Charleston, W.Va. (AP) -- The West Virginia National Guard is still trying to locate about 25 troops who were potentially exposed to a toxic chemical at an Iraqi water treatment plant in 2003.
Spokesman Lt. Col. Mike Cadle said Monday that the guard learned in November that as many as 150 members were in the Basra area and potentially exposed to hexavalent chromium.
He says that number has since been narrowed to about 125.
The guard wants the soldiers to get health screenings.
About one-third of the members are still with the guard and contacting them was simple.
But those no longer with the guard aren't required to maintain contact.
Cadle says efforts to reach them have proven difficult.
