A major new independent scientific assessment, carried out by the United Nations Environment Programme (UNEP), shows that pollution from over 50 years of oil operations in the region has penetrated further and deeper than many may have supposed. The assessment has been unprecedented. Over a 14-month period, the UNEP team examined more than 200 locations, surveyed 122 kilometers of pipeline rights of way, reviewed more than 5,000 medical records and engaged over 23,000 people at local community meetings. The environmental restoration of Ogoniland could prove to be the world's most wide-ranging and long term oil clean-up exercise ever undertaken if contaminated drinking water, land, creeks and important ecosystems such as mangroves are to be brought back to full, productive health. The report key findings are alarming both in terms of human health protection and environmental protection.
