The Karoo Groundwater Expert Group (KGEG) focuses on the understanding of Karoo hydrogeology and its application to specific areas in the western, central and eastern Karoo. This current group assists with the assessment of risks and mitigating measures related to possible shale gas development activities.

As of January 2014 the Karoo Groundwater Expert Group comprises the members as shown below:
