How to Clean Up the Oil: Lessons that Amoco and Exxon Didn’t Learn

RP Siegel | Friday May 14th, 2010 | 17 Comments

In 1978, the oil tanker Amoco-Cadiz broke up off the coast of France, dumping 220,000 tons of heavy crude oil into the Atlantic. The spill was so large that the entire Brittany coast was impacted. Because of the tremendous costs involved, only selected sections were treated with detergents and dispersants. Ecological studies five years later showed that the untreated areas had fully recovered. But, the areas that were treated have still not recovered  32 years later. How could this be?

Oil is a naturally occurring material. It is not uncommon for oil to seep up from cracks in the ocean floor. According to Terry Hazen, a PhD micro-biologist working on bioremediation in the Earth Sciences division of the DOE’s Lawrence Berkeley Laboratory, there are thousands of varieties of petroleum-degrading bacteria  who are happy to feast on the oil and break it down into simpler and generally safer compounds. Whenever an oil spill occurs, local concentrations of these bacteria are seen to increase up to 100,000 fold.

That means that if the oil is contained and remains at sea, eventually it will be broken down. That’s an important point to keep in mind.

Eleven years after the Amoco-Cadiz, there was the Exxon Valdez incident which resulted in 11 million gallons of heavy crude entering Prince William Sound and despoiling 1300 miles of pristine coastline. ExxonMobil has spent over $7 billion to date on the cleanup with relatively little to show for it. Crews attempted bioremediation there,  providing fertilizer to encourage the bacteria to grow. Some of the oil was broken down that way, though side effects, such as eutrophication, where the water becomes oxygen depleted and unable to support life, were significant. This effect is also responsible for numerous dead zones already existing in the Gulf of Mexico, the result of fertilizer-laden water coming down the Mississippi River as it passes through the Midwestern farm belt. Hazen is concerned that these dead zones may become significantly larger as the result of the recent spill because of the bacterial growth that will inevitably occur.

This is not to say that nothing that should be done. But the options are few and many of them, such as burning or the use of toxic dispersal agents can create as much or more harm than they are trying to prevent. Unfortunately, urgency and prudence don’t seem to mix any better than oil and water do.

According to Riki Ott,  marine toxicologist and author of “Not One Drop: Betrayal and Courage in the the Wake of the Exxon Valdez Oil Spill,”  spraying Corexit 9527A (which contains 2-Butoxyethanol) in the Gulf, as BP is currently doing, in an attempt to minimize damage to the coast, will kill the shrimp eggs and larvae and young fish that are in the water column now. The chemicals in them can linger in the water for decades, especially when used in deep water, where low temperatures can inhibit bio-degradation.  The use of this chemical was responsible for the collapse of the herring fishery in Alaska after the Exxon Valdez. What is so counterproductive about this is the fact that this chemical will also kill the very micro-organisms that would otherwise naturally break down the oil. Ott’s biggest concern is the “young of the year,” the eggs and embryos and very young fish who are so much more sensitive to these chemicals. “There will be a delayed reaction,” she said, “when these fish don’t show up as adults when they’re supposed to.”

Terry Hazen feels that chemical dispersants should only be used, if at all, in a lesser-of-two-evils scenario, where their use might keep the oil from reaching particularly fragile areas or those harboring endangered species. According to Hazen, the most effective and the safest things we can do are to try to prevent the oil from coming ashore and damaging wetlands by erecting barriers and then physically mopping up as much as the oil as we can get our hands on.  But where can we possibly find a mop that big?

It turns out that a number of interesting ideas have been proposed, including the use of human hair and cotton gin waste. But by far the most compelling idea I’ve heard about comes from a Michigan woman named Adria Brown. Brown’s company, Recovery I Inc., has developed and patented a product called Golden Retriever that is designed to recover oil from water. It is  made from corn cobs. Corn cobs turn out to be especially effective in this task, due to the fact that they are buoyant, and the fact that they tend to spin in moving water, which exposes their entire surface to the oil which clings readily to it. The absorption occurs quickly, and once adhered to, the cob will remain afloat without leaching, for over 24 hours allowing plenty of time for retrieval using skimmers. As an added benefit, the oil can be completely recovered by centrifuge and the cobs can be reused. Brown has been working with an extensive farm network across the Midwest, led by Feeders Grain and Supply of Corning, Iowa, to acquire the needed materials in quantity. Together, they have amassed a stockpile of close to 34,000 tons of material that is ready to be deployed to the Gulf, where it can be administered using barges, that is, as soon as someone down there asks for it. Sen. Chuck Grassley has also been involved, helping to move the paperwork in Washington.

Where will the manpower come from? How about the thousands of fishermen who are now out of work and are willing to do anything they can to save their livelihood? How about paying them instead of paying expensive outside consultants with their exotic chemical cocktails? According to Ott, who was on location in Lafayette, LA, when I spoke to her, “the people down here are looking for something that is “bayou-degradable.”

We can only hope that the folks in charge of the cleanup will listen to sensible suggestions, rather that continuing to rely on rash measures, in the appearance of “doing something” about the problem.

