Ryukyu Shimpo wrote that Defense Minister Kono said at a session of the Upper House Committee on Foreign Affairs and Defense on Tuesday that his ministry will utilize the tentative benchmark set last month by an experts’ panel of the Ministry of the Environment regarding the contamination of PFOS and PFOA. The Environment Ministry set a benchmark of the total value of 50 nanograms per liter of PFOS and PFOA. Kono was quoted as saying that his ministry will use the benchmark in discussions on the U.S.-Japan environmental agreement to supplement SOFA. The paper wrote that officials of the governments of Japan, Okinawa, and Ginowan entered MCAS Futenma based on the bilateral agreement to take samples of water and soil there in response to the incident in April in which foam extinguisher containing PFOS leaked at the base. Kono commented on the onsite survey by  Japanese authorities by saying that they were able to take all samples necessary for analysis.
