport model for the field experiments was replaced with the genome-scale model, the model predicted that the largest metabolic fluxes through the in silico model reactions generally correspond to the highest abundances of proteins that catalyze those reactions. Central metabolism predicted by the model agrees well with protein abundance profiles inferred from proteomic analysis. Model discrepancies with the proteomic data, such as the relatively low abundances of proteins associated with amino acid transport and metabolism, revealed pathways or flux constraints in the in silico model that could be updated to more accurately predict metabolic processes that occur in the subsurface environment. Microbial environments have been engineered for enhanced oil recovery (7,23,29,33,42) and remediation of soil and groundwater contaminated by chlorinated hydrocarbons, metals, and radionuclides (4,24,30,40,47,51,63) in the past 30 years and have recently been studied to manage carbon dioxide (46). Mathematical models of microbial processes have been used for experimental interpretation, design, and prediction in recent decades (3,10,20,22,39,48,49,53,56). These processes were very complex to model because there was no way to measure the detailed metabolisms inside the system. They were usually represented by specific terminal electron acceptor process (TEAP) reactions with fixed stoichiometry throughout the simulation and were traditionally modeled by Monod kinetics. These models are sufficient under nonlimiting conditions of nutrients. However, the kinetic parameters of these models, which were calibrated but not directly measurable, cannot reflect the sophisticated mechanisms developed by microorganisms to adapt to the changing environment through the regulation of metabolic pathways, such as their ability to respond to nutrient gradients and environmental stress (5, 6).With the ad...
