The extent of the environmental impact to American Samoa from the deadly tsunami is still unclear.
Pollutants from cars, boats and the island's main power station washed over parts of the coast a week ago.
Clint Owens is in the US territory.
"The American military is still cleaning up hazardous chemicals that were swept up by tsunami and deposited by land and in the ocean. Amir Addmishani of the American military's Pacific Command Joint Taskforce for Homeland Defence says there is no question there is a lot of toxic material to clean up. But he says at this stage they can't really be sure how bad the environmental situation is. Locals are also raising questions about what effects there will be in the harbour area of the capital, Pago Pago."
