The Okinawa Defense Bureau of the Ministry of Defense tested the final 61 of 83 barrels that were unearthed from land adjacent to the Kadena Air Base fence line. While it found they contained ingredients used in Agent Orange, they were of the incorrect consistency and quantities, leading officials to believe they were to be used as a common herbicide.
The defense bureau also reiterated that it was unlikely that the barrels were a health risk. Tests have shown the air and water, on and off base, are safe.
“There is no evidence that the barrels contained Agent Orange,” the report said. It was posted on the defense bureau’s website earlier this month. “The soil samples that found dioxins and herbicides were taken from immediately beneath the barrels. It is highly unlikely that the ground in the vicinity area is polluted with dioxins of higher levels.
