Kirsten Raible is a Hydrogeologist at Umvoto and holds an MSc in Engineering and Environmental Geology, specialising in Hydrogeology, from the University of Pretoria. Her Master’s research investigated the hydrochemistry, hydrogen and oxygen isotopes, and radon in surface water and groundwater within the Timbavati catchment, South Africa. The study highlighted contrasts between groundwater and surface water chemistry and isotopic signatures, identified links between land use and nitrate contamination, and assessed radon variability across aquifers.
At Umvoto, Kirsten has contributed to the refinement of South Africa’s Strategic Groundwater Source Areas (SWSA-gw). Her fieldwork includes groundwater monitoring programmes through water quality sampling, groundwater-level measurements, and borehole rehabilitation and drilling supervision. She also undertakes hydrogeological data analysis, GIS work, and technical reporting as part of project deliverables. She is registered as a Candidate Natural Scientist with SACNASP.
Outside of work, Kirsten enjoys hiking, practicing Historical European Martial Arts (HEMA), and playing Dungeons and Dragons. She also volunteers at TEARS Animal Rescue on weekends.
