Hydrogeological characterization

Assessment of groundwater status is conducted according to EU Water Framework Directives, including their associated guidelines, increasingly focusing not only on drinking water supply, but also on environmental objectives for associated aquatic and dependent terrestrial ecosystems. Assessments utilize hydrogeological methods of characterization such as geological, geophysical, geochemical, and hydraulic measurements below ground surface. These methods disclose conditions regarding groundwater flow and its quantitative and chemical status, as well as its spatial and temporal evolution and impact on ecosystems.

Core areas include: 

• Borehole logging for evaluation of the physical and chemical characteristics of aquifers and aquitards ("groundwater bodies")
• Level-determined sampling of groundwater in order to analyze groundwater chemistry and age
• Deliniation of saltwater and freshwater boundaries in aquifers
• Groundwater/surface water interaction in streams and lakes
• Establishing the basis for evaluation of the geographical vulnerability of soils to pesticide leaching
• Optimized and integrated monitoring and modelling of groundwater quantity and quality and interaction with aquatic and dependent terrestrial ecosystems
• Remote sensing for estimating spatially distributed hydrological variables at large scale
• Characterization and evaluation of fracture transport in till as well as limestone
• Hydrological investigation of subsurface CO2 deposition (carbon storage) and final subsurface deposition of radioactive waste
