Is dispersant still being sprayed in the gulf?

Kari Huus writes: This photo and laboratory tests indicating that this foamy substance is dispersed oil have raised questions about the government’s assurances that the toxic chemical was not sprayed after the Deepwater Horizon well was capped.

Kari Huus writes:The use of chemical dispersants in the wake of the massive BP oil spill ended on July 15, when the broken Deepwater Horizon well was capped, with only one exception four days later, according to federal agencies. But photos and chemical lab results obtained by msnbc.com suggest that the controversial chemicals have been sprayed much more recently than that.
