Abstract		Contamination of the Ljubljansko Polje aquifer with Cr+6 dating to 1986 is considered to be one of the best-investigated groundwater pollutions in Slovenia. The contamination put a halt to water pumping in one of the wells for water supply in the Kleče pumping station, this being the major pumping field of a municipal water supply company. Chemical analyses of Cr+6 were carried out for almost each groundwater sampling in Ljubljansko Polje aquifer and a large amount of data has been made available. In-depth investigation and pollution modelling was carried out as well as several papers were published on the subject. Furthermore, contamination is a good tracer giving data and information on groundwater flow, hydrodynamics dispersion and leaching of pollution out of the aquifer. The contamination in the most polluted Kleče pumping field is today below the limit of chemical detection. Nowadays, highest degrees of aquifer pollution are identified south of Hrastje pumping station.
