Analysis of groundwater from deep boreholes in Kraakemaala, Sternoe and Finnsjoen

Groundwater from deep boreholes in granitic rock at three different sites in Sweden - Finnsjoen, Kraakemaala and Sternoe - has been sampled and analysed. A total of ten different boreholes have been sampled; one at Kraakemaala, two at Sternoe and seven at Finnsjoen. In general four levels per hole containing waterbearing fractures have been selected. Prior to sampling, a water-bearing level is isolated between packer sleeves. The deepest levels are down to about 500 m. The sampling was carried out by the Geological Survey of Sweden and a number of laboratories have participated in the water analyses. The present report is a presentation of the results of the groundwater analyses. The reliability of the results is discussesd but there is no evaluation in relation to geology and hydrogeology. This report will present the basic results from the groundwater analyses to be further evaluated by experts in different fields. (author)
