The U.S. military has rejected requests from Okinawa for on-site inspections at its bases following detections of PFAS around the facilities. Japan's Defense Ministry announced the decision on Friday. The refusal stems from a lack of clear evidence linking the bases to the contamination and flaws in the prefecture's sampling plans.
Japan's Defense Ministry announced on Friday that the U.S. military has turned down Okinawa Prefecture's requests for inspections at American bases in the area. Per- and polyfluoroalkyl substances, known as PFAS, have been detected in nearby rivers and other sites, sparking worries about possible impacts on drinking water supplies.
The facilities in question include the U.S. Marine Corps' Futenma Air Station in Ginowan City, Camp Hansen in areas such as the town of Kin, and the U.S. Air Force's Kadena Air Base in regions including the town of Kadena. Since 2016, Okinawa has submitted four separate requests for access to these sites.
In a consolidated response, U.S. authorities stated that inspections would only be considered if there were mutually agreed environmental standards to evaluate sampling results properly and if there was clear scientific evidence pinpointing the U.S. facilities as the pollution source. The prefecture's proposals fell short, particularly in precisely identifying locations for water and soil sampling.
At the same time, U.S. Forces Japan recognized that the chief concern with PFAS is its effect on drinking water and indicated that access might be granted if the goal was to verify water safety, provided conditions were met. The Defense Ministry has informed the prefectural government of the U.S. position but did not reveal the date of the response.
This rejection highlights ongoing challenges in U.S.-Japan environmental collaboration, intensifying local concerns over public health.
