The article describes an experiment involving pumping of groundwater from specific sections of the aquifer with a packer. The aim of the experiment was to identify the vertical differentiation of groundwater chemistry of the Wielkopolska Buried Valley Aquifer near Joanka well-field in order to explain the reasons for the occurrence of "brown water”. The research shows significant vertical and horizontal differences in groundwater chemistry. It has been found that “brown water” occurs in the lower part of the aquifer and its chemistry and isotopic composition imply origin from the Tertiary aquifer. It has been proved that the flow of “brown water” from Tertiary aquifer to the Wielkopolska Buried Valley Aquifer is possible through the old wrongly constructed well which was build before World War II. The hydrochemical data have been used to calibrate groundwater flow and contaminant transport model. This model has been used to determine the prognosis of “brown water” migration during well-field exploitation.

This article presents a review of groundwater numerical modeling use for hydrogeological research in Poland. The main source of information were book series of “Contemporary Problems of Hydrogeology” published since 1980 and the articles from first Conference: “Ground Water Flow Modeling” held in 2004 in Wroclaw. The following issues were analyzed in the review: software package, types of discretization network of the percolation space, as well as the main goals and results of numerical modeling. Based on the literature review common software, practical implementation and discretization ways of studied areas were presented. The lack of publication describing modeling research of transient groundwater flow in regional scale was emphasized.
