They've finally cemented up BP's runaway well (from above with a second relief well plug still to seal it from below). Unfortunately this comes after 220 million gallons of oil slimed the Gulf of Mexico. So what's the effect of a spill 20 times the size of the Exxon Valdez? Apparently not much, if you believe the government's estimates.
The Deepwater Horizon Oil Budget put out by the Department of Interior and National Oceanographic and Atmospheric Administration says one quarter of the total oil naturally evaporated or dissolved. Having spent time in the heat and oil of the Gulf in June and July, and given the volatile compounds in the light crude that was released, I don't have a hard time believing this. Score one for air pollution. They claim 25 percent was burned, skimmed or recovered from the wellhead. Again, having seen the surface burns and the Q-4000 rig flaming off 6,000 barrels a day in July, creating a black column of oily smoke, skipping the middle men (cars and trucks) and putting sooty carbon dioxide right into our already overheated atmosphere, I can almost believe this figure although it would represent the most successful mechanical recovery of spilled oil in history and I know from being there a lot of oily water was counted as recovered oil.
