Near Yokota Air Base, Japan a group of western Tokyo residents urge the Japanese government to test water at the home of U.S Forces Japan due to concerns of toxic firefighting foam. The residents’ group tested the blood of people living downstream of Yokota and found that more than half had high levels of PFAS in their blood.
In 2012 about 800 gallons of concentrated firefighting foam seeped into the ground from a storage tank at Yokota. The ministry states that “We will take appropriate measures by consulting with related local governments in regards to entering the base and conducting a survey.”
