A comparative study of the PAH contents of the aquifers in the six main geological formations in Belgium was carried out and related to the organic carbon. Although PAH-values were very low, the highest mean values were observed in the Carboniferous limestone of Namur and Condroz, in the Neogene Sands of Campine and in some galery-type catchments. It was however not possible to evaluate fluctuations in time within a single catchment or between different catchments in the same aquifer. On the other hand, no relationship was found between PAH- and TOC-values. |
