[en] Groundwater from three boreholes in granitic rock at an investigation site in Klipperaas has been sampled and analysed. Water-bearing levels in the boreholes down to the deepest at 777 m were selected. Sensitive parameters such as redox potential, pH, sulphide and oxygen content are measured electrochemically on the flowing water in a system isolated from the air. Water, filter and gas samples are sent to several laboratories for further analysis. The present report is a presentation of the results of the ground-water analyses. The reliability of the results is discussed but there is no evaluation in relation to geology and hydrogeology. This report presents the basic results from the groundwater analyses to be further evaluated by experts in different fields. (orig./PW)
