A month has passed since the Deepwater Horizon drilling rig exploded and collapsed, killing 11 of its crew and unleashing the oil leak that gushed millions of gallons of crude oil into the Gulf.

BP and U. S. federal agencies have estimated the leak rate as 5,000 barrels (210,000 gallons) a day since April 28, but a video showing oil flowing into the sea where BP has joined a mile-long pipe to the leak showed that BP's estimates for the size of the spill are likely to be wrong. What they are capturing is a small fraction of the total leak.

So there must be much more than 5000 barrels of oil that is leaking per day from that well which is like a big disaster.

Chairman, Carl-Henric Svanberg reported the incident as similar to the Three Mile Island meltdown in Pennsylvania in 1979. Just as that didn't lead to the end of nuclear power, the spill won't put an end to deepwater drilling, he said at a Google Inc. conference in the U. K. this week.

BP and the Government have been using chemical dispersants to break up the slick into droplets that can eventually be consumed by microbes in order to prevent the oil from reaching the shore. Two relief wells are also getting drilled, each aimed at intercepting the damaged well about 13,000 feet (3,962 meters) below the ocean floor, which that may take about three months.

But the chemical dispersants being used to fight it back from these marshes will likely to ripple through many sectors, not just fishing, said Jean-Michel Cousteau, the Environmentalist and documentary filmmaker in Louisiana working on a piece about the spill. And the industry groups and fishermen fear that their customers will question the safety of their product for years in what is one of the nation's most productive fisheries.
