Oil Eating Bacteria

The good news is that newly discovered bacteria biodegrade oil in the oceans, and have been chowing down on the oil spilled from the Deepwater Horizon  (Earth and Sky, NPR, PBS, SFGATE) and from oil seeps for millions of years.

While it’s unexpected and wonderful that bacteria are biodegrading the oil, is begs the question:

Do we want to fill the seas with oil and oil-eating bacteria or oceans of clean water, coral, oysters, fish, turtles, and dolphins?

And how quickly can they consume the 5.1 million barrels that gushed into the Gulf at a rate of 60,000 barrels per day for 85 days begining April 20, continuing thru May and June, and ending July 15, 2011?

I suspect it will take more than a few weeks, months, or years.

And do those bacteria break down dispersants?

John Ehrenfeld defines “Sustainability” as “Flourishing.” Because they are small and short-lived, shrimp can handle a higher level of toxics than say dolphins, turtles, etc. We will know the Gulf is clean when there are flourishing populations of dolphins, turtles, and larger and longer-lived fauna, and when they have lower concentrations of heavy metals and petrochemicals in their tissues.

Wendell Berry, in Home Economics, copyright (c) 1987, (here, here) wrote,

To call the unknown by its right name, ‘mystery,’ is to suggest that we had better respect the possibility of a larger, unseen pattern that can be damaged or destroyed and, with it, the smaller patterns.

If we are up against mystery, then we dare act only on the most modest assumptions.  The modern scientific program has held that we must act on the basis of knowledge, which, because its effects are so manifestly large, we have assumed to be ample. But if we are up against mystery, then knowledge is relatively small, and the ancient program is the right one. Act on the basis of ignorance. Acting on the basis of ignorance, paradoxically, requires one to know things, remember things – for instance, that failure is possible, that error is possible, that second chances are desirable (so don’t risk everything on the first chance), and so on.”

Both the Greeks and the Hebrews told us to watch out for the humans who assume that they make all the patterns.

This article is a postscript to the Popular Logistics series on the Deepwater Horizon / Macondo oil well disaster. This began with Earth Day for the Future, April 23, 2010,  and concluded that “The handling of the Deepwater Horizon catastrophe is a textbook study of how not to manage a crisis. The government and the Obama Administration appear to have understated the problem and ceded responsibility to BP, which seems to have acted to protect the Macondo oil field rather than the Gulf of Mexico and the Gulf Coast.” This is borne out by the analysis of the government’s commission on the crisis, covered by NPR here and here.

Oil and Oceans Don't Mix. From Mining News.

“If oil gushes into the Gulf of Mexico at a rate of 60,000 barrels per day, and it takes 84 days to achieve a capability of “process” the spilled oil at a rate of 30,000 barrels per day, how long does it take to “process” the spilled oil?”

It takes two days to process each day’s gushed oil. So the answer is “2N + 188” where “N” equals the number of days oil gushes into the Gulf beyond the 84 days it took to achieve a processing capability of 30,000 barrels a day. If BP or the government stops the spill effective July 15, 2010, then they will process the oil spilled into the Gulf of Mexico by January 20, 2011. If they are able to stop the flow of oil by August 1, 2010, then it will be Feb 19, 2011, before the spilled oil is “processed.” (Source of image)

And what exactly do they mean by “Process the spilled oil?”

People cleaning up the spilled oil.

Here’s another problem: “What is the toxicity for people cleaning up, or “processing,” the spilled oil? How much exposure can an average person tolerate? Is BP providing adequate safety gear and instructions? If people working to clean up the spill are reporting “light-headedness” and other symptoms, is that an indication that they have sustained a toxic exposure?” For more details, here is Melissa Taylor’s article, “Doctors call for help protecting Gulf oil spill workers.”
