BP now using EIGHT types of chemical dispersants in Gulf
Large-scale skimmer begins testing in Gulf, CNN, July 4, 2010:
Meanwhile, Environmental Protection Agency scientists… [are doing] toxicity testing on eight of the dispersants used in the Gulf. …
[T]he agency has said it plans to conduct more tests of the toxicity of the dispersant when mixed with crude.
A CNN analysis of daily dispersant reports provided by the Deepwater Horizon Unified Command showed that the chemical dispersants keep flowing into the Gulf of Mexico at virtually unchanged levels despite the EPA’s May 26 order to BP to “significantly” scale back.
Before that date, BP used 25,689 gallons a day of Corexit. Since then, CNN’s analysis showed, the daily average of dispersant use has dropped to 23,250 gallons a day, a 9 percent decline.
