Dr Jo Barnes, Senior Lecturer Emeritus at Stellenbosch University, speaks to Lester Kiewit about Cape Town’s ongoing water contamination challenges. Drawing on new peer-reviewed research, she explains how “contaminant denialism” — including withholding data, misrepresenting science, and ignoring water flow dynamics — has hindered transparency and public health protections. The conversation explores the impact of outdated infrastructure, political and economic pressures, and the urgent need for independent oversight and predictive modeling to improve water quality management. This research sheds light on a decade-long dispute between scientific evidence and official public communication in Cape Town.
