South Sudan Residents Protest Oil Facilities David Mono Danga JUBA , SOUTH SUDAN - Residents around South Sudan's Palouch and Melut oil fields in Upper Nile state demonstrated Wednesday for a third consecutive day against environmental pollution caused by the oil companies. The protesters blocked the doors of at least two oil companies and shut down roads and the airstrip in Palouch. Protester Thon Beny Thon, who resides in Palouch, told South Sudan in Focus that oil companies have polluted nearby land with toxic wastewater and chemicals. He also said protesters are accusing the government and oil companies of failing to live up to their commitment to reinvest a portion of oil revenues to improve local infrastructure and clean up the environment. "The residents are supposed to benefit from the oil being produced in their area, it's their right," Thon said. "Since 1997 -- it has been over 20 years now -- oil is being drilled, but there are no good schools, no clean water, no roads, no hospitals and nothing good for the residents." "The environment is contaminated, causing so many health complications," said Thon, who called increased birth defects and miscarriages among local women a result of the pollution. .
