Technique to Stop Underground Water Pollution by Crude Oil?
Is there an underground technique that can stop underground water pollution by crude oil such as those in:The oil-rich Niger Delta suffers from extensive petroleum contamination. A pilot study was conducted in the region of Ogoniland where one community, Ogale, has drinking water wells highly contaminated with a refined oil product. In a 2011 study, the United Nations Environment Programme (UNEP) sampled Ogale drinking water wells and detected numerous petroleum hydrocarbons, including benzene at concentrations as much as 1800 times higher than the USEPA drinking water standard. UNEP recommended immediate provision of clean drinking water, medical surveillance, and a prospective cohort study. Although the Nigerian government has provided emergency drinking water, other UNEP recommendations have not been implemented. We aimed to follow up on UNEP recommendations by investigating health symptoms associated with exposure to contaminated waterassess the adequacy and utilization of the government-supplied emergency drinking water.
