Environmental water risk assessment, management and wetland bioremediation

My research is focused on restoring an abandoned secondary settling pond at Water Hub, Franschhoek, at a site that was previously used as a Waste Water Treatment plant. The aim of the project is to establish methods for enhancing the ecological biodiversity within the wetland. It involves an interdisciplinary approach to exploring the biomimicry of natural processes that have the potential for treating dry sludge following the re-wetting of a large, representative sample. The project will explore various methods including the characterizing of heavy metal in dry sludge; leaching of toxicity after dry-sludge re-wetting; and the aquatic biota response. The project will establish a baseline dataset and an approach to rehabilitate the wetland and establish a biodiverse ecosystem.
