Job description

Project description
The thick aeration zone beneath topographic heights (mountain and hillslope areas), comprising variably water-saturated regolith, unconsolidated rock/bedrock and including perched groundwater bodies, are essentially involved in groundwater quality evolution. Yet, due to extremely high technical demands, observation of the aeration zone, its diverse porous media/habitats and transients in fluid/matter transport are only scarcely investigated. In situ-sampling of fluids, percolating water, mobile inventory, and gases in the aeration (vadose) zone always requires invasive access and entails exposure to artificial collection components and disturbed ambient conditions. That generally involves multiple initial and persistent sources for contamination and artefacts. Especially, if sampling of mobile particulates or gases are in focus, drilling procedures and sampling devices are necessarily custom-made for local properties of weathered rock and call for measures to minimize erosion and fouling. This PhD project is dedicated to the optimization of observational techniques to monitor aeration zone fluids and inventory at different sites in Thuringia. Field work comprises geophysical sounding, joint application of a rotary drilling rig, extensive sampling/monitoring campaigns including experimental optimization and hydrogeochemical analysis.
