Abstract

We examined seasonal change in physicochemical parameters NH4, NO3, Cl, SO4 2- , Fe2+, Mn and TOC for anoxic alluvial groundwater from the first drainage line at Kovin-Dubovac and Danube water level. To evaluate the results of four year monitoring programme Principal Component Analysis (PCA) and Cluster Analysis (CA) were performed. Principal component analysis (PCA) as a multivariate statistical method was used for data filtering in order to indicate if there is a connection between groundwater chemistry, surface water levels and sampling season. NH4, NO3, Fe2+, Mn, SO4 2- and TOC were chosen as important indicators of nitrogen transformation potential. Cl and Danube levels were included in analysis as indicators of groundwater recharge. Cluster analysis (CA) was applied for grouping the months of groundwater sampling with similar pattern.
