An Okinawan group of activists and physicians known as the Liaison to Protect the Lives of Citizens Against PFAS Contamination has taken the extraordinary step of collecting and analyzing blood samples from 387 residents of the tiny island who live near several U.S. military installations. The results confirm the worst fears of Okinawans regarding the military’s reckless use of PFAS over the last 50 years. Average blood levels for three PFAS compounds: PFOS, PFOA, and PFHxS, were about 25 nanograms per milliliter, (ng/mL), or parts per billion, for those tested from the cities of Ginowan, Kin Town, and Chatan. Marine Corps Air Station Futenma is located in Ginowan.
