Ongoing research projects at Stellenbosch University

•    Evaluating aquatic pesticide pollution in the Western Cape
•    Conducting a detailed water balance during the recent drought in the Western Cape
•    Developing a numerical hydrogeological model for municipalities surrounding Cape Town (e.g., Stellenbosch, Paarl) in order to delineate wellhead protection areas.
