Oil Spill Eater International (OSEI), through the Gulf Oil Spill Remediation Conference group, issued a press release this week saying that the U.S. Environmental Protection Agency (EPA) effectively blocked or otherwise delayed scientific advancement in the cleanup of the 2010 Gulf of Mexico oil disaster by refusing to acknowledge the toxicity of the oil dispersant Corexit.
According to OSEI, the EPA is guilty of violations to the Clean Water Act because they knowingly used the toxic dispersant instead of opting for cleaner, less toxic methods of oil spill cleanup.
OSEI is actually not off base with their accusations. Reports from late 2012 revealed that using oil dispersants like Corexit make oil spills less visible, but when combined with the oil, create a mixture that is 52 times more toxic than the oil itself. The studies revealed that even in small amounts, the combination of oil and Corexit reduced the number of egg hatchings in small marine invertebrates by 50%. These are small creatures like krill, shrimp, and other crustaceans that form the bottom of the oceanic food pyramid.
Those results were just from small doses of the mixture. And as I wrote in 2011, the amount of Corexit dumped into the Gulf was anything but “small”:
