title = "Spatial visualisation method for hydrogeochemical data – case: Olkiluoto geochemistry",
abstract = "In the long-term safety assessment of a final repository, hydrogeochemistry is one of the principal evaluation tools. Posiva Oy excavates in Olkiluoto, Finland an underground research laboratory (ONKALO) for enhancing the current geoscientific understanding of the site. The need to study the hydrogeochemical features is not inevitable only in the stable undisturbed (pre-excavational) conditions but also in the disturbed system caused by the construction activities and open-tunnel conditions of the ONKALO. The 3-D approach is based on integrating the independently and separately developed and interpreted structural model and the results from the geochemical mixing calculations of the groundwater samples. The core procedure of the method is implemented in an undisturbed conditions by using a linear regression. The 3-D method is not only a tool for visualising the hydrogeochemical conditions but also a tool for estimating the possible groundwater sample characteristics at any arbitrary point.",
