Project details

Short description

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.
