Gulf Spill Solution, Or New Hazard?

By David Funkhouser — June 8, 2010

A Connecticut company that makes a line of what it labels “green” products for auto and marine use says it has just the thing for cleaning up the Gulf oil spill: A nanotech-based, biodegradable oil dispersant.

But a number of scientists and environmental groups are warning that the firm’s marine oil dispersant relies on nanoparticles in an untested formulation that could cause more harm than good.

Green Earth Technologies’ oil dispersant uses a detergent based on plant-based oils and other unspecified compounds.

Stamford-based Green Earth Technologies defends its products as harmless, and says a protest letter sent to the U.S. Environmental Protection Agency by environmental groups has unfairly characterized the company’s dispersant. The EPA, which has been flooded by suggestions for using various products, has basically told the company to get in line along with other companies proposing Gulf solutions.

“This company may be right on, we don’t know that,” said Penny Vlahos, assistant professor of marine science and chemistry at the University of Connecticut at Avery Point in Groton. “It’s good someone is asking questions, and it’s good they have to defend themselves.”

Millions of gallons of oil have gushed into the sea in the seven weeks since the Deepwater Horizon oil rig exploded in the Gulf of Mexico, uncorking a well a mile below the surface. Efforts to fight the spill have included spreading more than a million gallons of oil dispersant.

Vlahos and two UConn colleagues are just back from a one-day conference in Baton Rouge at which 200 scientists in ocean and coastal research consulted with federal officials engaged in the oil cleanup. Vlahos described the Gulf crisis as “a bit of a feeding frenzy” for companies trying to promote their products and techniques for environmental cleanup.
