Documents released in September 2015 by the Pentagon under the Freedom of Information Act reveal that Agent Orange dioxin was discovered at the U.S. Army's Machinato Service Area (MSA), Urasoe City, Okinawa, in the 1970s. The 82 pages of reports produced by the U.S. Army, Navy and Marine Corps focus on a 46,000 square-metre outdoor storage area within the base which was used to store “retrograde shipments from Viet-Nam” (1) -including herbicides - during the 1960s and 1970s. Following tests of the soil and water in the mid-1970s, USMC documents cite the discovery of a “high concentration” of dioxin in the area (77); a United States Forces Japan report specifies the detection of “dioxin (agent orange component)” in 1975 (2). The findings contradict Pentagon assertions as recently as 2015 that Agent Orange was never stored on Okinawa.
