Abstract

Language:

The objective of this work was to employ a numerical simulator to investigate the behaviour of contaminant plumes at the interface between the Pampeano and Puelche aquifers in the northeast of the Province of Buenos Aires. The influence of the clay layer on the concentration profiles of chloride and chromium VI was analysed. For this purpose, we developed a characteristics finite element procedure to simulate contaminant transport in saturated anisotropic porous media under steady flow conditions. The simulations for chromium included adsorption effects in the model using a linear isotherm. The study of the Puelche aquifer is of great interest due to its extent, water quality, and the large water volumes extracted. Even though it is a semiconfined aquifer, there are important vertical flows between this aquifer and the overlying Pampeano aquifer, allowing chemical pollutants present at the top of the Pampeano aquifer to migrate towards the Puelche aquifer. Numerical models are useful tools to understand and predict transport and chemical reaction processes in groundwater.
