Okinawa Times wrote that concerning the detection of high concentrations of perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) in rivers and springs near Kadena AB and MCAS Futenma, an official of the town of Chatan told a municipality assembly session on Wednesday that the levels of these contaminants in a river and a spring near Kadena were lower than the standard set by the United States. In the spring water, 23.7 nanograms of PFOS and PFOA per liter was detected, and 14 nanograms were detected in the river. These figures are lower than the 70 nanograms that the U.S. Environmental Protection Agency establishes as the maximum safe level of lifetime exposure to PFOA and PFOS from drinking water. The town posts the results of its water quality test on its official website.
