Subgroup - Site Characterisation DTU Env: GEUS: Orbicon: Ida Damgaard, Camilla Christiansen, Julie Chambon, Mette Broholm, Charlotte Scheutz, (Poul Bjerg) Bertel Nilsson, Knud Erik Klint, Carsten Suhr, Jacob Bælum Nina Tuxen Subjects Geology Objectives Develop a standard site characterisation methodology. Statistical analysis of sand lens distribution and practical approaches. Investigations at several sites to see if the method is working. Activities Excavation to 5 m Observations of gravel pits Drilling Core samples, terrain to regional aquifer (GeoProbe/Bore Rig) Subjects Hydrogeology Objectives Characterisation of effective transport properties of fractured sites. Activities Piezometric investigation Slug tests Pump tests Permeability Groundwater model Water balance Tracertests? Detailed hydraulic conductivity (Waterloo profiler) Subjects Contamination, Processes, Bacteria Objectives Detailed description of contaminant, organic and bacterial distribution in groundwater and matrix. Understanding of all the complex processes and where these takes place. Investigate which microorganisms that are present, as well as their ability to move from permeable layers into the clayey till matrix. Activities Drilling Soil sampling, analysis Water sampling, analysis Fatty Acids Core samples, terrain to regional aquifer (GeoProbe/Bore Rig) MIP Thin sectioning Viable microorganisms (both unsat and sat) DNA (TCE, TCA) RNA, DGGE profiles Subjects Objectives Geology Develop a standard site characterisation methodology.
