This story makes no sense. The government is intimately involved with the tests, and has people in the room where the data is collected — so they don’t need a “report”.
Further, BP has been reporting on the bubbles coming up near the well, it’s in their dailing briefings, and they’ve discussed how they are analyzing it and what it might be.
It is interesting to note however that these stories starting popping up right about the time that they did the testing on the gas sample of the leaking well head bubbles. Do not know what it could mean though. Some one trying to spread a scare story after good news deflated their balloon or someone sensationalizing the bad news story incorrectly.
