Abstract
The investigations have been grouped to several geometric scales under the disciplines of geology, geohydrology and groundwater chemistry, transport of solutes and mechanical stability. Geological mapping and geophysical measurements have been made both on a regional and on a site scale. On the site scale additional surface measurements, drilling of 35 percussion boreholes and 19 cored boreholes was made. The results of the geological investigations show that the Aespoe bedrock is a complex mixture between Smaaland granite, Aespoe diorite and fine grained granite. Hydraulic and chemical data was collected from existing well records within the Kalmar County. Hydraulic conductivity measurement and interference pumping tests were made in the core drilled holes and to some extent in the percussion holes. The hydraulic conductors are basically the fracture zones, but one of the most important is a NNW striking system of single fractures which is difficult to distinguish geologically. The chemical conditions of the groundwater and the fracture minerals form water bearing sections of the core drilled holes have been examined. Water samples were collected from percussion boreholes. The groundwater can be divided into three categories. Fresh water down to approximately 50 m depth. Mixed fresh and seawater 50-100 m, present and/or

These models are the basis for calculation of the ambient groundwater situation and the way in which the hydrological regime will change during the excavation of the laboratory. In order to allow for different levels of detail the conceptual models are established on different scales. The geometrical scales chosen are 500 m, 50 m and 5 m. (au).}
