Monday’s Okinawa Times wrote that the Defense Ministry’s Okinawa Bureau released on Saturday the results of its water quality survey at a total of 14 locations outside MCAS Futenma following the leakage of foam extinguisher from MCAS Futenma on April 10. According to the bureau, the combined PFOS and PFOA contamination at all the 14 locations was much lower than the level of 50 nanograms per liter set by the Ministry of Environment. The highest reading was 19.3 nanograms and the lowest was less than 0.1 nanograms. The paper noted that the survey was conducted on April 23, 13 days after the leakage.
In a related story, Saturday’s Ryukyu Shimpo wrote that at a news conference on Friday, Okinawa Governor Tamaki expressed the view that the onsite surveys that have been conducted by Okinawa officials at Futenma were insufficient. The paper quoted the governor as saying that he wants to ask the U.S. side to allow Okinawa officials to conduct additional surveys, including sampling of soil and water at the base, for the purpose of ensuring the health, safety, and lives of the Okinawan people.
