Gulf oil spill: Why booms, in short supply, may not save the day
Prices jump for oil-containment booms, as communities scramble to protect their coastlines from the approaching slick from the Gulf oil spill. Moreover, booms are effective only in certain conditions, experts say.
Oil-containment booms are in short supply on the Gulf Coast as communities scramble to protect their coastlines from the approaching slick, but experts warn that booms alone will not stop the wave-borne crude oil from washing ashore.Skip to next paragraph

Regional supplies of boom are sold out, and the cost of renting booms from elsewhere has nearly doubled in the past week, says Todd Duke, a project manager with Resolve Marine who is working with local officials in St. Tammany Parish to protect Lake Pontchartrain, which abuts New Orleans.
“A manufacturer in Florida told me it would take four weeks to fill an order for boom, so I started calling other contactors in the Great Lakes and Caribbean about renting boom,” says Mr. Duke. “Before the spill, it cost $1.10 a foot, now it’s $2 a foot. There’s only so much out there, and the price is starting to go through the roof.”
The cost of absorbent boom, made of polypropylene (which repels water and soaks up oil), has tripled over the past two weeks, says Mitchell Mark of Snee Chemical, a wholesaler of oil-containment products in Harrahan, La. The region's wholesale stocks of boom have been exhausted, he says. "Manufacturers here in Louisana are working as fast as possible to keep up, but it reaches a point where it's impossible to meet demand. Wholesalers like me are looking everywhere for boom now, including China."
Several types of boom are used to contain oil spills, Duke explains. Floating hard boom, most often seen in media reports, is used to corral or deflect floating oil slicks. Absorbant boom soaks up oil. Fire-proof boom is used in operations burning off oil slicks. "About 80 percent of our business is floating boom," says Duke.
On the west side of the Mississippi River in Terrebonne Parish, parish public safety officer Ralph Mitchell is attending a meeting Wednesday with representatives from the US Coast Guard and British Petroleum (BP) to hear their plan to protect Terrebonne’s coastline.
“We have questions about what sort of resources, like boom, will be available,” says Mr. Mitchell. “We understand that you can’t string boom across the whole parish, and that right now this equipment needs to be in areas where the current danger is, but we’re concerned about what will be here if the oil comes our way.”
Booms just one piece of the solution
But according to experts, in most cases oil-containment booms are effective only when skimmer boats and equipment are available to remove oil from the water.
“From most of what I’ve seen on the news, the booms they’re putting out along the Gulf seem to be public relations for the oil company,” says Jerome Milgram, a professor of ocean engineering at the Massachusetts Institute of Technology in Cambridge, who has patented his own boom designs.
