Electrical conductivity and water sampling measurements at the Olkiluoto site in Eurajoki, Drillholes OL-KR30 and OL-KR47
Description
Fracture-specific water sampling and electrical conductivity (EC) measurements were performed in drillholes OL-KR30 and OL-KR47 at the Olkiluoto investigation site between November 2008 and May 2009. The measurements were conducted using the Posiva Flow Log, Difference flow method (PFL DIFF) with a new water sampling specific configuration. The purpose of the measurements was to perform field tests with the water sampler and obtain information on the geochemical properties of the groundwater. This report presents the principles of the method and the results of measurements. The measuring programme included water sampling and EC measurements in chosen fractures. In some of the fractures only the fracture-specific EC was measured. Flow and single point resistance (SPR) measurements were performed in order to locate the fractures. During the measurements the fracture flow and the temperature of the flowing water were also monitored. (orig.)
