Residents of Ogoniland (pop. 832,000), in Rivers State, Nigeria, are demanding compensation and clean-up of the oil that has polluted water sources and destroyed their livelihoods. A UNEP study  published in August 2011, concluded that the environmental restoration of Ogoniland could take 25 to 30 years and would require an initial investment of US$ 1 billion contributed by the oil industry and the Government.
Communities relying on polluted wells should immediately be provided with adequate sources of drinking water, the UNEP study said. However, three months after the release of the study, only two of the ten communities where drinking water was found to be dangerously contaminated by oil had been provided with safe water, claimed Chris Newsom of Stakeholder Democracy Network.
