Six months ago, dangerous levels of dioxin were discovered near two U.S. Department of Defense schools on Okinawa Island — but only now are many service members based there learning the full extent of the contamination.

Parents whose children attend the potentially poisoned facilities at Kadena Air Base claim the Pentagon has failed to inform them of the risks or investigate whether the pollution extends onto the school ground. Many are accusing the military authorities of endangering their children's health and now they have formed a group to demand answers.

The focus of parents' fears are the playing fields of Bob Hope Primary School and Amelia Earhart Intermediate School, facilities operated by the Department of Defense for the children of U.S. service members.
