- Abstract
- This paper addresses the general overview of 2D mathematical models both for inorganic and organic contaminants moving in an aquifer, taking into consideration the most important processes that occur in a ground. These processes impact in different extent on the concentration reduction values for the moving contaminants 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 denitrification) and radioactive decay (for moving radionuclides). Based on this 2D contaminant transport models it has been possible to calculate numerically the dimensionless concentration values with and without all the chosen processes in relation both to 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concentration values to the measured concentration ones (in the chosen earlier piezometers) in relation both to the new unpublished measurement series of May 1982 and to the new set of parameters used in these 2D contaminant transport models.
