Just before the summer vacations Wei, Haoyu presented his MSc thesis ”Interpretation of geophysical and geochemical data in a 3D geological model construction of a contaminated site” with data from the Alingsås site. Here is a teaser from the abstract. In this thesis work, a refined three-dimensional conceptual model was built up via GeoScene3D, a 3D geological modelling software. The three-dimensional model consists of terrain surface, interpolated bedrock surface, interpolated groundwater surface, soil and groundwater chemistry data, borehole logs, as well as geophysical data. Of them, the geophysical data came from the 2D inversion results of electrical resistivity and induced polarization (DCIP) measurements along four buried horizontal arrays. The DCIP measurements data were collected before the first pilot injection. Through the visualization in GeoScene3D, it can be clearly seen that most halogenated hydrocarbons concentrate on the lower part of the unconsolidated layer, closely situated to the bedrock surface. In the latest set of measurement, the highest tetrachloroethylene concentration body was found nearby the source of leakage. The highest concentration bodies of trichloroethylene and cis-1,2-dichloroethene are situated at the same location with a slight difference in elevation. … The full MSc report you find here.

And here you find the first MSc project within the MIRACHL project, ”Application of ERT and IP for localisation of chlorinated hydrocarbons at a former dry-cleaning facility”, carried out by Jönsson H. and Wiberg A. at the Hagfors site. in 2017
