(Ramon Tomey) More than 2,400 liters of “firefighting water” containing per- and polyfluoroalkyl substances (PFAS) were released from a U.S. military facility in the southern Japanese island of Okinawa. Heavy rain brought the chemicals into bodies of water at Uruma city and other nearby locations. The June 10 incident also added to the chemicals that have accumulated in the city’s Tengan River, which already had high PFAS concentrations.
