Abstract (in english)
   The north Bohemian Cretaceous area is the location of the most recent uranium ore production in the Czech Republic. It is also the area where the exploration, rpoduction and processing of uranium ores has had the greatest impact on the environment, predominantly due to extensive changes in the groundwater flow regime and quality caused by an incompatible combination of in situ leaching (ISL) technology and classical deep mining. The ISL technology involved using sulphuric acid as the prime leaching agent, as well as other chemical agents in the leaching process. This in turn has led to the presence of huge amounts of contaminated groundwater in the sedimentary aquifers of the north Bohemian Cretaceous, forming a potential menace to the high-quality drinking water resources of the area.
   The paper describes the pollution mechanisms resulting from the mining methods and details the different approaches used for remediating the groundwater and for protecting those parts of the aquifers that are not yet polluted. It also gives information about the regulations and legal aspects concerning the closure and dismantling of the uranium mines
