Kyle Hopkins of McClatchy follows up on the question of how we learned from the Exxon Valdez disaster about long-term health effects experienced by cleanup workers. In short, we have no peer-reviewed studies on this important topic, even though occupational health experts called for long-term monitoring of workers. Hopkins writes:

Exxon has consistently maintained that there’s no evidence spill workers experienced any adverse health effects as a result of the cleanup. Spokeswoman Cynthia Bergman said she isn’t aware of any long-term study the company conducted on its own.

“The challenge is largely due to the fact that cleanup workers tended to be transient, temporary workers, which made any medical follow-up difficult,” she said.

Sandee Elvsaas, who was director of the spill response operations for oil services firm Veco Corp. in the village of Seldovia, disputes that. She said she still has names of workers she sent out to spray beaches and boats fouled by the spill and who got sick.

“The people from the village are still here. . . . We’re here. They just haven’t come to ask,” Elvsaas said.

“Terrible rashes and headaches and vomiting. They were nauseated . . . These were not the same people I sent out,” she said.

NIOSH also hasn’t conducted long-term research on the health of Exxon Valdez cleanup workers – but they’ve evidently learned from the World Trade Center experience that it’s important to set up a registry of workers. After repeated requests, BP has now provided NIOSH with a worker roster.

Another reason that we lack good information about the effects of that oil spill and its cleanup is that the people with the worst symptoms were more likely to win legal settlements against Exxon – but the settlements required that the records be sealed.

Even if we don’t know much about long-term health impacts of the Exxon Valdez disaster, I hope we’ve at least learned how important it is to get the necessary information and study it.
