In Kyrgyzstan, uranium ore was mined and processed in the region of Mailuu-Suu (100 km NW from Dschalal-Abad) from 1946 to 1968. The resulting waste rock and tailings have been stored together with ore material of inefficient low uranium content in nearby dumps. Altogether, around 3 million m3 waste material (TACIS 2003) with relatively low radioactive inventory has been deposited in morphologic depressions and covered provisionally.
Accordingly, the World Bank implemented a 6.9 mio. $ disaster hazard mitigation project in Mailuu-Suu. In frame of this project, BGR is carrying out the hydrogeological observation with special respect to the planned geotechnical sanitation of the radioactive waste deposits and is building up a long-term groundwater-monitoring in Mailuu-Suu.
The initial stage of the project comprises the definition of the hydrogeological frame and the investigation of the current distribution of contaminants considering the evaluation of physico-chemical and radiological parameters. Subsequently, the risk potential of the different aquifers will be evaluated regarding the planned sanitation actions. The findings represent the basis for conception and construction of a long-term monitoring network.
