A diver in what started out as a white dive suit pauses after inspecting the tanks on the Davy Crockett. The Crockett is a former ship converted to a barge that is beached on the Columbia River. |
Tar balls from the Davy Crockett have turned up in the Columbia River , four miles downstream from the beached and broken barge.
The small, dark, sticky globs were discovered below the Interstate 205 Bridge on Tuesday and Wednesday.
“We’ve got people downstream monitoring for sheening,” said Ecology spokeswoman Kim Schmanke. “I believe these were found by Ecology, actually.”
Tests showed the tar balls do not contain polychlorinated biphenyls or heavy metals. Officials believe the tar balls were loosened and escaped into the river as workers removed heavy bunker fuel from the 431-foot vessel sitting on the north bank of the river between Vancouver
Anyone who discovers what they believe to be tar balls should contact the National Response Center
