Spill Alert 18:13(2017)

In the Amazon, oil pipeline spills have contaminated areas of several hectares. Cleanup operations are challenged by the remoteness of the area, high levels of rainfall, and difficult access. Mechanical cleanup and soil remediation were combined to optimize remediation of the area. The treatments included pressure washing and mechanical removal of the contaminated vegetation and EKO/GRID™ treatment to oxidize the remaining soil hydrocarbons. The low energy demand for this innovative system offers possibilities for using alternative energy sources, such as wind or solar power. The cleaning effect is based on an oxidation process initiated by electrokinetic and electro-osmotic principles. Results from field tests in Brazil show that the PAH mass was reduced by 91% during the first 30 days and to undetectable levels after 90 days. https://www.ukspill.org/spillalert/SpillAlert-Edition18.pdf
