Assessing effectiveness of groundwater remediation technologies to a coastal aquifer within an urban environment in South Africa

Abstract

The study aimed to assess the effectiveness of Reverse Osmosis technology as an example of ex-situ groundwater remediation technologies. The Cape Flats Aquifer System, an urban coastal system, was used as a case study. Globally, urban groundwater contamination remains a known problem for water users, hence the need to remediate such water. The study argues that effective technologies such as Reverse Osmosis to remediate groundwater contaminants exist. However, the effectiveness of such technologies is not demonstrated to inform the wider application. The question of how effective these technologies are in remediating groundwater contaminants is not fully understood.
