Tar ball troubles to be expected, watchdogs admit, Tri-Parish Times, January 20, 2011:
Tar balls seen coming ashore on Elmer’s Island and sheen from what appears to be new oil deposits at Grand Isle are a matter of concern, but not surprising, according to regional government officials or environmentalists working to restore coastal areas. ...
"I haven’t seen that quantity of tar balls washing up since shortly after the well was capped,” [said Peter Brabeck, an environmental monitor for the Louisiana Bucket Brigade]...
Scientists had warned that underwater plumes still exist following cleanup efforts and would surface for years following the spill. Brabeck said what he has witnessed suggests that plumes might be behind this situation.
“I found tar balls that were not as weathered as they have been in the past. The quantity of tar balls is increasing as well as the size,” Brabeck said. He added that the pier at Grand Isle State Park offers a view of black water. “This is not the same oil coming up from tide washes,” he said. “I spend a lot of time in Grand Isle and I haven’t seen the oil look like this since the well was capped. There is a visible sheen on the water.”
