The National Oceanic and Atmospheric Administration (NOAA) has estimated the BP oil leak(s) to be about 210,000 gallons or about 5,000 barrels of oil a day.

But recently BP officials told investigators the oil could be rushing out much faster — at a rate of 2.5 million gallons a day — and further, there’s no way to really tell, for sure, how much is oozing into gulf waters.

If the oil is leaking at the worst-case rate of 2.5 million gallons a day, it would have already spilled 52 million gallons of oil into the gulf — nearly five times what was dumped by the Exxon Valdez in 1989, known as the worst U.S. oil spill.

In other words, the BP spill would already BE the worst oil spill in U.S. history.