In the mean time, we will find out in about 75 days if BP’s effort, to drill a second well to release the pressure will work. By that time more than twice the oil that came out of the Exxon Valdez will have entered the Gulf waters.

It is very difficult to find any kind of silver lining in this story. All we can hope for is that the damage can be contained to the extent possible and that maybe all Americans will stop and reconsider the impact that our way of life is having on the planet that sustains us. I know, for me personally, every time I get in my car and drive somewhere, I imagine a few drops of oil being added to the Gulf of Mexico in my name.

    Sometimes the simplest solutions to the biggest problems in life have always been there right in front of us–I live in Fairfield Iowa's Abundance Ecovillage right in the middle of corn country. Thank you for suggesting Adria's solution. I will spread your article around the web.

      thinks this is a bettee option and cleaner and puts people back to work and protect our beadhes BP seems to continuely failing I like this idea then a fut fluff and haiy option! why waw this not used????
      seems goverment wants to spened more money and keeo this disaster around! waht up here? whats the real desl is the other guy in goverment pocket and it to slow up recovery how di we make people of the gains versus there hair an fluf an stuff?

    Thanks God someone is suggesting some cleaner ways How to Clean Up the Oil Spill http://bit.ly/9jEyX1

  • Lance Stokes, Ph.D.

    Adria Brown;s Recovery I “Golden Retriever” will work and certainly deserves an opportunity to be fully demonstrated in the Gulf. I am an environmental engineer also from Michigan and became away of her technology about 10 years ago. She has all the corn in Iowa behind her. How do we get BP to wake up and give this process a try?

    Hi

    Diatom Algae can provide the oxygen required by bacteria that breakdown the oil.
    Diatoms give huge amounts of oxygen and are also the natural food for fish.
    Diatoms do not cause eutrophication, unlike Blue Green Algae.
    In fact, Diatoms are a solution to eutrophication and we are proposing them as a solution to dead zones.

    We cause a bloom of Diatoms using our patented nano silica micro nutrient powder – NUALGI.

    I just called BP here
    “Do you have ideas to help us?:
    +1 281 366 5511″
    and suggested Golden Retriever. Call them too! Tell a friend!

  • fotoman

    Brilliant article, Mr. Siegel, raising issues of whether the attempted cure is worse than doing nothing, and introducing the notion of absorbent corn cobs. Let's all hope creativity and brilliance conquer the day with this horrible problem!

  • RP Siegel

    When you contact BP, be sure to mention the company, Recovery I (that's Roman numeral one), which is located in MIchigan. Their website is http://recoveryiinc.net/index.html

  • Cathy Shaughnessy

    Brilliant and thank you Adria!! Lets pass this on to BP and all the brains out there trying to figure this one out. The link is http://recoveryiinc.net/index.html

    I sell an all natural Cotton absorbent remediation product used extensively in Texas in the oil and gas industry. This product also works tremendously on water–repels water just absorbs oil, won't release oil, floats for prolonged time and contains live microbes which remediate (eat) the oil, and will not harm environment or wildlife. It's called Clean b-sorbent it's an unbelievable fix and very economical as it absorbs 6-8 times its weight. I've had spent weeks making contacts to local governments, EPA, BP etc. all to no avail. This product also works as effectively on land. There are some factors to consider, however, with this spill happening in the gulf. As the oil is “churned” in the water it becomes emulsified and sunlight etc changes the oil's properties. It isn't like a simple oil slick sitting on top of water. This causes some issues in some of these natural absorbents actually getting the job done.

      I just searched on Google for the product name that you mentioned (“Clean b-sorbent” using quotes) and found no results. That may be the reason why nobody is responding to your attempts to contact local governments, EPA, BP. Do you have a website on which this product is mentioned?

    • Peter

      A quick search got this company info for people to consider.
      I hope we all support the (natural) cleanup effort with a will to succeed.
      Petition B.P. (Big Problem) to cease & desist use of chemical dispersants,
      there are untold V.O.C.'s emanating from the flowing oil stream.
      Look up:
      Hydrogen Sulfide – EPA safe Maximum = 5-10 PPM. Tested level @ 1200 PPM
      Benzine – EPA safe Max = 0-4 Parts Per Billion. Tested @ 3000 PPB
      Methelene Chloride -EPA Safe Max = 60 PPB. Tested @ 3000 – 4000 PPB

    corn cob has been used for years as a means of removing oils from all types of parts
    why not from water.

    The best solution is to use EM: Effective Micro-organism. They can help solve this problem on a nature way. EM increase the diversity of micro-organism. Without micro-organism no live is possible. We don't see this little creatures but there are important for ALL the live on earth. Sea also http://www.teraganix.com/Effective_Microorganis

    i've thought of a simple and cheap separator tube that can be integrated in any boat or ship. have a look at http://autodelusion.com/oil-spill/ for a schematic on how it can be done. It basically uses a submerged tube to allow oil to float above the water, and the weight of the oil pushes the water away back into the sea.
