What sampling method would you use?Abstract: The extract reports that in November 2017, the department of water affairs and sanitation revealed that36 mines operate without water licences, in violation of the National Water Act. They use water and wasteand pollute without being monitored by the department. In five case studies on mines ranging fromplatinum to coal by the Centre for Applied Legal Studies (at the University of the Witwatersrand in 2018found that very little of the social and labour plans mining companies signed up to were implemented.The study found that mining companies have spectacularly failed to build houses, provide childcare andbursaries as well as training. In most cases the companies also did not tell employees and local residentsabout their promised social and labour plan commitments.
