One incident details how a drunken marine apparently filled a hanger with 1,500 liters of JET-X 2.75 percent. It is classified as “hazardous” by the U.S. government, and contains chemicals that cause cancer, neurological and reproductive disorders.
What is of particular concern is that the chemicals were allowed to flow into nearby waterways and the ocean, while U.S. military officials chose not to report the incident to Japanese authorities, or even the affected residents.
17,000 liters of fire extinguishing agent was also released over three days in 2001. This was apparently caused by mechanical and electronic malfunctions. Malfunctioning equipment was also blamed for 3,400 liters of liquid released between 2012 and 2014.
