Introduction and historical background The eastern catchment of the Mooi River, also known as the Wonderfonteinspruit, has been identified in a number of studies as the site of significant radioactive and other pollution, generally attributed to the mining and processing of uraniferous gold ores in the area. With the establishment of West Rand Consolidated in 1887 gold mining reached the Wonderfonteinspruit catchment only one year after the discovery of gold on the Witwatersrand. By 1895 five more gold mines had started operations in the (non-dolomitic) headwater region of the Wonderfonteinspruit as the westernmost part of the West Rand goldfield.
