Agricultural and industrial pressures on groundwater resources are evident from the widespread global contamination of aquifers. To mitigate that pressure we rely largely on natural attenuation, the ability of aquifers (via microbial reactions or other retention processes) to breakdown contaminants of concern. That reliance hinges on our ability to predict and monitor a system’s potential for natural attenuation.

The Hydrogeology Research Group seeks to improve the quantification and monitoring of reactive transport processes that govern natural attenuation in groundwater. Specifically, we integrate flow-through experiments in the laboratory and at field sites with reactive transport modeling and use the geophysical method spectral induced polarization (SIP) as a non-invasive tool that enables higher spatial- and temporal-resolution monitoring of reactive processes.


02.09.2022 | New research paper on capturing glyphosate retention in aquifer sediment using spectral induced polarization (SIP). The research highlights the ability SIP to capture solid-bound concentration changes during the transport of glyphosate through natural aquifer sediment and the potential of non-invasive approaches to help advance ionizable organic contaminant (IOC) monitoring approaches.
