“…In particular, DNAPL often result in serious contamination problems (Pankow & Cherry 1996). The DNAPL are able to penetrate fractures with apertures of only a few micrometres relatively easy (Kueper & McWhorter 1991;Hinsby et al 1996;Pankow & Cherry 1996) and furthermore, due to their high densities, they are able to sink relatively deeply into the aquifers where they may contaminate old groundwaters (Bishop et aL 1993;Lawrence et al 1996;Pankow & Cherry 1996). DNAPL source zones are capable of contaminating very large amounts of groundwater with highly toxic components.…”

Abstract:Modem groundwater that has recharged aquifers within the past 50 a shows the influence of humans globally, either by the presence of small concentrations of environmental tracers or in some cases by severe pollution. This study describes important environmental tracers (e.g. 3H, 85Kr, chlorofluorocarbons, SF6) and contaminants (e.g. NO3-, pesticides, chlorinated solvents) for modem groundwater dating and recognition of human impacts. Some applications of the described tracers in aquifers investigated in the PALAEAUX study are presented in order to illustrate the advance of modem waters in European aquifer systems. The study shows that the location of the modern water interface varies within a range of between c. 10 and c. 100 m in the investigated aquifers due to variations in hydrogeological setting, climate and exploitation of the groundwater resource. The subsurface distribution of the modem water indicators and contaminants demonstrate that the advance of modem groundwaters and the fate of harmful substances in them have important implications for protection and development of the water resources. Contaminants that do not degrade or degrade only very slowly will advance further into the aquifers and may eventually contaminate even deep groundwater systems.
