Elevated levels of two banned pollutants used by the US military have been detected in groundwater running under Marine Corps Air Station Futenma on Okinawa, Japanese officials have said. The Pentagon won’t let Okinawan officials on base to investigate.
The carcinogenics perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) were found in high concentrations in underground water during surveys in August and January, the Okinawa prefectural government’s environmental protection department said in a statement.
Japan banned the manufacture and importation of both chemicals in 2010. They are synthetic, fully fluorinated organic acids that have been linked to tumors, increases in body and organ weight and death in animals, Okinawan officials said. PFOS and PFOA are used in firefighting foam, aircraft grease, water-repellant materials and fluorine chemicals.
