Over the past number of years, reports by scientific and research institutions, industry specialists, regulators
and non-government organizations have raised concerns about radioactive and metal contamination in
areas such as the Wonderfonteinspruit Catchment Area (WCA), resulting mainly from diffuse and direct
pollution from gold and uranium mining over the last one hundred years. The individual and collective
initiatives by the relevant stakeholders to address the mining legacy in areas such as the
Wonderfonteinspruit highlighted the importance of:
High confidence scientific assessments on the extent and significance of environmental impacts.
The optimization of remediation methodologies and programmes to ensure that all actions are
justifiable in terms of as low as reasonably achievable (ALARA) principles.
The importance of a management framework to ensure the effective engagement of all stakeholders.
The aim of this paper is to outline the principles of a framework for intervention and remediation in the WCA
using the precedent set, and lessons learnt, from a previous co-operative exercise by the mining industry, the
National Nuclear Regulator (NNR) and the public, to clean up thirty-eight off-mine sites. It further
incorporates the principles of intervention and a source/pathway/receptor assessment approach.
