# University of Johannesburg professor, Philiswa Nomngongo, is using nanotechnology to detect and remove water pollutants in South Africa. Nanotech offers tools like sensors and membranes to detect and remove toxins. The Department of Water and Sanitation’s 2023 Blue Drop Audit Report found that 46-percent of the country’s water was polluted. Nomngongo’s research is using nanotechnology to identify the problems in different sources, like wastewater or river water. While costs and scalability remain challenges, the technology offers hope for rural access to clean water.
