St. Tammany President Wants Halt of Dispersant Use

New Orleans, La. – Davis says dispersants being used to break up the oil spill are forming tar balls that sinlk below the surface and are drifting in water currents into the lake. He says it's impossible to fight oil that can't be seen as it drifts under booms and past other barriers.
But retired Coast Guard Admiral Thad Allen says Lake Pontchartrain's contamination may not be the dispersants fault.

"I'm not sure there's a causal link between the incident and the location of tar balls and the use of dispersants. I'm not ruling it out summarily but I would have to take a look at it."

Allen says he will review the matter with the National Oceanic and Atmospheric Administration before making a decision.
