UnSAT-EIE – Kopplung der Boden-Aquifer-Behandlung und der technischen Injektion und Extraktion zur Verbesserung der Durchmischung an der Schnittstelle zwischen der gesättigten und der ungesättigten Zone

Soil aquifer treatment (SAT) is a type of managed aquifer recharge in which water infiltrates through a deep vadose zone into the aquifer and can be applied to improve the quality of reclaimed water. Engineered Injection and Extraction (EIE) is a remediation technique consisting of injecting and extracting water with a specified sequence in order to enhance mixing processes in the subsurface, such as the mixing between a treatment solution and a contaminant. In this project, we propose to combine soil aquifer treatment with EIE to enhance mixing processes in the unsaturated and saturated zone and thus increase the effectiveness of natural attenuation and consequently improve groundwater quality. The analysis will be done through experimental work at the laboratory scale and numerical modeling, and it will be complemented with field-scale model scenarios.
