Okinawa Times front-paged a report saying that the Ministry of Environment released on Tuesday the results of its nationwide water quality survey in fiscal 2020 for which it checked rivers and springs near facilities that could be sources of PFOS, PFAS, and PFHxS contamination. At 4 of the 14 locations surveyed in Okinawa, PFOS and PFOA above the levels set by the government were detected. At a spring near Kadena AB, 1,100 nanograms per liter of these chemicals, or 22 times the provisional government standard of 50 nanograms, were detected. Some 450 nanograms of the chemicals were also detected in a river that runs near the base. Ryukyu Shimpo ran a similar inside-page report, adding that the ministry surveyed a total of 143 locations nationwide and that chemicals exceeding the permissible levels were detected at 21 locations in 12 prefectures.
