Oil was discovered in what would become South Sudan in 1979. Production commenced in 1993. From the very outset there were concerns about the oil companies’ adherence to the environmental standards imposed on the disposal of the processed water ensuing from their pumping operations. Indigenous people consuming water taken from wells located in the catchment areas of the oil rigs began arriving at local clinics. The peoples’ health complaints ranged from nausea and skin problems to neurological disorders. The villagers also reported that the water in their wells had become salty, that it stank, and that their livestock and plants were ailing, even dying after having consumed it. In the early 2000s, local residents resisted their forced expulsion from their lands by oil companies and their governmental allies. South Sudan was recently ranked as the most dangerous country in the world for humanitarian workers - due to the world's highest rate of fatalities and other grave incidents. This comes with the assassination of a number of journalists who were striving to report on the links between Big Oil and the South Sudanese government.
